JSON Validator – Quickly Validate & Format Your JSON Online 🛠️

Working with JSON manually can be tricky — a missing comma or bracket can break your application.

That’s why I built JSON Validator — a free, browser-based tool to validate, format, and prettify JSON instantly.


Features

  • Validate JSON – Catch errors instantly
  • Prettify JSON – Make it readable and structured
  • Minify JSON – Reduce size for production
  • Free & Browser-Based – No installation or signup required

How It Works

  1. Paste your JSON into the input box.
  2. Click Validate to check for errors.
  3. Format it nicely using Prettify or Minify for production.

Who Can Benefit?

  • Frontend developers debugging APIs
  • Backend developers validating server responses
  • Anyone working with JSON data in their projects
