Format Validation

This subcategory offers seven validators for checking the shape of common strings. XML Validator, URL analyzer and Domain Validator are included. Developers, testers and administrators can check an entry or diagnose an address. The seven validators are free, require no account, and processing happens in the browser.

Start from the format to check. XML Validator inspects the structure and root of a document. URL analyzer breaks down an HTTP or HTTPS address, while Domain Validator checks the syntax of a name. Email Validator, IPv4 Validator and UUID validator target precise strings. Password analyzer assesses strength criteria locally. Choose according to the data you submit.

How to use

  1. For a markup document, start with XML Validator and inspect structure and root before other checks.
  2. For an address, use URL analyzer, then Domain Validator to separate the full address from the name alone.
  3. For a precise string, choose Email Validator, IPv4 Validator or UUID validator according to the submitted format.
  4. For local strength, finish with Password analyzer and read the resulting criteria before changing any password.

Frequently asked questions

Does XML Validator repair a malformed document?

No. It validates the structure and inspects the root, but it does not fix missing or unclosed tags. The message helps locate the problem. Then correct the file with a suitable editor before submitting it again.

Does Password analyzer send the entered value anywhere?

No. It evaluates strength criteria locally in the browser. The password does not have to leave your device for this analysis. Still avoid reusing an important password in a test context.

What is the difference between URL analyzer and Domain Validator?

URL analyzer breaks a full address into components. Domain Validator focuses on the syntax of the domain name. Use the first to understand an address and the second to check a name alone.

Can I chain URL analyzer and Domain Validator?

Yes. URL analyzer breaks an HTTP or HTTPS address into components. Domain Validator then checks the syntax of the extracted domain name. This sequence helps distinguish a full-address issue from a name issue.

Does Password analyzer replace the other validators?

No. Password analyzer evaluates strength criteria locally, while Email Validator, IPv4 Validator and UUID validator check precise formats. Use it for a password and the others according to the string you need to check.
