How to use this tool

Paste any JSON, choose an indent, then format. Invalid JSON shows a parser message instead of a half-written file.

Free online JSON formatter and beautifier

A JSON formatter is one of the most used daily developer tools. APIs, Laravel Eloquent toArray output, Nuxt payloads and Docker logs all emit compact JSON that is hard to read in one line. This page pretty-prints or minifies JSON entirely in your browser so tokens, config files and error bodies never leave the device.

Paste a document, choose two spaces, four spaces or minify, then copy the result. Invalid input shows the native parser message instead of a silently broken file. That is safer than “fixing” JSON by guessing where a comma is missing.

Use this formatter when you review webhook payloads, compare fixture files or prepare samples for a bug ticket. Pair it with the JSON validator when you only need a pass/fail check, or with the YAML converter when a CI file should stay in YAML.
