What is JSON Tree Viewer?
Paste JSON and explore it as a collapsible tree with colour-coded types. Search across keys and values and the tree opens to every match, expand or collapse everything with one click, and copy the JSONPath or the value of any node. Large arrays are paged so big API responses stay responsive, and invalid JSON is reported with the line where it breaks. Everything runs in your browser, so your data is never uploaded.

Frequently asked questions
Common questions about JSON Tree Viewer.
A JSON tree viewer shows JSON as nested, collapsible nodes instead of one long block of text, which makes it easier to understand the structure of an API response or configuration file.
No. Parsing and rendering happen in your browser, and nothing you paste is sent to a server.
Hover over any node (or tap it on a touch screen) and use the link icon. The path is copied in JSONPath form, for example $.users[0]["first-name"].
Containers render their first 100 children and load more on request. This keeps very large arrays fast; search still finds matches inside the hidden items.
Common causes are trailing commas, single quotes instead of double quotes, unquoted keys and comments. The error shows the line where parsing failed. Use the JSON Formatter to tidy valid JSON.
