Frequently Asked Questions
What does the viewer do?
It turns your JSON into a collapsible tree so you can explore large or deeply nested data without scrolling through raw text.
Can I collapse parts of it?
Yes. Click a node to expand or collapse it, which makes it easy to focus on one branch at a time.
What if my JSON is invalid?
The viewer reports the parse error so you can fix the JSON before viewing it.
Is my data sent anywhere?
No. The tree is built in your browser, so your JSON never leaves the tab.
Is it free?
Yes. Every tool here is free to use with no sign up.
