CSV Repair & Deduper
Clean broken and duplicate CSV rows offline—$19 once
Repair malformed CSV exports and review exact or fuzzy duplicates without uploading customer data. This downloadable single-file tool runs locally in your browser, detects common delimiters and encoding issues, flags uneven rows, and lets you review, edit, undo, and export every change. Unlike automatic “black box” cleaners, near matches remain suggestions for human review. $19 once, no subscription.
Hi Product Hunt — I built CSV Repair & Deduper for people cleaning CRM contacts, ecommerce orders, and other business exports who don’t want to upload customer data to a server.
It’s a downloadable single HTML file that runs locally in your browser. It can:
1.detect comma, semicolon, tab, and pipe delimiters
2.handle quoted and multi-line cells
3.identify common encoding issues
4.flag uneven rows
5.separate exact duplicates from adjustable near-match suggestions
The review-first workflow is intentional: similar records are suggestions, not automatic deletions. You can inspect and edit rows, undo changes, and export the cleaned file locally.
It’s $19 once, with no subscription. The downloaded version keeps working permanently and includes all version 1.x fixes and improvements.
There are also 28 free CSV-cleanup guides with manual Excel and Python methods:

Honest current state: production and checkout are live, but I don’t yet have evidence of demand for the $19 offer. I’d especially value feedback on the offline/privacy positioning, the review-first workflow, and the price.
