What is a JSON Formatter?

A JSON Formatter (also called a JSON Beautifier or JSON Pretty Printer) takes raw, minified, or messy JSON data and converts it into a clean, human-readable format with proper indentation and line breaks. Developers use it daily when working with API responses, config files, and database outputs.

What is a JSON Validator?

A JSON Validator checks your JSON data against the official JSON specification (RFC 8259) and tells you exactly where syntax errors are — missing commas, unclosed brackets, incorrect quotes. Instead of spending 20 minutes hunting a missing brace, paste your JSON and get instant error detection.

How to Use This JSON Formatter

  1. Paste your JSON data into the input panel on the left.
  2. Choose your indentation style — 2 spaces, 4 spaces, or Tab.
  3. Click Format to pretty-print your JSON.
  4. Click Minify to compress it for production use.
  5. Click Validate to check for syntax errors only.
  6. Use Copy or Download .json to save your output.

When Would You Need This Tool?

  • Debugging API responses from REST or GraphQL endpoints
  • Formatting JSON config files (package.json, tsconfig.json, etc.)
  • Validating data before sending to a database
  • Reading minified JSON from third-party services
  • Learning JSON structure as a beginner developer

Is My Data Safe?

Yes. All JSON processing happens directly in your browser. Your data is never sent to any server, stored, or shared with third parties.

Frequently Asked Questions

What is the difference between JSON Format and JSON Validate?

Format adds indentation and line breaks to make JSON readable. Validate checks if the JSON syntax is correct without modifying it.

Is this JSON Formatter free to use?

Yes, completely free. No signup, no login, no limits.

What indentation does this tool support?

2 spaces, 4 spaces, and Tab — select your preference before formatting.

Base64 Encoder / Decoder

New

Encode plain UTF-8 text to Base64 or decode Base64 back to text in your browser (whitespace ignored when decoding). Swap encode/decode, copy the result, or upload a file in encode mode to extract the raw Base64 payload from a data URL. Convert runs client-side only.

New

Beautify CSS, SCSS, or Less with Prettier (PostCSS plugin, tab width 2 or 4, print width 100). Minify plain CSS with csso (restructure on).
