Recover a Forgotten Excel Password (Free to Check)
Updated July 2026 • 5 min read
Excel is asking for a password before it will show a single cell of your spreadsheet, and you do not have it. Here is the good news and the bad. If the file opens but a sheet or the workbook is locked for editing, that is just a flag you can strip off for free in seconds. If Excel will not open the file at all, the workbook is encrypted, and an encrypted file can only be recovered, not unlocked. This guide shows you which one you are facing, what to try that costs nothing, and how recovery works if it comes to that.
First: is your Excel file encrypted, or just protected?
The two look alike but are completely different. If the spreadsheet opens and only certain cells, sheets, or the workbook structure are locked, that is sheet or workbook protection, and it can be removed instantly and for free. If Excel shows the password box on the 'enter password to open' dialog before you can see any data, that is open-password encryption, which has to be recovered.
Sheet or workbook protection (removable, free)
Your spreadsheet opens fine, but some cells will not edit, sheets are locked, or the workbook structure is protected. That is only a flag. You can remove it instantly and for free, right in your browser, with no password needed.
Unprotect it for freeOpen-password encryption (recover only)
Excel shows the password box the moment you open the file and will not reveal a single cell without it. The whole workbook is encrypted (AES, on every version since Excel 2007), so there is no flag to delete. The password itself has to be found, which is what the steps below cover.
Recover a forgotten Excel open-password: try these first
These cost nothing and solve most real lockouts. Work through them before paying for anything.
- Retry the password carefully. Excel passwords are case-sensitive. Check Caps Lock, your keyboard language, and a stray trailing space, and try your usual passwords and close variations. Excel's message, 'The password you supplied is not correct', just means keep trying candidates.
- Ask whoever set it. If the workbook came from a colleague, a client, or an old export, the person who saved it chose the password. One message is faster than any tool.
- Check OneDrive or SharePoint version history. If the file syncs to OneDrive or SharePoint, open its version history. An earlier revision may pre-date the password, and you can restore that copy unencrypted.
- Look for an unlocked copy. A pre-lock version in a backup, an email attachment, or a synced folder sidesteps the password completely.
Still locked out? How Excel password recovery works
When the password is genuinely lost and there is no earlier copy, the only route left is a password search: trying large numbers of likely passwords against the file's encryption. Our recovery does this without your spreadsheet ever leaving your browser. Only the file's lock fingerprint, a hash that reveals nothing about your data, is sent to a cloud GPU, which works through common passwords and realistic variations. It is free to check, and there is no charge unless it actually finds the password. A weak or common Excel password often falls in minutes, while a long, random one may never be found, so treat it as a strong maybe, not a guarantee. It supports Excel 2007, 2010 and 2013 or newer.
What to expect from recovery
Your .xlsx never leaves your device. Only its lock fingerprint is sent, so we never see the spreadsheet or its contents. Short or common passwords can fall fast, while a long, random one may be impractical to find, which is the encryption doing its job. Steer clear of any service that asks you to upload the whole encrypted file, because that is neither necessary nor safe.
Check your Excel file freeFrequently asked questions
Can I remove a forgotten Excel open-password for free?
You cannot remove it, because an open-password encrypts the whole workbook and there is nothing to strip out. You can try to recover it. Our tool works out the password by trying likely candidates on a cloud GPU, and only the file's lock fingerprint is ever sent, never the spreadsheet. It is free to check and finds many common passwords, though a strong, random one may never be recovered. Avoid any site that asks you to upload the whole encrypted file.
How is this different from unprotecting an Excel sheet?
Sheet and workbook protection only restrict editing, so the file still opens without a password and the restriction can be removed instantly and for free. An open-password stops the file from opening at all, which is encryption, and encryption can only be recovered.
Which Excel versions can be recovered, and how long does it take?
It works on Excel 2007, 2010 and 2013 or newer encryption. A weak or common password can fall in minutes, while a long, random one may be impractical to find. There is no charge unless the password is actually recovered, so it is free to check either way.
