Some days it feels like all I do is convert files from one ill-defined data format to another.
And for those thinking about storing their massive dataset in Excel, let me give you some advice_ Don't.
If you don't know why this is a bad thing, find yourself a bioinformatician and ask. Be sure to observe the look of horror on their face when you show them your workbook with 16 different sheets, all cross-referenced and full of arcane formulas that you'll never be able to decipher. For bonus points, store multiple types of data in the same text field and don't bother using a consistent format. (It's okay because, I know that FM85436 is the same thing as 98TBE3)
Sigh. . .
