JSON Pretty Print
JSON Pretty Print turns compact or messy JSON into clean, indented, color-highlighted structure that is easy to read. Choose 2 spaces, 4 spaces or tab indentation to match your project's style.
It is ideal for inspecting API responses and configuration files. Everything runs in your browser, so your JSON stays on your device.
How to use JSON Pretty Print
- 1
Paste your JSON
Drop minified or unformatted JSON into the input box.
- 2
Pick an indent
Choose 2 spaces, 4 spaces or tabs — the output updates live.
- 3
Copy the result
Grab the beautified JSON with the copy button.
Choosing an indentation style
Two spaces is the most common convention for JSON and keeps deeply nested structures from drifting too far to the right. Four spaces gives more visual separation, and tabs let each reader pick their own width in an editor.
Whichever you choose, indentation is purely cosmetic: the parsed data is identical, so you can reformat freely without changing meaning.
Pretty printing vs minifying
Pretty printing adds whitespace to make JSON human-friendly during development and debugging. Minifying does the opposite, stripping whitespace to shrink the payload for transport. They are two views of the same data.
A common workflow is to pretty print a response while debugging, then minify the final version before shipping it.
Frequently asked questions
- What indentation options are available?
- You can beautify with 2 spaces, 4 spaces or a tab character.
- Does pretty printing validate my JSON?
- Yes. The input is parsed first, so invalid JSON shows an error instead of formatted output.
- Is my JSON uploaded?
- No. Formatting runs entirely in your browser.
