Beautifier vs. minifier

A JSON beautifier expands JSON with indentation and line breaks so a human can read it, while a minifier does the opposite to save space. Beautifying is what you want when reading API responses, reviewing data, or preparing examples for docs.

Frequently Asked Questions

Is a beautifier the same as a formatter?

Effectively yes — both pretty-print JSON. Use whichever name you prefer; the result is clean, indented JSON.

Which indent should I pick?

2 spaces is the most common for JSON. Use 4 spaces or tabs to match your project's style.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
