Online JSON Viewer

Paste or upload JSON to validate, format, search, and explore nested objects in an interactive tree view.

How to open a JSON file

  1. Open the File tab and drop or choose a .json file, or paste JSON on the Text tab.
  2. Select View JSON to validate and build the tree.
  3. Expand nodes, search, copy JSONPath, or download the formatted payload. Invalid JSON shows an error and clears the previous tree count.

Explore API responses, configuration files, and other JSON payloads without manually tracing nested braces, arrays, and properties.

How to open a JSON file

Choose the File tab, drop or browse for a .json file (or paste into Text), then select View JSON. Invalid JSON is rejected with an error; valid payloads open in the tree so you can expand nodes, search, and download.

Understand nested data

Expand objects and arrays to see property names, values, data types, and parent-child relationships clearly.

Locate any property

Search across keys and values to find deeply nested information inside large API responses or application payloads.

Copy precise JSONPath

Select a node and copy its JSONPath for automated tests, API debugging, scripts, queries, or technical documentation.

Review development payloads

Inspect REST responses, webhook events, package files, and application configuration in a structured tree view.
