JSON Tree Viewer
Visualize JSON as a collapsible tree. Expand nested objects and arrays to navigate complex structures quickly.
Why use a JSON tree viewer?
Deeply nested JSON is hard to read as plain text, even when it is properly indented. A tree view lets you collapse sections you don't care about and drill into the parts that matter. JSON Mint color-codes strings, numbers, booleans, and null so data types are visible at a glance, and shows the count of items in arrays and objects next to each collapsed node.
Paste any JSON — an API response, a config file, a GraphQL payload — and the tool renders the structure instantly. Everything runs in your browser, so the data never leaves your machine.
Frequently Asked Questions
How is the tree viewer different from the formatter?+
The formatter pretty-prints JSON as text. The tree viewer renders it as a collapsible UI so you can fold parts you don't need and focus on the structure you care about.
Can I copy individual values?+
You can select text directly from the tree in your browser. Future versions will add one-click copy of any node's JSON path.
Does it handle large JSON files?+
Yes, but rendering thousands of nodes at once can be slow. Collapse top-level nodes to keep the view responsive.
