I've tried mat2 and found Metadata Cleaner, but underneath it relies in mat2 and it doesn't work (mat2 removes the data in the sheets, Metadata Cleaner removes the file entirely).

I was trying to get an universal solution to remove metadata from any kind of files (remove the file creator name, etc), but it seems that even removing metadata kist from Excel files is already tricky.

I feel I'm missing something, because to anonymize personal data from public available information should be a common task.
