Remove a forgotten Protect Sheet / Protect Workbook edit password from .xlsx and .xlsm files. Everything runs locally in your browser — the file is never uploaded.
An .xlsx or .xlsm file is really a ZIP archive of XML documents. When you “Protect Sheet” in Excel, it just adds a small <sheetProtection> tag inside the sheet's XML — it is not encryption, only a flag that tells Excel to block edits. This tool opens the ZIP in your browser, deletes those tags, and re‑zips the file. Because everything happens on your device, your spreadsheet is never uploaded to any server.
.xlsx or .xlsm workbook.No. All processing happens locally in your browser tab. The file never leaves your computer.
Yes — same ZIP structure. Macros are left untouched.
That is a different, real encryption (AES). There is no way to remove it without the correct password, so this tool detects encrypted files and refuses them rather than pretend.
Removing edit‑protection from a spreadsheet you own or are authorized to modify is a normal task — Excel itself describes sheet protection as an anti‑accident measure, not security. Only use it on files you have the right to change.
