SmartDataAI
Clean messy CSVs in your browser — and prove what changed
Free tools that clean CSV and Excel files in your browser. Nothing is uploaded. Remove duplicates, fix phones, dates and names, and get a log of every change. Unclear values are flagged, not guessed. Need a person? Fixed-price cleanup from $19.
I built SmartDataAI after seeing the same problem again and again: someone exports a contact list, "cleans" it with a quick script or AI, and nobody can tell what actually changed.
So the tools here do three things differently:
• Everything runs in your browser. Your file never leaves your computer.
• Every removed row and changed cell goes into a change log you can download.
• If a value is ambiguous (is 03/04 March or April?), it's flagged for you instead of guessed.
What it doesn't do: it doesn't verify that mailboxes exist, and it doesn't do fuzzy matching ("Jon" vs "John"). Those need a person, and that's what the fixed-price service (from $19) is for.
I'd love your feedback on one thing: what's the messiest file you deal with, and where do current tools let you down?

Who hunted SmartDataAI?
SmartDataAI was hunted by Juan Chen. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.

Hi Product Hunt 👋
I built SmartDataAI after seeing the same problem again and again: someone exports a contact list, "cleans" it with a quick script or AI, and nobody can tell what actually changed.

• Everything runs in your browser. Your file never leaves your computer.
• Every removed row and changed cell goes into a change log you can download.
• If a value is ambiguous (is 03/04 March or April?), it's flagged for you instead of guessed.
What it doesn't do: it doesn't verify that mailboxes exist, and it doesn't do fuzzy matching ("Jon" vs "John"). Those need a person, and that's what the fixed-price service (from $19) is for.
