CSV Cleanroom
Clean messy CSVs locally—no uploads or subscriptions
CSV Cleanroom is a private, offline CSV cleaning utility. It detects delimiters, normalizes headers, trims whitespace, removes blank and duplicate rows, infers column types, and exports Excel-friendly UTF-8 CSV files. Everything runs in your browser, so files never leave your device.
I built CSV Cleanroom for the annoying cleanup that repeats whenever a CRM, payments tool, or survey platform exports a messy CSV. The goal was deliberately narrow: one offline file, no telemetry, no signup, and a result you can inspect before exporting. The live demo is limited to 25 rows; the $12 version handles full files and exports the result. I’d especially value feedback on delimiter handling and the cleanup defaults.
