JSON tools

Utilities for reading and formatting JSON data.

Use these pages when logs, API responses, or config files arrive as raw JSON and you need readable formatting, a smaller payload, or a browsable tree.

They are built for quick copy-and-paste: paste your text, run the action, then copy or inspect the output in the same tab.

JSON beautifier

Expand minified JSON into clean indentation so keys and arrays line up.

Grab the formatted version in one click for tickets, docs, or chat.

Built for the moment you need structure, not a lecture.

JSON beautifier

Pretty-print JSON in your browser—no account, no upload.

Expand minified JSON into clean indentation so keys and arrays line up.
Spot bad JSON early—the parser complains with a plain error, not a blank panel.

JSON minifier

Remove extra whitespace from JSON in your browser—no upload.

Collapse whitespace and line breaks into one compact line.
Parse checks happen before output—bad JSON returns an error, not garbage.
Everything runs in your browser tab—nothing is sent to our servers to minify.

JSON tree viewer

Turn raw JSON into an expandable tree in your browser—no upload.

Visualize objects, arrays, strings, numbers, and booleans in a nested tree.
Collapse noisy branches and expand only the path you care about.
Parsing happens in your tab; your JSON is not uploaded to our servers.

JSON to Java

Paste a JSON object, name the root record, and copy Java 16+ records—no upload, no account.

Emit Java records with fields inferred from strings, numbers, booleans, objects, and arrays.
Nest record types for nested JSON objects; arrays become List types with imports when needed.
Your JSON never leaves the browser—we do not send it to a server to generate Java.
