JSON Viewer
View JSON as an interactive, collapsible tree to explore nested data easily.
All conversions happen in your browser. No data is sent to our servers - see why that matters. Share links encode your input in the URL itself; nothing is stored on a server. Press Cmd/Ctrl + Enter to convert.
How to View JSON as a Tree
Paste your JSON into the input panel. The viewer renders it as a collapsible tree with values color-coded by type - strings, numbers, booleans, and nulls are instantly distinguishable, and every object or array shows its size at a glance.
Why Use a JSON Tree Viewer?
Deeply nested API responses are painful to read as raw text - matching brackets by eye across hundreds of lines is error-prone. A tree view lets you fold away the parts you don't care about and drill into exactly the branch you're debugging.
Common Use Cases
Developers use the JSON viewer to explore unfamiliar API responses, verify the structure of webhook payloads, inspect configuration exports, and navigate large documents where only one nested section matters.
Frequently Asked Questions
What does the JSON viewer do?
It parses your JSON and displays it as an interactive tree. Objects and arrays become collapsible branches you can expand to explore deeply nested data without scrolling through raw text.
Can I collapse and expand everything at once?
Yes. Use the Expand all and Collapse all buttons above the tree to open every branch or fold the document back to its top level.
Is my JSON uploaded to a server?
No. Parsing and rendering happen entirely in your browser, so API responses containing tokens or personal data are safe to inspect here.
What if my JSON is invalid?
The viewer shows the exact parser error so you can find the problem. Use the JSON Validator for a friendlier summary or the JSON Formatter to clean up the document.
