JSON Formatter / Minifier
Format and validate JSON data
About JSON Formatter
Format and minify JSON to improve readability, debugging and sharing. Paste JSON on the left and use Format or Minify. If data is URL‑encoded, use URL encoding/decoding. For Base64 payloads, first decode via Base64 encoding/decoding.
Ideal for API payloads, configuration files and logs. One‑click copy makes reuse effortless. For hashes or identifiers, cross‑check with MD5/SHA tools, and for date tokens use the Timestamp Converter.
Common Use Cases
- Inspect and share API responses
- Clean up app configuration files
- Beautify JSON logs for troubleshooting
- Prepare JSON examples for documentation
How It Works
- Applies consistent indentation and line breaks
- Normalizes whitespace without changing values
- Warns when JSON is invalid
- One‑click copy of the result
FAQ
Does it support large JSON?
Yes for typical files. Very large payloads may be slower; consider splitting or server processing. If content is encoded, decode first via URL encoding/decoding or Base64.
Will keys order change?
No. Formatting only affects whitespace and indentation.
Is my data uploaded?
No. All processing happens locally in your browser.
How to share the result?
Use Copy, or save as `.json` and share.
