I attached a test file. If I open this file in Excel 2010 or 2013 - it opens correctly. But when I open it in Excel 2007 - see window with error “Excel found unreadable content in filename.xls. Do you want to recover the contents of this workbook?”. File was generated by Aspoce.Cells. Probably a mistake in cell with hyperlink. It contains symbol “[”. Files without such symbols in links open correctly.
We observed the issue in MS Excel 2007 only as you pointed out. Could you download and try our latest version/fix: Aspose.Cells for .NET v7.7.1.4 if it makes any difference.
If you still find the issue, kindly create a sample console application with v7.7.1.4 on how did you create such a file to reproduce the issue on our end and provide us here, we will check it soon.
I created test app and attached it to this message. I think this error occurs then special symbols in link aren’t escaped to HTML codes. Is it bug or I should convert links addresses manualy?
After an initial test, I observed the issue as you mentioned by using your sample code/project. I can find “Excel found unreadable content” error when opening the output file into MS Excel 2007, it works fine in MS Excel 2010 though.
I am afraid, the ticket logged earlier as CELLSNET-42341 isn’t resolved yet. Currently it is pending for analysis, and is in the queue with other tasks. Unfortunately, we can not share the estimated timeline for the fix unless we have properly analyzed the problem cause on our end.

Thank you for bringing this issue to our knowledge.
We are able to observe the problem while using the latest version of Aspose.Cells for .NET 8.0.0.2 with the following piece of code. We have noticed that the resultant spreadsheet causes Excel 2007 to throw message regarding the unreadable contents in the spreadsheet whereas same file does not exhibit any problem when loaded with Excel 2010. We have logged a new ticket in this reference under Id CELLSNET-42554. Please spare us little time to properly analyze the problem cause, and to provide a fix.
