MICROSOFT EXCEL. You edit my data. Did you consider that maybe, MAYBE, "8-16" wasn't a date and that you shouldn't convert it to August 16th? Or perhaps, not edit the DATA so that I could choose to reformat the cell to "text" and get back to 8-16 instead of 42853? Where the HELL did 42853 come from anyways? Also, when I save you as a CSV, I expect a line break inside a cell to be removed or converted. I don't expect to see two 8-column lines in my 16-column CSV file.
HATE.
