Batch Validator
Paste many values (one per line) to check whether it is valid — complete with the reason if it is invalid and a component breakdown if it is valid. Everything is processed on your device.
Everything runs in your browser. Your data is never sent to our servers.

About Batch Validator
Batch Validator runs ONE chosen validator (URL, email, IP, UUID, credit card, and more) against each input line, then summarizes how many are valid, warnings, and invalid — and lists the failed lines.
Ideal for cleaning a list: paste hundreds of email addresses or URLs and instantly see which ones are problematic.
FAQ
Is my data sent to a server?
No. All validation runs in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
How is this validator different from a parser or formatter?
A validator answers one question: is this input correct/valid? It returns a valid/invalid badge with the reason. A parser breaks input into its components, and a formatter tidies its layout. Use a validator when you just need to confirm something is sound before using it.
