# KeylessFile

> Free online tool to remove Excel sheet and workbook protection without password.

## What it does

KeylessFile removes protection from Excel files (.xlsx, .xls, .xlsm) when you forgot the password. Files are processed securely and deleted immediately after use.

## What it can remove

- Sheet protection (locked cells that prevent editing)
- Workbook protection (protected structure that prevents adding/deleting/hiding sheets)

## What it cannot remove

- File encryption (password required to open the file)
- If Excel asks for a password before showing any content, that's encryption — not protection. KeylessFile cannot help with encrypted files.

## How it works

Excel files (.xlsx) are ZIP archives containing XML files. Sheet and workbook protection is just a configuration tag in the XML — not real encryption. KeylessFile removes these tags, allowing you to edit the file again.

## Technical details

- Supported formats: .xlsx, .xls, .xlsm
- Maximum file size: 5MB
- Processing: Secure server-side, in-memory only (nothing written to disk)
- No account or registration required
