Hi @ReWi,
thanks for the report. I confirmed that the Excel Writer writes the following as creator (matching “Verfasser”?) to the XLSX file <dc:creator>Apache POI</dc:creator> (although not PIA, also not very helpful metadata).
However, I was unable to find any absolute path to the workbook inside the XLSX file itself, so I am not sure what to look for – it also is not a CoreProperty according to POI (the Java library we use). Would it be possible to create a small sample file and send me the versions before and after cleaning?
For now, I opened an internal ticket (AP-23036) on your behalf to not even write the info if they make problems processing the file.
Best,
Manuel
