If you have locked an Excel sheet and can’t remember the password, it can be a frustrating experience. However, there are various ways to regain access to locked Excel sheets.
The first thing to try is to use the password that was initially set on the Excel sheet. It’s possible that it was written down somewhere or saved in a password manager. If that doesn’t work, try using a password recovery tool. There are numerous applications available online that claim to recover password-protected Excel sheets. However, be wary of downloading software from untrusted sources as they may contain malware.
Another option is to use the “Open and Repair” feature available in Excel. To do so, follow these steps:
- Open Excel and click on “File” in the top-left corner of the screen.
- Select “Open” from the file menu.
- In the “Open” dialog box, select the Excel sheet that is locked.
- Click on the drop-down arrow next to the “Open” button and select “Open and Repair”.
- Select “Repair” and wait for Excel to repair the file. Note that this method may result in data loss.
If none of the above methods work, you can contact Microsoft support for further assistance.
