A private CSV repair tool with no upload and no subscription

I built CSV Repair & Deduper for people who receive customer or contact exports that fail imports or create duplicate records.

It detects comma, semicolon, tab, or pipe delimiters; handles quoted and multiline cells; supports UTF-8 and legacy Windows-1252 exports; and flags exact or near-duplicate rows for review. Everything runs locally in the browser, so the CSV is not uploaded.

It is USD 19 once, with no subscription. The downloaded version can be used permanently and includes version 1.x updates.

There is a sample demo and before/after example here:

Important limit: near-duplicate matches are suggestions and should be reviewed before deleting rows. Please do not post private files or customer data.

I would value one piece of feedback: is your bigger CSV problem a rejected import or duplicate records after a successful import?
