0 Worksheets Found.

Aug 15, 2013 at 7:02 PM
I recently downloaded Test Case Migrator V1.2RTM to get tests into Test Manager from an Excel spreadsheet. However, whenever I select a .xlsx created in Excel 2007, I get the error "0 worksheets found."

I have tried downloading the example spreadsheets, and I have also tried downloading V1.1 and I still get the same error. I'm using Test Manager 2012 to connect to a TFS 2012 project. Any suggestions for what might be going on and how to fix this?
