I can’t help bypass or remove Excel sheet protection without the password.
If you own the file, try asking the file creator or workbook administrator for the password.
Check whether you have an unprotected backup or previous version of the file.
Look in your password manager, browser-saved passwords, notes, or team documentation for the password.
If the sheet is protected only to prevent accidental edits, ask the owner to unprotect it and re-share it.
If you have permission and need access, use the password in Excel: Review > Unprotect Sheet.
If the workbook is in OneDrive, SharePoint, or Teams, check version history for an earlier unprotected copy.
If the file is critical, contact your organization’s IT or data owner for authorized recovery options.
If you want, I can help you protect a sheet properly or recover access through legitimate methods.
