JSON Formatting and Validation
JSON is a popular format for APIs and configuration because it’s lightweight and easy to parse. The downside is that large JSON payloads can get hard to read fast—especially when everything is on one line.
A formatter makes JSON easier to work with by applying consistent indentation and line breaks. Your data doesn’t change—only the whitespace—so it’s safer to review, debug, and share.
How do I pretty print JSON?+
Paste your JSON and click format. Errors are highlighted with their location.
Is my JSON sent to a server?+
No. It is parsed and formatted entirely in your browser, so API responses and secrets stay private.
Is it free?+
Yes. No signup, no limits, no watermarks.
