The spreadsheets are locked - how do I filter, sort, insert, delete...?

The Spreadsheet Upload files are in "protect" mode so that users can't inadvertently delete columns or make other changes that can cause a problem.

If you want to change this setting in Excel to filter, sort, insert, delete, etc: 

1. Go to the Worksheet that you want to unprotect
2. Click on the Review tab on the top
3. Click "Unprotect Sheet"
