What is JSON formatting?
JSON formatting (or beautifying) adds proper indentation, line breaks, and spacing to make JSON data more readable and easier to debug. Our formatter supports 2, 4, or 8 space indentation.
What does minify do?
Minifying removes all unnecessary whitespace, line breaks, and indentation to create the smallest possible JSON file. This is useful for reducing file size in production environments or when sending data over networks.
How does JSON validation work?
Our validator checks your JSON syntax in real-time as you type. It will instantly show errors with clear messages if your JSON is invalid, including missing brackets, quotes, or commas.
What is tree view?
Tree view displays your JSON data in a hierarchical, collapsible structure that makes it easier to understand complex nested objects and arrays. It color-codes different data types for better readability.
Is my data secure?
Yes! All JSON processing happens entirely in your browser. Your data is never uploaded to any server, stored, or transmitted anywhere. Everything is processed locally on your device.
Can I sort object keys?
Yes! Enable the "Sort keys alphabetically" option in Settings to automatically sort all object keys in alphabetical order when formatting. This is useful for comparing JSON files or maintaining consistent ordering.
