JSON Viewer

Explore JSON as a collapsible tree with types, counts and copyable paths.

About the JSON Viewer

Large JSON documents are easier to understand as a tree. The JSON Viewer shows every object and array as a collapsible node with its type and size, and lets you copy the path to any value.

Everything runs in your browser, so your input is never uploaded to a server.

How to use the JSON Viewer

  1. Paste JSON or open a file.
  2. Expand and collapse nodes to explore the structure.
  3. Copy a value or its path (for example data.items[0].id) for use in code.

Frequently asked questions

How large a file can it open?

Files of several megabytes work well, since nothing is uploaded and nodes are only rendered when expanded.

What path format is copied?

JavaScript-style access paths, such as user.addresses[1].city, ready to paste into code or a query.
