GoKawiilNew browser tool extracts all comments from Google Sheets exports
A developer launched a Show HN project that lets users upload an exported .xlsx Google Sheets workbook and extracts every comment thread from it in one list, showing the tab, cell reference, reply chains, and resolution status for each. The tool currently works only with spreadsheet files, not Google Docs or Slides. A companion add-on also lets users pull comments directly inside Google Sheets into a new tab without needing to export or upload a file.
