About mapping CSV columns
Imports usually expect specific column names in a specific order, but exports rarely match. Rather than editing a spreadsheet by hand, this mapper lets you rename headers, uncheck columns you don't need, and produce a clean CSV that fits the target schema.
It parses your CSV correctly (quoted fields and all) and rebuilds it from your choices, entirely in your browser so the data stays private.
