Mats – We are aware of this issue. It will be fixed in the next version. The issue is that when you copy/paste directly from Excel, each cell adds a hidden t (tab char). BatchPatch used to auto-remove the t until the most recent version when we made a slight change to the parsing, but forgot to deal with the t from Excel, not realizing that users were so frequently copying directly from Excel. The next version will remove the t once again.
