When I make an excel-sheet with EPPlus, using a template, Excel 2010 cannot open the file because of corrupted data.
I made the same sheet in Excel and compared it to the sheet generated by EPPlus (after unzipping). The main difference I found was that the directory _rels was missing on the root (next to xl, docProps and [ContentType].xml, not the one in the xl directory). When I add the directory with the file '.rels' and zip it again, the file opens nicely in Excel
