Spreadsheet Cleaner vs ChatGPT

CleanMySheet, a rule-based CSV cleaning tool, argues it outperforms ChatGPT for spreadsheet cleanup because it applies named, reversible operations with per-cell explanations and a downloadable quality report, whereas ChatGPT may invent cells and requires an upload. The tool optionally uses Anthropic's Haiku model only as a type hint on ~15 sample values per ambiguous column, keeping full rows local.
