In Workbench, I am not sure why, but I got this error when trying to run or preview the data from an excel file:
Input string was not in a correct format.
What does that mean?
Oh nevermind. Search for "WB4: "Input String not in correct format"?" if you want the answer. it has to do with Value calculations in WB, I think. I removed that transormation and it works fine.
