Make JSON readable
Pretty-print compact JSON so API payloads, MCP configs, and manifest-like data can be reviewed.
Utilities
Format JSON for humans and agents
Validate and pretty-print JSON so configuration snippets, MCP examples, and API payloads are easier to review.
Processed on the server.
Do not paste passwords, tokens, or private keys.
Results will appear below the editor after you run the tool.
Catch invalid syntax
The server decodes the JSON and returns a clear error when the input is malformed.
Useful for automation
Readable JSON makes it easier to debug agent configs, CLI responses, and webhook payloads.
How to use JSON Beautifier
Pretty-print JSON so nested API payloads, manifests, and MCP configuration are easier to audit.
Paste JSON
Add the payload, config, or response body you want to inspect.
Beautify safely
StaticX validates and formats the JSON on the server.
Copy reviewed output
Use the formatted result in docs, tests, or local config examples.
Readable JSON prevents quiet automation mistakes.
A missing comma or wrong nesting level can break an MCP config, API request, or deployment script. Pretty formatting makes those mistakes visible.
Do not paste live secrets into public tools. Use placeholders when formatting examples that will be shared.
Readable JSON habits
Great for MCP config
Review nested mcpServers blocks and environment placeholders before copying them into docs.
Strict JSON only
Comments, trailing commas, and JavaScript object syntax are not valid JSON.
Pairs with validator
Use JSON Validator when you only need a pass/fail syntax check.
Questions about JSON Beautifier
Short, practical answers for using this page safely.
Does the beautifier accept JSON with comments?
No. JSON comments are not valid JSON and should be removed before formatting.
Can I format MCP configuration?
Yes, but use placeholder tokens rather than real API tokens.
What happens with invalid JSON?
The tool returns an error explaining where parsing failed.
