JSON Formatter & Validator

A powerful, browser-based utility to format, minify, and validate JSON data with optional schema support.

🚀 Why Use JSON Formatter & Validator?

Handling raw JSON can be cumbersome. Whether you're debugging API responses, cleaning up configuration files, or ensuring data integrity, this tool provides a fast and secure way to manage your JSON structures directly in your browser.

Developer-Centric Features

  • Customizable Indentation: Adjust spacing from 0 to 8 spaces to match your project's style.
  • Key Sorting: Automatically sort object keys alphabetically for better readability and comparison.
  • Schema Validation: Go beyond syntax checks by validating your JSON against a custom JSON Schema (Draft 7+).
  • Local History: Quickly access your last 10 formatting sessions, stored securely in your browser's local storage.

🛠️ Key Features

  • Beautify & Minify: Switch between human-readable formatted JSON and compact minified versions instantly.
  • Real-time Validation: Detect syntax errors immediately with clear error messages and line indicators.
  • Advanced Schema Support: Uses the Ajv library for high-performance JSON Schema validation, providing detailed error reports for non-conforming data.
  • Privacy-First: All processing is performed locally in your browser. Your data never leaves your machine.
  • One-Click Copy: Easily copy the processed output to your clipboard for use in your IDE or documentation.

📖 How to Use

  1. Input JSON: Paste your raw JSON data into the "Input JSON" area. A sample is provided by default to help you get started.
  2. Optional Schema: If you need to validate against a specific structure, paste your JSON Schema into the "JSON Schema" section.
  3. Configure Options:
    • Use the Indent Size slider to set your preferred spacing.
    • Toggle Sort Object Keys if you want a deterministic order for your object properties.
  4. Process:
    • Click Format JSON to beautify the input using your selected options.
    • Click Minify JSON to quickly remove all unnecessary whitespace (ignores sorting options).
    • Click Validate to check syntax and schema compliance without changing the output window.
  5. Review & Copy: View the formatted or minified results in the "Formatted JSON" window and use the Copy Output button to save it.
  6. History: Click on any previous entry in the "Formatting History" section to reload it. You can also Clear History to remove all stored entries.
