JSON Viewer

View JSON data in a readable, expandable browser-only workspace with a searchable tree, source panel, and copy-ready paths.

🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.

JSON explorer

Paste valid JSON to inspect it as a structured, readable tree.

Everything stays in your browser; pasted data is never uploaded.
 
 
 
How JSON Viewer works
  1. Paste JSON into the input workspace.
  2. Review the formatted tree and filter keys or values.
  3. Copy the clean JSON when you are ready to reuse it.
