Apps Script (Google Sheets) How to perform .setHiddenValues with an Array - arrays

I have some values stored in an Array and now I want to remove ALL the values stored in this array from a filter.
The values are stored correctly in the array but I don't manage to remove the values from the filter.
The Array's name is HideValues
Here is some code:
var p = 0;
spreadsheet.getSheetByName('TEM Tool Data').getRange('\'TEM Tool Data\'!E1').activate();
var criteria = SpreadsheetApp.newFilterCriteria();
//Remove all PID´s from the filter
while (p < HideValues.length){
criteria.setHiddenValues([HideValues[p]]).build();
p++;}
//Filter
spreadsheet.getSheetByName('TEM Tool Data').getFilter().setColumnFilterCriteria(5, criteria);
//Copy filtered area
spreadsheet.getRange('A2:I1386').activate();
//Paste
spreadsheet.getSheetByName('Visualization').getRange('A5').activate();
spreadsheet.getRange('\'TEM Tool Data\'!A2:I1386').copyTo(SpreadsheetApp.getActiveRange(),
SpreadsheetApp.CopyPasteType.PASTE_NORMAL, false);
spreadsheet.getSheetByName('Visualization').getRange('J3').activate();
};

You don't need to loop through the array
If your array is something like var HideValues = [1,2,3,4,5];,
you can simply specify criteria.setHiddenValues(HideValues).build(); - without the while loop
Also:
To a filter, you should create it first (if not already done) and apply it to a range, not sheet:
var filter = spreadsheet.getSheetByName('TEM Tool Data').getDataRange().createFilter();
filter.setColumnFilterCriteria(3, criteria);
You should apply it to a range, not a sheet

Google Apps Script: how to create an array of values for a given value by reading from a two column list?

I have a set of data in a Google spreadsheet in two columns. One column is a list of article titles and the other is the ID of a hotel that is in that article. Call it list1.
Example data
I would like returned a new list with article titles in one column, and an array of the hotel IDs in that article in the other column. Call it list2.
Example data
There are thousands of lines that this needs to be done for, and so my hope was to use Google Apps Script to help perform this task. My original thinking was to
Create column 1 of list2 which has the unique article titles (no script here, just the G-sheets =unique() formula.
Iterate through the titles in list2, looking for a match in first column of the list1
If there is a match:
retrieve its corresponding value in column 2
push it to an empty array in column two of list2
move onto next row in list1
if no longer a match, loop back to step 2.
I've written the following code. I am currently getting a type error (TypeError: Cannot read property '0' of undefined (line 13, file "Code")), however, I wanted to ask whether this is even a valid approach to the problem?
function getHotelIds() {
var outputSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('list2');
var lastRow = outputSheet.getLastRow();
var data = outputSheet.getRange(2,1,lastRow,2).getValues();
var workingSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('list1');
var lastActiveRow = workingSheet.getLastRow();
var itemIDS = [];
for (var i=1; i<=data.length; i++) {
var currentArticle = data[i][0];
var lookupArticle = workingSheet[i][0];
if (currentArticle === lookupArticle) {
var tempValue = [workingSheet[i][1]];
itemIDS.push(tempValue);
}
}
}
Use a simple google sheets formula:
You can use a very simple formula to achieve your goal instead of using long and complicated scripts.
Use =unique(list1!A2:A) in cell A2 of list2 sheet to get the unique hotels.
and then use this formula to all the unique hotels by dragging it down in column B.
=JOIN(",",filter(list1!B:B,list1!A:A=A2))
You got the idea right, but the logic needed some tweaking. The "undefined" error is caused by the workingSheet[i][0]. WorkingSheet is a Sheet object, not an array of data. Also, is not necessary to get the data from list2 (output), it is rather the opposite. You have to get the data from the list1 (source) sheet instead, and iterate over it.
I added a new variable, oldHotel, which will be used to compare each line with the current hotel. If it's different, it means we have reached a different Hotel and the data should be written in list2.
function getHotelIds() {
var outputSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('list2');
var outLastRow = outputSheet.getLastRow();
var workingSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('list1');
var lastActiveRow = workingSheet.getLastRow();
var sourceValues = workingSheet.getRange("A2:B" + lastActiveRow).getValues();
var itemIDS = [];
var oldHotel = sourceValues[0][0]; //first hotel of the list
for (var i = 0; i < sourceValues.length; i++) {
if (sourceValues[i][0] == oldHotel) {
itemIDS.push(sourceValues[i][1]);
/*When we reach the end of the list, the oldHotel variable will never be different. So the next if condition is needed. Otherwise it wouldn't write down the last Hotel.
*/
if (i == sourceValues.length - 1) {
outputSheet.getRange(outLastRow + 1, 1, 1, 2).setValues([
[sourceValues[i][0], itemIDS.toString()]
]);
}
} else {
outputSheet.getRange(outLastRow + 1, 1, 1, 2).setValues([
[sourceValues[i - 1][0], itemIDS.toString()]
]);
oldHotel = sourceValues[i][0]; //new Hotel will be compared
outLastRow = outputSheet.getLastRow(); //lastrow has updated
itemIDS = []; //clears the array to include the next codes
}
}
}
I also converted the itemIDS array to a String each time, so it's written down in a single cell without issues.
Make sure each column of the Sheet is set to "Plain text" from Format > Number > Plain Text

How to build multi-dimensional arrays in the appropriate orientation. (Rows/Cols in correct places)

I'm working on building a Google Sheets-based tool to calculate the cost of making various machined and fabricated parts. As it currently sits, there are about 60 different variables that I modify each time I build an estimate. Things like "number of parts," "length of bar to cut each part from," "cost/bar," "machining time," "machining rate," etc. All of these values I have populated on one sheet, and laid out in a way like. I want to make a button that takes a "snapshot" of all of these values, and stores them on another sheet for later reference. I'd then, ideally create another button, that allows me to re-populate all of the cells based off of a unique ID (such as Part #). This would let me tweak an estimate, or even refer back to material sizes etc in a meaningful way.
So far, I've created a "Named Range" for each of the values, so that as I change the layout, or add values, my script code should update accordingly, instead of using direct cell references.
I've built a few functions to get and set the value's of these named ranges. They're working as expected(i think) for what I'm trying to do. But when I try to place the array of Named Ranges inside of a multi-dimensional array of the named ranges WITH their respective values, I'm running into an issue where each named range is a ROW and their respective value is a second Column. And I need it swapped
I'm not super comfortable with multi-dimensional arrays and am thinking myself in circles trying to figure out how to transpose this logically. My gut says the way I'm attempting to build the arrays is my problem, not just how I'm iterating through them.
function saveCurrentValues(){
//set master spreadhseet
var ss = SpreadsheetApp.getActiveSpreadsheet();
//set calc and save sheets to vars
var calcSheet = ss.getSheetByName('Part Cost Calculator')
var saveSheet = ss.getSheetByName('Saved Parts');
//set named ranges from calcSheet to array
var namedRanges = calcSheet.getNamedRanges();
var savedValues = new Array();
//find next available row for save data (currently troubleshooting)
var nextAvailSaveRange = saveSheet.getRange(1, 1, 60, 2);
//iterate through array and call getNamedRange() function to return name and current value
for(i = 0; i < namedRanges.length; i++){
savedValues[i] = getNamedRange(namedRanges[i].getName());
}
nextAvailSaveRange.setValues(savedValues);
}
function getNamedRange(name){
var ss = SpreadsheetApp.getActiveSheet();
var value = ss.getRange(name).getValue();
Logger.log([name,value]);
return [name, value];
}
As you can see by how I had to temporarily format the nextAvailSaveRange, it needs 60 ROWS, and only two columns, because of how the array is constructed. I'd like to better understand how I'm creating this multi-dimensional array vertically instead of horizontally, and how to fix it!
Once this is done, I'd like to create headers that match the Named Ranges on my save sheet, to allow me to iterate through functions and look for a match to the appropriate column by name. That way if I add more values or change their order, or the order of the array, it wont matter. I think I'll be able to figure that out pretty easily if I can control these damn arrays better!
I agree with the OP. Array building AND iteration are the immediate problems and they are the stumbling block to the development of the spreadsheet.
The OP has a raised number of issues, however the most immediate, and the one to be resolved under this answer, is the copying of a list of parts from one sheet to another. In the OP's code, named ranges were retrieved and used as a basis for creating the copy of the list of parts. However, this also creates a duplicate set of named ranges on the target sheet. In my view this was unnecessarily complicating the duplication of the parts list since it is easy to programmatically create/update a list of named ranges.
The following code consists of three functions:
so_5466573501() - Copies the list of parts from one sheet to another.
Named Ranges are ignored; the OP's stumbling block is the iteration of the raw data and management of arrays. This code deals only with that aspect as a means of simplifying this issue.
createnamedranges() - Programmatically creates/updates Named ranges.
This code is included to assure the OP that it is not important to make named ranges the focus of the duplication by showing how easy it is to programmatically turn a list of parts into a series of Named Ranges (for development, I created 60 Parts and the entire code executes in under a 1 second). The code assumes a list in two columns (Column A = Parameter Name, Column B = Parameter value). The code loops through the list creating/updating a set of named ranges - the range name is the Parameter Name in Column A, and the range itself is the the corresponding row in Column B. The name of the sheet is set in a variable, so this function can be easily adapted.
deletenamedranges() - Programmatically deletes Named ranges.
This code deletes all the Named Ranges from a given sheet. This function is included because the OP's existing code creates duplicate named ranges, and it might be necessary to quickly delete them from a sheet. The sheet name is stored as a variable, so the function can be easily adapted.

ADDENDUM: - Copy based on Named Ranges
The original so_5466573501 assumes that the parts are in a simple 2 column-list; in which case, Named Ranges are irrelevant.
The following code assumes that the parts are not in a list but scattered, in no particular order, throughout the sheet "Part Cost Calculator". This code is based on obtaining the NamedRanges, identifying the respective Named Range row and column, correlating said row and column to the ENTIRE data range, and then copying the results to the "Saved Parts" sheet. No Named Ranges are created by default on the "Saved Parts" sheet but this can be easily done by using the createnamedranges function (appropriately edited for the correct sheet name).

//Logger.log("DEBUG: Number of named ranges on Parts Cost Calculator = "+numNR);
// get all the data
var dataRangeValues = calcSheet.getDataRange().getValues();
// create an array to temporarily store results
var resultsarray = [];
// Loop through the array of Named Ranges
for (var x = 0; x < numNR; x++) {
var nrName = namedRanges[x].getName();
var nrRange = namedRanges[x].getRange();
var nrRangerow = nrRange.getRow();

Google Sheets Query - build referenced array source dynamically

I have many sheets in my spreadsheet (sheet1,sheet2,sheet3...) and I want to add them all to array, maybe based on any call range? Now I add them manually as below:
=query(
{
INDIRECT("sheet1!$A$3:$V");
INDIRECT("sheet2!$A$3:$V");
INDIRECT("sheet3!$A$3:$V") };
"SELECT Col2, Col3, Col4, ...[etc]")
I want to create any "Settings" sheet and put here all sheets that should be in array, like this:
=query(
{
get_all_sheets_names_from('settings!A1:A100'); // something like this
};
"SELECT Col2, Col3, Col4, ...[etc]")
Is it possible?
My attempts:
https://docs.google.com/spreadsheets/d/1ZMzu6FuVyAJiWfNIHW87OW1Vpg_mM_QdtGs9nq9UXCU/edit#gid=0
I would like the array with data sources to be taken from the G2:G column.
The example in column C shows how this can be done manually. However, I am looking for a solution so that in the query nothing has to be done so that the query can drag an array with the names of the data source from G2:G
1) What i Think
I think it is not possible to use "INDIRECT" in the query parameters, because "INDIRECT" returns a cell reference and the parameters {(); ()} in a query are fixed objects.
An "INDIRECT" on a complete query is not possible either, for the same reason: a query does not return a reference on a cell.
2) Limited soluce
the principle: case1: look in column G the 3rd line (3rd source), if empty then test case 2, otherwise apply the formula with 3 sources.
case 2: if 2nd source is empty then go to case 1, otherwise apply the formula with 2 sources
case 1: if empty then display "no sources" otherwise apply formula with 1 source
Formula
note 1 replace ESTVIDE (fr) by ISBLANK (eng) !!
note 2 : you can test with (G2="source1" and G3="source2),
but it works with G2="source3" and G3="source1"
=SI(ESTVIDE($G$4); SI(ESTVIDE($G$3); SI(ESTVIDE($G$1); "no source(s)";query({((INDIRECT("'"&G2&"'!A1:A5")))};"SELECT Col1")) ;query({(INDIRECT("'"&G2&"'!A1:A5"));(INDIRECT("'"&G3&"'!A1:A5"))};"SELECT Col1")) ;query({(INDIRECT("'"&G2&"'!A1:A5"));(INDIRECT("'"&G3&"'!A1:A5"));(INDIRECT("'"&G4&"'!A1:A5"))};"SELECT Col1"))

Limitations
Off course, this is a formula with only 3 sources max !
It will be verry big and uggly with more sources...
Script
macro is the only solution ?
soluce with Macro
append this script,
it gets value sources values from G2:G30 (you need more...put G100..)
it create the formula and put it on H2
it read max 50 value in each source (see A1:A50 in source code)
it's not so hard to understand,
note : managing macro with GSheet is a another problem, if you needs advices, please post a comment.

if (i>0) { acSources+=";" }

dudes who copy-pasted INDIRECT function into Google Sheets completely failed to understand the potential of it and therefore they made zero effort to improve upon it and cover the obvious logic which is crucial in this age of arrays.
in other words, INDIRECT can't intake more than one array:
=INDIRECT("Sheet1!A:B"; "Sheet2!A:B")
nor convert an arrayed string into active reference, which means that any attempt of concatenation is also futile:
=INDIRECT(MasterSheet!A1:A10)
————————————————————————————————————————————————————————————————————————————————————
=INDIRECT("{Sheet1!A:B; Sheet2!A:B}")
————————————————————————————————————————————————————————————————————————————————————
={INDIRECT("Sheet1!A:B"; "Sheet2!A:B")}
————————————————————————————————————————————————————————————————————————————————————
=INDIRECT("{INDIRECT("Sheet1!A:B"); INDIRECT("Sheet2!A:B")}")
the only possible way is to use INDIRECT for each end every range like:
={INDIRECT("Sheet1!A:B"); INDIRECT("Sheet2!A:B")}
which means that the best you can do is to pre-program your array like this if only part of the sheets/tabs is existant (let's have a scenario where only 2 sheets are created from a total of 4):
=QUERY(
{IFERROR(INDIRECT("Sheet1!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet2!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet3!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet4!A1:B5"), {"",""})},
"where Col1 is not null", 0)
so, even if sheet names are predictable (which not always are) to pre-program 100+ sheets like this would be painful (even if there are various sneaky ways how to write such formula under 30 seconds)
an alternative would be to use a script to convert string and inject it as the formula
A1 would be formula that creates a string that looks like real formula:
=ARRAYFORMULA("=QUERY({"&TEXTJOIN("; "; 1;
FILTER(SNAME(1); SNAME(1)<>SNAME(0))&"!A1:A20")&"}; ""where Col1 is not null""; 0)")
then this script will take the string from A1 cell and it will paste it as valid formula into A2 cell:
function onEdit() {
var sheet = SpreadsheetApp.getActive().getSheetByName('query'); // MASTER SHEET NAME
var src = sheet.getRange("A1"); // COPY STRING FROM
var str = src.getValue();
var cell = sheet.getRange("A2"); // PASTE AS FORMULA INTO
cell.setFormula(str);
}
function SNAME(option) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet()
var thisSheet = sheet.getName();
if(option === 0){ // ACTIVE SHEET NAME =SNAME(0)
return thisSheet;
}else if(option === 1){ // ALL SHEET NAMES =SNAME(1)
var sheetList = [];
ss.getSheets().forEach(function(val){
sheetList.push(val.getName())
});
return sheetList;
}else if(option === 2){ // SPREADSHEET NAME =SNAME(2)
return ss.getName();
}else{
return "#N/A"; // ERROR MESSAGE
};
}
of course, the script can be changed to onOpen trigger or with custom name triggered from the custom menu or via button (however it's not possible to use the custom function as formula directly)
this will cover all your needs to not edit the formula by adding references if new sheets are added. the only drawback is a recalculation of sheet name script... to do so you need to dismantle A1 formula for example by adding ' before the leading = pressing enter and then removing it to fix the formula

Google Apps Script Replace and update cell within a range

I have a Google spreadsheet that I'm trying to remove the word "woo" within a range of cells
So far I've managed to loop through the results and log the results, however I haven't figured how to update that information in the spreadsheet itself.
Any guidance would be welcomed
Thank you
function myFunction () {
var ss = SpreadsheetApp.getActiveSheet().getRange('B:B')
var data = ss.getValues();
for (var i = 0; i < data.length; i++) {
var text = data[i].toString();
var finaltext = text.replace(/woo/g, "");
data[i] = finaltext;
Logger.log(data[i]);
}
}
Use setValues()
Notes:
Usually ss is used as a shorthand for spreadsheet, as it's used on the code for a range it's better to use range as a variable name.
setValues() returns a 2D array, so data[i] returns an array of row values rather than a cell value. To get/set cell values, use data[i][0] notation.
Considering the above replace
var ss = SpreadsheetApp.getActiveSheet().getRange('B:B')
by
var range = SpreadsheetApp.getActiveSheet().getRange('B:B')
then add the following line after the for block.
range.setValues(data);
Regarding text var declaration, replace
var text = data[i].toString();
to
var text = data[i][0].toString();
Using open ended references like B:B could lead to problems. To avoid them be sure to keep the sheet rows at minimum or better instead of using an open ended reference use something like B1:B10.

I am trying to make a json array after getting each records from a grid. I want to add row number of grid as key of each row in json array

I am trying to make a json array after getting each records from a grid in ExtJS 3.4.0. I want to add row number of grid as key of each row in JSON array.
var selected_value = [];
for (var i = 0; i < count; i++)
{
var rec = store.getAt(i);
selected_value[i] = rec.data;
final.push({
"i":selected_value[i],
})
}
What you do there is build an array of objects with each object containing one property called i and that property has the value of the row in it.
I guess you actually just wanted to have an array with the row objects in it, right?
final.push(selected_value[i]);
This will do the job already. No need to specify an object with associative indices.
If you're grabbing all the store's entries already or at least know the range (start and end index) you could just as well skip all the manual item picking and grab a readymade array already:
final = store.getRange();
or
final = store.getRange(from, to);
