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.

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.

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
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);

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'm investigating for a client feature and I didn't reach the right answer.
This is quite simple : the user edits a full table with datas ( numbers ), chooses which cells receive the sum of which cells and export it.
In Angular we can keep the calculation and hide it to show the result. But what I would like to do is to keep the calculation active when exporting on xls.
For ex.
Cell1 = 25 Cell2 = 45
Cell3 = 70 (Sum(Cell1,Cell2));
In the XLS file It should keep the Sum() function instead of a "flat" 70.
Am I clear enough ? Does someone know a library that can do this ? or the best process to succeed in this feature ?
Excel files are essentially XML Documents.
However building Excel using plain XML is a crazy job...
You can try using the library (ClosedXML) if you are using .NET. https://closedxml.codeplex.com/
It makes much easir to build Excel files.
var wb = new XLWorkbook();
var ws = wb.AddWorksheet("Sheet1");
ws.Cell("A1").SetValue(1).CellBelow().SetValue(1);
ws.Cell("B1").SetValue(1).CellBelow().SetValue(1);
ws.Cell("C1").FormulaA1 = "\"The total value is: \" & SUM(A1:B2)";
var r = ws.Cell("C1").Value;
Assert.AreEqual("The total value is: 4", r.ToString());
// It also works if you use: ws.Cell("C1").GetString()
