CSV Dedupe & Cleaner Pro

Clean list after list without redoing the setup

The free CSV Dedupe & Cleaner handles one file at a time and up to 100,000 rows. Pro is for people who clean exports every week: merge several files at once, catch near-duplicates such as typos, and reuse the exact same rules with one click.

$24 one-time payment

Pay once, keep Pro. Batch files, fuzzy matching, saved recipes and no row limit.

Get Pro

Secure checkout by Stripe, sold through Link. Sales tax or VAT is added at checkout where it applies. No subscription, no renewal. Your data stays in your browser either way.

What Pro adds

  • Batch files. Load several CSV exports at once; columns are matched by name and duplicates are removed across all files.
  • Source column. Optionally add a column that shows which file each row came from.
  • Fuzzy matching. Catch near-duplicates such as "Jon Smith" and "John Smith" with an adjustable similarity threshold.
  • Saved recipes. Store your match columns and cleanup rules by name and apply them to the next export instantly.
  • No row limit. Process files beyond 100,000 rows; the only limit is your device memory.

Activate your license

Right after checkout you come back to this page and Pro switches on automatically. You also receive your license key by email. To use Pro in another browser, enter the key here once. The key is stored in this browser's local storage and nowhere else on your device.

Before you buy

Pro starts right after payment. The purchase is processed by Link, the merchant of record operated by Stripe: Link sells the license to you and handles payment, taxes, billing questions and refunds under its own terms, which you see and accept at checkout. We provide the Pro features and support. Details are in our Terms.

Does Pro upload my data?

No. Pro features run in your browser exactly like the free tool. Only the license check contacts our server, and it sends the license key, nothing else.

Can I use Pro on more than one device?

Yes, for your own use. Enter the same key in each browser you work with. Please do not share the key outside your business.
