Hey Product Hunt 👋 I built this because I kept manually converting and cleaning spreadsheets for small projects — same repetitive steps every time. This tool handles the conversion (CSV/Excel/JSON) and basic cleaning (duplicates, empty rows, whitespace) in one command, no need to upload your data anywhere. This free edition handles up to 200 rows per file — great for testing it out. Would love to hear what data-cleaning pain points you run into most!

Finally a data cleaner that doesn't try to ship my CSVs off to some server. Loved the interactive mode; it figured out the duplicates in my messy export way faster than I expected.
