Choose an Excel workbook
Select one .xlsx or .xlsm file.
Use this tool only with workbooks you own or are authorized to modify.
It removes sheet and workbook editing protection. It cannot remove a password required to open the file, file encryption, or VBA project protection.
What this Excel protection remover changes
An XLSX or XLSM workbook is a ZIP package containing XML files. Excel records sheet editing protection in sheetProtection elements and workbook structure protection in a workbookProtection element. This tool removes those elements and writes a new workbook.
It does not recover a password or try password combinations. Cell values and other package entries are copied without changing their content. Use it only for a workbook you own or have permission to modify.
The workbook stays on your device
The workbook is read and rebuilt by code running in the browser. There is no server-side conversion step:
- The XLSX or XLSM package is opened locally in the browser.
- The static page does not send the workbook to a conversion service.
- The source code is available under the MIT License.
- After the page has been cached, the tool can run offline.
You can verify the behavior in the browser Network panel while processing a workbook. Read the source.
How to remove the protection
-
Choose one workbook
Select an .xlsx or .xlsm file, or drop it on the page. The workbook must already be openable without an opening password.
-
Review the result
The tool removes sheetProtection and workbookProtection elements. It lists the sheet names whose protection was removed and reports workbook structure protection separately.
-
Download the new workbook
When protection is found, the rebuilt workbook downloads as a file ending in -unlocked.xlsx. The original file is not overwritten.
FAQ
Is my Excel file uploaded?
No. The workbook is read and rebuilt in your browser. The page has no server-side conversion endpoint, and the source code is available for inspection.
What kinds of Excel protection does this remove?
It removes sheet editing protection stored in sheetProtection elements and workbook structure protection stored in a workbookProtection element. It does not edit cell contents.
Can it remove a password required to open the file?
No. A file protected by an opening password is an encrypted CFB container rather than an open OOXML ZIP package. This tool cannot open or decrypt that container.
Does it crack or reveal the sheet password?
No. It does not decrypt, recover, or display a password. It removes the XML protection element from an already-openable workbook.
Does it remove VBA project protection?
No. VBA project protection is outside this tool’s scope. The tool accepts XLSM input but does not modify or unlock the VBA project.
What happens if the workbook has no protection?
The result states that no sheet or workbook protection was found. No download starts in that case.
Does it work offline?
Yes. The site is a PWA; after its files have been cached, workbook processing can run without a network connection.
