Make Sense of JSON Chaos
API responses come minified. Log files contain single-line JSON blobs. Debugging requires reading JSON that's anything but readable. Sound familiar?
Our formatter takes any valid JSON and makes it human-readable. Proper indentation, syntax highlighting, and collapsible sections. Find what you're looking for instantly.
Invalid JSON? We'll tell you exactly where the error is. Missing comma on line 47? Unterminated string at position 234? You'll know immediately.
