Excel has problems opening xlsx file with protected sheets after simple open/save by Aspose Cells


Hi, we really have big problems processing existing Excel xlsx files - seems to be an Aspose bug related to protected sheets.

Zip file has been attached AsposeErrorReporting.zip (2.2 MB)

  • which contains the following:

ErrorReport.docx - contains description of problem with screen dumps and how to reproduce.
AsposeExcelTest.aspx - contains simple open/save code to reproduce problem. Please adjust input/output paths before running.

PP_WB.xlsx - input file.
PP_WB-OUT.xlsx - output file from running code sample.

Thanks and kind regards
Sven Andersen



Thanks for the template file, screenshot and sample code.

Please try our latest version/fix: Aspose.Cells for .NET v17.10.4:

I have tested your scenario/case a bit with v17.10.4, it works fine and the output file is ok.
