🧹 Messy Data Cleanup
Paste messy data (CSV/list/table) and get it cleaned — standardized formats, fixed typos, normalized labels, flagged duplicates. Values and IDs are never invented or changed, only formatted.
- Never invents data. Numbers and IDs are only reformatted — blanks stay blank, nothing is guessed or filled in.
- Full audit trail. Every fix is listed, and anything ambiguous is flagged for your review instead of silently changed.
- Paste back or export. Output keeps the same shape as your input, so you can copy it straight back or download an Excel/CSV.
