"Hey Product Hunt! 👋
I built Rightrow because messy spreadsheet data constantly breaks downstream pipelines. Inconsistent international date formats (DD/MM vs MM/DD), dirty currency symbols, trailing whitespace, and duplicate emails ruin CRM imports and reporting.
Most 'AI' data cleaners hallucinate or change values unpredictably. Rightrow takes the opposite approach: it’s built on a vectorized, 100% deterministic engine (Polars) with an exact audit diff. It’s also strictly non-destructive, it never overwrites your original data and writes clean records to a separate dedicated tab.
Rightrow is available as a web app (upload CSV) and as a Google Sheets add-on.
I’d love to hear your feedback on the cleaning rules, diff viewer, or what integrations you'd like to see next!"
