things take a turn for the worse.

workbook.xlsx, change it to workbook.zip
Step 3: Extract the contents of the zip file.
Step 4: Go to the extracted files and
navigate to the xml for the target sheet
(found in the ‘xl\worksheets’directory)
Step 5: Open the target sheet’s xml
document.You should right click and select
edit. now it will open and you can edit it.
Step 6: Find the ‘workbookProtection’ tag
and remove the entire line.
It would be something like <Workbook
protection lockstructure= "1"/>
Remove that entire line. (only that line)
Step 7: Save the edited xml document and
replace the old xml document found in the
original zip file.
Step 8: Change the extension back to xlsx.
