I followed the instructions to ONLY have the five columns--i opened the "raw" file from Coinbase in Excel, deleted the "extra" columns, put them in this order EVEN THOUGH the instructions say they don't have to be
Purchase Date,Cost Basis,Date Sold,Proceeds,Currency Name
still didn't work.
BUT, i opened the file in notepad and deleted the last line which was blank, SAVED as .CSV. This seems to have resolved the "Your import was unsuccessful" error.
Seems like a boatload of workaround, but seems to have worked.
