Is this Excel password remover online free?

Yes, it's 100% free. There is no signup, no watermark, no file limit, and no premium tier. The remover runs entirely in your browser, so it also works offline once the page has loaded.

How do I remove a password from an Excel sheet without knowing it?

Upload your .xlsx file above. The tool scans the workbook, deletes the sheet protection and workbook protection records, and gives you an unlocked copy to download - no password required. It works because Excel stores sheet protection as a removable flag inside the file, not as encryption.

How does the Excel password remover work?

An .xlsx file is a ZIP archive of XML files. Sheet protection is saved as a element containing a password hash that Excel checks only when you try to edit. This tool removes those elements (and for workbook structure locks) from the XML, so nothing is cracked or guessed - the lock is simply taken off.

Can it remove the password required to open an Excel file?

No. If Excel asks for a password before the file opens at all, the file is encrypted, and the data cannot be read without the correct password. This tool removes editing restrictions (sheet and workbook protection), which is what most locked spreadsheets use.

Does it work on .xlsm and old .xls files?

Macro-enabled .xlsm workbooks are fully supported - the unlocked copy is returned as .xlsm with its macros intact. Legacy .xls files (Excel 97-2003) use a different internal format, so convert them to .xlsx first with our XLS to XLSX converter - sheet protection does not block reading, so the converted copy is editable.

Is my Excel file uploaded to a server?

No. All processing happens entirely in your browser using JavaScript. Your file never leaves your device, which makes this safe to use even for confidential spreadsheets.

Is there a file size limit or daily limit?

No. Because the file is processed on your own device rather than a server, there are no size gates, daily quotas, or premium tiers. Most upload-based removers cap free files at a few megabytes or charge for anything larger; this tool handles any .xlsx your browser can hold in memory, as many times as you like.

Is this legal to use?

Only use this tool on files you own or have permission to modify - for example, spreadsheets where the password was lost or the author has left. Removing protection from files you don't own may violate terms of service or laws in your jurisdiction.

How to Remove a Password from an Excel Sheet Online, Free

Upload your .xlsx file - Drag and drop or click to browse for your Excel file. It is processed locally, never uploaded.
Automatic removal - The tool detects every protected sheet and any workbook structure protection, then strips the protection records. You don't need to know the password.
Download - Get your unprotected file, ready for editing in Excel, Google Sheets, or LibreOffice.

Why This Works Without the Password

An .xlsx workbook is really a ZIP archive full of XML files. When an author protects a sheet, Excel doesn't encrypt anything - it just writes a <sheetProtection> element (containing a hash of the password) into that sheet's XML, and refuses to let you edit locked cells while the element is present. Workbook structure locks work the same way via a <workbookProtection> element.

This Excel password remover opens the file in your browser, deletes those protection elements, and repackages the workbook. Nothing is cracked, guessed, or brute-forced - the lock is simply taken off. That's why it is instant even for large files, and why it works when the password has been long forgotten.

Sheet Protection vs. File Encryption

Sheet protection (supported) - You can open the file, but cells, formatting, or structure are locked for editing. This is what most "password-protected" spreadsheets use.
Workbook structure protection (supported) - You can't add, delete, rename, or reorder sheets.
File-open encryption (not supported) - Excel asks for a password before showing anything. The file contents are genuinely encrypted, and no online tool can honestly remove that without the password.

A quick test: if you can open the workbook and see your data but can't edit it, this tool will unlock it. If Excel demands a password just to open the file, it's encrypted.

How This Compares to Other Excel Password Removers

Most tools that rank for "excel password remover" upload your spreadsheet to a server before touching it. Here is how the approaches differ:

Tool	Where your file goes	Approach
ExcelTool.io (this page)	Nowhere - processed in your browser	Free, no signup; removes sheet and workbook protection instantly, without the password
Aspose Unlock	Uploaded to Aspose servers and retained there temporarily	Free tier with sign-in and plan limits for larger files
GroupDocs Unlock	Uploaded to GroupDocs servers and retained there temporarily	Free, but you must already know the password to remove it
Desktop password-cracking suites	Stays local, but requires installing software	Brute-force file-open encryption; slow, paid, and never guaranteed

Competitor descriptions last checked 2026-07-17 against each linked page; see those pages for current limits and pricing.

The cracking suites solve a different problem: file-open encryption. If your file opens fine but won't let you edit - the far more common case - there is nothing to crack, and this free in-browser remover unlocks it instantly.

Have a Protected .xls File?

Modern .xlsx and macro-enabled .xlsm workbooks work directly. Legacy .xls files (Excel 97-2003) use a different internal format, so run those through our XLS to XLSX converter first. Sheet protection never blocks reading, so the converted .xlsx copy comes out editable.

Limitations and Fair Use

.xlsx and .xlsm only - Convert legacy .xls files to .xlsx first
Not for encryption - Files requiring a password to open cannot be processed
Legal use only - Only use on files you own or have permission to modify

Test Excel Protection Safely

Want to see exactly what this remover does before trusting it with a real spreadsheet? Use our published test workbooks - invented data, CC0-licensed, with SHA-256 checksums and expected results in the sample Excel files lab:

Sheet-protected workbook - both worksheets locked with the public password "excel123"; the remover unlocks them without it.
Structure-protected workbook - sheets cannot be added, deleted, or renamed until the lock is removed.
Macro-enabled .xlsm fixture - not protected; shows the remover accepts .xlsm files and reports honestly when there is nothing to remove.

A file-open-encrypted fixture is deliberately not published: real encryption cannot be removed without the password, and the lab page explains why. Educators and support teams are welcome to link or embed these fixtures - no attribution required.
