JSON Viewer
Paste raw JSON and this tool renders it as an interactive, collapsible tree instead of a wall of brackets and commas. It's a lot easier to dig through a large API response or config file this way without losing your place, and syntax errors get flagged so a missing comma or bracket doesn't slip past you.
Paste compact JSON like this:
{"user":{"name":"Ana","active":true}}
→
A collapsible tree: user → name: "Ana", active: true
Can I collapse and expand nested objects?
Yes, every object and array in the tree can be collapsed or expanded on its own, which makes navigating deeply nested API responses a lot easier.
Does it tell me if my JSON is invalid?
Yes. If the JSON can't be parsed, the tool tells you that instead of quietly showing a broken or empty tree.
Is this the same as the XML/JSON converter?
No. The converter transforms JSON into XML, or the other way around. This viewer just displays JSON for reading; it doesn't change or export anything.
Is my JSON data sent anywhere?
No, parsing and rendering happen locally in your browser, so pasted data isn't uploaded to a server.
