Change Workbook Password

If the password to open or write an Excel workbook has changed, you can update it in this dialog.

Best practice

Always use the Test new password settings option to avoid entering wrong passwords which may lead to failed updates later.
Add Excel Workbook

If the workbook does not require open or write passwords simply disable the respective toggle or click the Remove button. If the workbook requires a open or write password enable the respective toggle and enter the password.

Enable the Test new password settings toggle to test if the password is correct when clicking OK. If this toggle is disabled the password will be saved but not tested. If you entered a wrong password this may lead to failed updates later.
