FAQ
Can this extract comments from every Excel worksheet?
Yes. Select All sheets to scan the workbook rather than one worksheet.
What information is included in the comment report?
The CSV contains worksheet name, cell address, comment author, and comment text.
Are modern threaded Excel comments supported?
Support is limited to comments exposed by the SheetJS CE parser; some threaded comments may be unavailable.
Does extraction remove comments from the workbook?
No. This tool creates a report and does not modify the source file.
Can CSV files contain extractable Excel comments?
No. CSV has no workbook comment structure, so use an Excel workbook for this task.
