My guess here is that Excel uses a 16 bit signed integer for storing the cell content size internally and when the size is greater than that the parser identifies it as being corruption.
My point with the issue is more just about how the Spreadsheet gem might better identify to users that there is an issue with the content being saved, or at worst maybe update the documentation to explain that limitation of Excel?
For my specific issue I've already put measures in place to better sanitise the data being saved, but there may be others who face a similar situation

Failures occur for me in Office 16 (and presumably anything before that).
Sure, will create a PR for the README 👍

Thank you.
- Who created the original File? My guess is you just modified the file.
- Is this on Mac or an PC?

The file was created essentially by the means described above. A spreadsheet was created using the Spreadsheet gem which included a large block of text (> 32K long) in one of the cells. The resulting file would not open in Excel (but would in LibreOffice)

I've tested creating the files using Mac and Linux and opening them with Excel and LibreOffice on Mac and Windows each with the same results.

Ok, thank you. Your explanation sounds totally plausible to me. Can you send me a Pull Request how you would mention that problem to new spreadsheet users in the README file?

both files open in OneDrive/Office 365.
