Bug report_1_Export data to Excel_format or extension invalid

[Aewolframio]

Good morning. 

I'm using Phyphox version 1.2.0-beta 4, and when I try to download or share data in Excel format, the created file won't open, indicating that the format or extension is invalid. 

I've attached the downloaded Excel file that failed to open and the Python file I'm working on.

Regards

Alberto

Thanks for reporting. We are aware of the problem (see https://phyphox.org/forums/showthread.ph...33#pid4433) and it's already fixed in our internal version. This is just a problem for Microsoft products, unix like systems (this includes macOS) and their tools do not care about file extensions…

Quick fix: change the file extension to .xls (you might need to check the “File name extensions” checkbox in the “View” menu's “Show/hide” section of Windows File Explorer if you have not already done so).

Background: we would like to switch to the “modern” Excel file format, however, the Android library we tried was a performance mess. The roll back of changes unfortunately missed the file extension and the MIME type…
