JSON Viewer
View JSON as a collapsible tree — explore nested data visually.
How to use JSON Viewer
- Paste your JSON — an API response, config or export.
- Explore the tree: click to expand objects and arrays, collapse what you don't need.
- Follow the path to your value — the branch trail is the accessor path for your code.
- If nothing renders, the JSON is invalid — the JSON Validator will name the exact error.
What is JSON Viewer?
A JSON viewer renders a document as an interactive tree: objects and arrays become collapsible branches, values sit typed at the leaves, and five-levels-deep nesting becomes something you can actually navigate. It answers the question raw JSON is worst at: what's the structure of this thing?
Even pretty-printed JSON fails past a certain size — a 2,000-line API response is technically readable and practically opaque. The tree flips the reading model: collapse everything, open only the path you're following, and the document's shape reveals itself level by level.
About the JSON Viewer
Paste JSON and explore it as a tree — expand and collapse branches, scan array lengths and object keys at a glance, and drill into exactly the path you care about.
The daily uses: understanding an unfamiliar API's response shape before writing code against it (what's the path to the value — data.items[0].price or data.results.prices?); verifying a payload contains what it should where it should; explaining a data structure to a teammate without making them parse braces; and spelunking config exports or log entries whose depth defeats a text editor.
Invalid JSON can't become a tree — if the paste fails, run it through the JSON Validator to find the syntax error first. Everything renders locally in your browser; private payloads stay private.
