Why two products, one company
openbigcsv.com is the front door. Row Zero is the destination.
This site solves one narrow problem for free, forever: opening a CSV that's too big for the spreadsheet software you already have. Row Zero is the full product behind it, for when a one-off file becomes a recurring workflow.
