About the JSON Formatter & Beautifier
Paste JSON to format it with consistent indentation so it’s easy to read, or sort keys alphabetically to compare objects. If the JSON is invalid, you’ll see what’s wrong and the line and column where it happened.
Everything runs in your browser — API responses, config files and tokens you paste never leave your device.
How does the JSON Formatter & Beautifier work?
The formatter parses your JSON with the same strict parser browsers use, then prints it back with consistent indentation — 2 spaces, 4 spaces or tabs. Because it really parses the data, anything that isn’t valid JSON is reported with the line and column where parsing failed instead of being silently “fixed”.
Example
Input: {"name":"Ana","skills":["SQL","Python"],"active":true}
Formatted with 2 spaces, each key goes on its own line and the array is indented inside the object — the same data, just readable. Sorting keys puts active before name and skills, which makes two objects easy to compare.
