About the JSON Beautifier

Turn compact or single-line JSON into indented, readable structure for API responses, webhooks, configuration files, logs, and debugging sessions.

Format JSON before you inspect or ship it

Beautifying expands minified payloads so nested objects, arrays, keys, and values are easier to scan. Paste text or upload a .json file, then copy or download the formatted result.

Explore structure in the JSON Viewer, confirm syntax with the JSON Validator, shrink output with the JSON Minifier, export rows via JSON to CSV, or format markup with the XML Beautifier.

Paste or upload JSON

Start from the text editor or a JSON file when you need readable indentation without configuring an IDE formatter.

Inspect API and webhook payloads

Expand response bodies and event payloads before tracing nested fields or sharing an example with another developer.

Copy or download formatted output

Move cleaned JSON into tickets, docs, or editors, or save a file for the next handoff.
