According to: https://github.com/agershun/alasql/wiki/XLSX you can send in the sheetid to read out a different sheet.
I can't however find any way to read out the available sheets.
Does anyone know how this should be done?
Instead of using alasql, first read your workbook yourself using the xlsx plugin
// file is instanceof File object
let workbook = XLSX.read(URL.createObjectURL(file));
console.log(workbook.SheetNames);

In my application, there are two buttons(export & import ). Using the export button I can download an excel file, in that downloaded excel file, there are lots of blanks fields.
I need to upload the same file using import button but if I upload the same file then I can get many mandatory fields validation message because of blank fields. Instead of uploading the same file I have another excel file, in which every blank field are filled.
In the exported file, there is a unique id which is generated in the run time and I have to set the same unique id into another excel file, in which every blank field are filled same as the exported file but unique id is different. otherwise, I will get a validation message.
I want to replace the epricer quote number 8766876 to 4181981 in new import file.
Possibly duplicate of following question :
update excel cell in selenium webdriver
Possible solution from link :
InputStream inp = new FileInputStream("workbook.xls");
Workbook wb = WorkbookFactory.create(inp);
Sheet sheet = wb.getSheetAt(0);
Row row = sheet.getRow(2);
Cell cell = row.getCell(3);
if (cell == null)
cell = row.createCell(3);
cell.setCellType(Cell.CELL_TYPE_STRING);
cell.setCellValue("a test");
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
You cannot update Excel using Selenium, Selenium is a series of libraries that are used to drive a browser, they cannot interact with Excel documents.
If you want to interact with Excel documents you will need to use a library specifically designed to do that, some options are:
Apache POI
DocX4J
JExcelAPI
I have three files:
Activefile - where my code is stored and run
Databasefile - where my raw data is housed (has lots of protection)
Copyofdatabasefile - is a copy without the protection
I have a macro that runs in activefile to update a databasefile excel file, later in the macro, I then use the saveas method on the databasefile to make a copyofdatabasefile file, I remove some functionality to allow people to access the data easily without going through some of the checks on the main databasefile.
When saving the copyofdatabasefile, the links in my active file are updated to look at the new copyofdatabasefile file. I don't want this to happen.
How can I adjust my excel links/code to ensure that the links in my file aren't transferred across to the copyofdatabasefile?
Saveas macro options are currently:
Databasefile.SaveAs filename:="\\somelocation\copyofdatabasefile.xlsx", FileFormat:=51, CreateBackup:=False
Using the Workbook.SaveCopyAs Method should work.
If your original file is xlsx use
Databasefile.SaveCopyAs Filename:="\\somelocation\copyofdatabasefile.xlsx"
Note that it saves in the same FileFormat as the original file only!
If your original file is xlsm use
If you need to change the file format (eg from xlsm to xlsx) you need to save as copy in the original file format first, then reopen that copy with Workbooks.Open() and then use .SaveAs to change the FileFormat.
Databasefile.SaveCopyAs Filename:="\\somelocation\copyofdatabasefile.xlsm" 'if original file was xlsm
Dim wb As Workbook
Set wb = Workbooks.Open("\\somelocation\copyofdatabasefile.xlsm")
wb.SaveAs filename:="\\somelocation\copyofdatabasefile.xlsx", FileFormat:=51, CreateBackup:=False
wb.Close False
Kill "\\somelocation\copyofdatabasefile.xlsm" 'delete old format
Im trying to find a way to convert xls files to pdf, and gembox spreadsheet is great for this. But i need to be able to make it fit to one page as you can when printing to pdf via excel.
Try specifying FitWorksheetWidthToPages and FitWorksheetHeightToPages properties.
For example like the following:
ExcelFile workbook = ExcelFile.Load("Sample.xls");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;
worksheet.PrintOptions.FitWorksheetWidthToPages = 1;
worksheet.PrintOptions.FitWorksheetHeightToPages = 1;
workbook.Save("Sample.pdf");
I hope this helps.
I am writing an application that works with Excel files. So far I have been using Gembox spreadsheet to work with excel files. However, I discovered using Gembox spreadsheet I can save pics to excel files, but not retrieve them. Anyone can recommend how to retrieve a pic from excel file? Thank you
Here is how you can retrieve an image from an Excel file with GemBox.Spreadsheet:
ExcelFile workbook = ExcelFile.Load("Sample.xlsx");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;
// Select Picture element.
ExcelPicture picture = worksheet.Pictures[0];
// Import to PictureBox control.
this.pictureBox1.Image = Image.FromStream(picture.PictureStream);
// Or write to file.
File.WriteAllBytes("Sample.png", picture.PictureStream.ToArray());
I have WPF DataGrid (VS2010 C#). I copied the data from DataGrid to Clipboard and write it to an Excel file. Below is my code.
dataGrid1.SelectAllCells();
dataGrid1.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader;
ApplicationCommands.Copy.Execute(null, dataGrid1);
dataGrid1.UnselectAllCells();
string path1 = "C:\\test.xls";
string result1 = (string)Clipboard.GetData(DataFormats.CommaSeparatedValue);
Clipboard.Clear();
System.IO.StreamWriter file1 = new System.IO.StreamWriter(path1);
file1.WriteLine(result1);
file1.Close();
Everything works out OK except when I open the excel file it gives me two warning:
"The file you are trying to open
'test.xls' is in a different format
than specified by the file extension.
Verify that the file is not corrupted
and is from a trusted source before
opening the file. Do you want to open
the file now?"
"Excel has detected that 'test.xls' is
a SYLK file, but cannot load it."
But after I click through it, it still open the excel file OK and data are formated as it supposed to be. But I can't find how to get rid of the two warnings before the excel file is open.
You need to use csv as extension. Xls is the Excel file extension.
So
string path1 = "C:\\test.csv";
should work.
A problem like yours has already been described here : generating/opening CSV from console - file is in wrong format error.
Does it helps to solve yours ?
