Aspose.Cells is adding unwanted styles on save method

I have a empty excel file that only includes the Style “Normal”.

When I open the excel file with Aspose.Cells and save it, it has alot of addtional styles when I open it in Excel again.

Used code:

Aspose.Cells.Workbook wbk = new Aspose.Cells.Workbook(“c://emtpy and no styles.xlsx”);

wbk.Save(“c://temp//emtyp saved aspose.xlsx”,Aspose.Cells.SaveFormat.Xlsx);

so just use this attached excel and open it one time. You will see only the Style “Normal”.

use the code provided on the file and open the saved excel document. there are many styles then.

happens in and also in


Thanks for your posting and using Aspose.Cells.

I have loaded your workbook and tested it by calling the Workbook.CountOfStylesInPool property and it showed 62 styles. So there are 62 styles inside it. It is not necessary these styles are shown in Microsoft Excel but they are internally present inside the xlsx file. Please change the extension to .zip and open it in WinRar and you will find hidden styles inside it.

I have attached the screenshot explaining this issue for a reference.

Thank your for the fast response.

I looked in the initial file and in the file that aspose creates on save and I can see the differences:

Original file:

cellStyle xfId=“24” hidden=“1” builtinId=“30” name=“20% - Accent1”/

Aspose.Cells after save:

cellStyle xfId=“38” name=“20% - Accent1”/

So it looks like aspose ignores the hidden=“1” attribute on saving.

For us this is a critical issue as user should only work with a small list of 10 styles.

In Excel this works without issues. But our solution is also opening and saving this files with aspose and users have to deal with 57 instead of 10 Styles.

Is there a way that I can tell aspose to keep this information?
