We are updating the Spreadsheet Upload files. One change we've made is to protect the spreadsheet so that users can't inadvertently delete columns or make other changes that will cause a problem.
We've heard from several users who don't like this change. We are considering the pros and cons of reversing this change.
In the meantime, you can reverse this protection in Excel:
--go to the Worksheet that you want to unprotect
--click on the Review tab on the top
--click "Unprotect Sheet"
Let us know what you think about this issue. Should we reverse the protection? Is it a good idea for some users? Or just creating an extra step? Send your feedback.
