Free CSV tools — no signup, no upload required.
Most CSV utility sites paywall the useful features, require an account, or upload your file to their server. The tools below run in your browser. No login, no paid tier — ad-supported is the entire business model.
Honest about what we are.
We don't sell premium tiers or charge for the converters. Two ad slots on the page pay for hosting; everything else is free. That's the deal.
Every tool below — free, no signup.
Common questions.
-
·
Are there any hidden paid features?
No. There is no paid tier on the site. The roadmap may eventually include one for very specific power-user features, but the existing tools above are free.
-
·
Do I need to give an email address?
No. There is no signup or login. There is no email field anywhere on the site.
-
·
Why is it ad-supported then?
Two AdSense slots on most pages pay for the domain and hosting. We were honest about this rather than pretending the site runs on goodwill.
-
·
Can I block the ads?
Yes — the tools work fully without them.
