JSON Beautifier & Formatter
Easily format and prettify your JSON data with a single click.
Easily format and prettify your JSON data with a single click.
The JSON Beautifier makes JSON instantly readable by applying consistent indentation, line breaks and optional colorization so you can inspect data quickly. Ideal for developers, technical writers and anyone who receives dense or minified JSON, the beautifier transforms compact payloads into an indented, human‑friendly format with configurable indentation size.
You can paste or upload JSON, tweak formatting options, and copy the formatted result back into your editor or documentation. Because formatting is done client‑side, your data remains private and rendering is instant. The beautifier also pairs well with the validator — format then validate — and with the minifier for the reverse workflow. Use it to prepare example payloads for docs, debug API responses faster, or review complex nested objects with clarity. Try pasting a minified JSON to see how it expands into a readable structure.
