How JSON Formatting works

The JSON Formatter parses your raw JSON input, validates its syntax, and re-formats it with proper indentation for readability. It can also minify JSON by removing all whitespace.

Avoid mistakes

Common mistakes

A few things that can lead to misleading results or poor decisions.

JSON (JavaScript Object Notation) is a lightweight data interchange format. Keys must be double-quoted strings, and values can be strings, numbers, booleans, null, arrays, or objects. Trailing commas are not allowed.
