About the JSON Formatter

What is JSON?

JSON (JavaScript Object Notation) is the most widely used data format in web APIs and software configuration. Properly formatting JSON makes it easier to read, debug, and validate data.

Features

Our tool offers formatting with 2 or 4 spaces of indentation, minification to reduce size, and validation to check if the JSON is syntactically correct, with detailed error messages.

When to use?

Use it to format API responses, debug webhook payloads, validate configuration files (package.json, tsconfig), or minify JSON before sending in requests.
