CSV Rescue Kit

CSV Rescue Kit cleans CSV in the browser: trim fields, remove empty rows, deduplicate exact rows, and export CSV or JSON. CSV content is processed locally. The account-free public demo supports up to 100 data rows and UTF-8 inputs up to 5 MiB. The proprietary offline HTML kit costs $19 USD once and includes perpetual personal and commercial internal-team use. Spreadsheet-safe export prefixes formula-prone text with an apostrophe and changes those values, including negative numbers; review exports before use. Originally built with AI assistance; no AI inference is needed to process files.
