JSON Formatter / Minifier
About JSON Formatter
Format and minify JSON to improve readability, debugging and sharing. Paste JSON on the left and use Format or Minify. If your data is URL-encoded, decode it with the URL Encoder/Decoder. For Base64 payloads, first decode via the Base64 Encoder/Decoder.
Ideal for API payloads, configuration files and logs. One‑click copy makes reuse effortless. When dealing with encoded identifiers or hashes, 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 Encoder/Decoder 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.
