JSON Formatter & Validator

Clean up, format, and validate your JSON data instantly.

Why Use a JSON Formatter?

JSON that has been minified or generated by a machine is often difficult to read. A formatter adds indentation and line breaks, transforming a compact string into a human-readable structure. This tool also acts as a validator, immediately alerting you to syntax errors like missing commas or brackets, which can save hours of debugging time when working with APIs.

Frequently Asked Questions

No, formatting does not change the data or the structure of your JSON. It only adds whitespace (spaces, tabs, newlines) to make the code easier for humans to read. The data itself remains identical and will be parsed by any machine exactly the same way.

A backslash in JSON is an escape character. It is used to include special characters within a string, such as a double quote (`\"`), a newline (`\n`), or another backslash (`\\`). Our formatter correctly handles these escaped characters.

JSON is a string format for data exchange, while a JavaScript object is an in-memory data type. A key difference is that in JSON, all property names (keys) must be enclosed in double quotes, whereas in a JavaScript object, quotes are often optional.
