API payload cleanup
Format responses before you paste them into tickets or docs.
Documentation
JSON Formatter documentation
Validate, pretty-print, and minify JSON payloads with copy-ready output and payload stats.
Overview
Use it when the format needs to change, not the meaning
Use the formatter when JSON needs to be checked, cleaned up, or compressed into a single line.
Compact output
Minify JSON when space matters more than readability.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts JSON objects and arrays.
- Whitespace can be cleaned up without changing the structure.
- Payloads should stay within the tool’s normal size limits.
Walk through it
Follow the same sequence you see in the tool
Workflow
Format JSON
Use this path when you want the payload to be easier to read.
- Paste the JSON into the editor.
- Choose pretty-print or minify mode.
- Run the formatter and copy the result after validation passes.
What you get
Check the result before you copy it into the next step
Pretty JSON
Readable output keeps indentation and structure clear.
Minified JSON
Compact output removes extra whitespace for embeds or transport.
Validation state
A pass or fail state tells you whether it is safe to copy.
Avoid these mistakes
Small input problems create the biggest conversion errors
Trailing commas
Fix invalid syntax before expecting the formatter to succeed.
Non-JSON text pasted in
The tool only formats actual JSON values.
