Comma separated values: the great equalizer of the structured data universe. Whether you're importing or exporting, you can always count on the venerable CSV as a supported format.
You—navigator of numbers, commander of cohorts, parser of particulars—know how to squeeze every last drop of insight from a data set. Pivot this, filter that, validate those. Whether VLOOKUP is your flavor or you live that INDEXMATCH life, this is the sticker that says, "I know my way around a goddamn spreadsheet."
