Good to know

Pro mode uploads the document, edits its internal metadata, and deletes it immediately. Up to 4.5MB per file.

Excel (XLSX) and PDF are not supported for internal document-date editing. For those formats, standard File Date (OS) mode changes the file's created/modified date only.

FAQ

Can't I change an Excel file's creation date?

XLSX is not currently supported for internal document-date editing. Standard mode can still change the created/modified date shown in your file manager.

Does the 'modified date' in properties change too?

The metadata date fields are updated to your chosen time. To match the file's own created/modified dates as well, you can also run standard mode.
