Minified JSON is fine for the wire but hopeless to read. Paste any JSON (one line, garbled, or already partially formatted) and get back a clean, properly indented version with consistent spacing. Pick 2-space indent (common in web/Node), 4-space (Python/Java), or tabs. Optionally sort keys alphabetically for easier diffing.
When to use this
Common reasons to beautify: debugging an API response copied from DevTools, reading a config file that was committed minified, comparing two JSON payloads side-by-side (auto-sort keys first), preparing JSON for a code review.
Frequently Asked Questions
How is this different from JSON.stringify(obj, null, 2)?
It's the same idea but with a UI, auto-repair for broken JSON, optional key sorting, tree view for navigation, and JSONPath lookup. JSON.stringify also fails on invalid input - this tool repairs and beautifies.
Does it preserve key order?
Yes by default - we don't reorder unless you enable 'Sort keys'. Most JSON parsers preserve insertion order in modern environments; the tool respects that.
