Frequently Asked Questions
What is JSON formatting?
JSON (JavaScript Object Notation) formatting, or "pretty printing", adds whitespace, indentation, and newlines to make JSON data human-readable. Compact JSON has no extra whitespace, making it ideal for transmission but hard to read.
Is my JSON data sent to a server?
No. All formatting happens entirely in your browser using JavaScript. Your data never leaves your device — no uploads, no logging, completely private.
What does this tool validate?
The formatter validates that your input is syntactically valid JSON per RFC 8259. It detects common errors like trailing commas, unquoted keys, and mismatched brackets.
