Spreadsheet and Excel tools
Your spreadsheet has secrets. Some of them are hiding: sheets marked very-hidden, formulas that reference internal ranges, author names and company fields in document properties. These tools parse the workbook package locally, show you what is really inside, and write fresh sanitized outputs — all without your data leaving the browser.
One sheet per CSV, automatic delimiter detection, and a fresh clean workbook as output.
