Formatter
Paste raw JSON, open a local file, and clean up payloads quickly when you need readable output, fast validation, and a tree view for nested data.
Input JSON
Paste JSON, open a local file, or load a sample payload before formatting or validating.
Formatted output
Review the cleaned result, switch to tree view for nested data, then copy or download it.
How to Use This JSON Formatter
Use the formatter as a quick cleanup workflow: paste the JSON, validate it immediately, and switch to the view that helps you inspect or share the payload more easily.
Paste raw JSON or load a sample
Drop in an API response, config blob, event payload, or any other JSON string you want to clean up and inspect.
Check validity immediately
The tool parses the input as you type so you can spot broken commas, quotes, brackets, or invalid structure without guessing.
Switch between readable views
Use the formatted code output for editing and copying, or move to the tree view when you want to inspect nested keys more quickly.
Copy, download, or minify the result
Once the payload is valid, you can copy the cleaned output, download it as a JSON file, or minify it again for transport or storage.
When This Tool Is Most Useful
JSON formatting helps most when you are dealing with payloads that are valid but hard to read, or payloads that might be broken and need a fast validation check before you move on.
API response inspection
Format minified responses so nested objects, arrays, and missing fields are easier to read during debugging.
Config and data review
Check config files, mock payloads, and exported records before they move into local environments, CI, or production systems.
Validation before shipping data
Catch malformed JSON early when you are preparing request bodies, fixture files, environment payloads, or automation inputs.
Cleaner collaboration
Turn unreadable JSON blobs into something you can paste into PRs, docs, issues, or team chat without making people squint.
FAQs
Does this tool validate JSON as well as format it?
Yes. It checks whether the input is valid JSON first, then formats it only when parsing succeeds.Can I use this for large API payloads or config files?
Yes. It works well for everyday developer payloads like API responses, config files, event logs, fixtures, and exported JSON records.Is my JSON sent to a server?
No. Formatting and validation happen locally in your browser so the data stays on your machine.What is the difference between beautify and minify here?
Beautify adds indentation and spacing to make the JSON easier to read. Minify removes extra whitespace so the output is more compact.
