Formulas are not being saved correctly when a workbook has external links to a workbook that has not been saved

PFA workbook: ExternalLinks.zip (7.1 KB)

In cells A1:A3, there are formulas that link to an external workbook that has not been saved (Book3):

In Aspose, these external links are not properly escaped with single quotes as in the Excel version:

When trying to set the same formula to another cells an error occurs because it is not properly escaped with single quotes (worksheets have spaces in them)

Source code I used with attached workbook:

        using (var workbook =
               new Workbook(
            var worksheet = workbook.Worksheets[0];

            var formula1 = worksheet.Cells["A1"].Formula;
            var formula2 = worksheet.Cells["A2"].Formula;
            var formula3 = worksheet.Cells["A3"].Formula;

            worksheet.Cells["B1"].Formula = formula1;
            worksheet.Cells["B2"].Formula = formula2;
            worksheet.Cells["B3"].Formula = formula3;

The error returned is:
“Unknown token with bracket: 13(Based on cell Sheet1!B2)”



Please notice, after an initial test, I am able to reproduce the issue as you mentioned by using your template file. I got an exception “Unknown token with bracket: …” when resetting the formula back. It looks formulas are not escaped or not retrieved/saved properly. I have logged a ticket with an id “CELLSNET-50759” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.
