Re: A plague on Excel's house!
the silent conversion of large integers into exponentials
You forgot the important bit (sic): converted and truncated: Excel is limited to 15 digits of precision unless you keep it as text. Had this recently relating to customer and card numbers. Oh, how we laughed…
Still, as interchange format I see fewer problems with Excel because you do have typing and can add data validation, which generally leads to less of a mess than if you give someone a CSV…
