Frequently Asked Questions

What is JSON formatting?

JSON formatting (also called pretty-printing) adds indentation and newlines to make JSON data readable. Minified JSON is compact but hard to read; formatted JSON is structured with each key/value on its own line.

What indentation should I use?

2 spaces is the most common convention (used by Node.js and most formatters). 4 spaces is also popular. Tabs work well in editors that support variable tab widths.

Is my data safe?

Yes — all formatting happens entirely in your browser. Your JSON data never leaves your device and is never sent to any server.

What is the difference between format and minify?

Formatting adds whitespace for readability. Minifying removes all unnecessary whitespace to reduce file size, ideal for production APIs and data transfer.
