More VBA Code to Remove Worksheet Edit Protection

The Tip of the Night for May 20, 2020, discussed how to use Visual Basic code to remove the protection for a worksheet in Excel. This night's tip demonstrates alternate vba code to edit protection placed on an Excel workbook.


This code successfully removed the protection for a worksheet protected with a fairly strong password: GiraffeY2K2020 - in just a few seconds.


1. Open a blank Excel workbook, and as always press ALT + F11 to open Visual Basic. Insert the below code in a new module in the project list on the left.


2. Press play to run the macro. You will be prompted to select the Excel file to process.


3. The macro will create a copy of the file in its original directory and append the date and current time to the end of the file.


When the processing is done, any restrictions on the file should be removed. As the below screen grab shows, the macro works quite rapidly.





See the version of the code posted here, by Excel Off the Grid.
