Frequently Asked Questions & Guide

What is a JSON Formatter?

A JSON Formatter is an online tool that takes raw, compact, or minified JSON text and reformats it with indentation, newlines, and spaces to make it easy for humans to read and debug.

Is my JSON sent to a server for formatting?

No. The entire parsing and reformatting process runs 100% inside your browser using client-side JavaScript. Your data remains secure on your device.

How do I fix a 'JSON parsing' error?

Double-check your keys and values. In standard JSON, all keys and string values must use double quotes (not single quotes). Ensure there are no trailing commas at the end of lists or objects.
