Interactive JSON Viewer & Explorer
Inspect complex JSON structures with collapsible tree nodes, type chips, JSONPath extraction, and search filtering — 100% in your browser.
How It Works
Fast, secure, browser-native JSON processing in 3 simple steps
Paste or Upload JSON
Paste your raw data directly into the editor or upload any .json, .jsonc, or .json5 file.
Inspect & Validate
Instantly view syntax errors, health score, duplicate keys, and potential sensitive credentials.
Format, Diff or Export
One-click format, run structural comparisons, generate redacted copies, or download the clean output.
Why Use an Interactive JSON Viewer?
Reading large, deeply nested JSON responses in plain text can be slow and error-prone. JSONForge's JSON Viewer transforms raw JSON text into an interactive, color-coded visual hierarchy where you can expand and collapse containers, inspect array lengths, view data types, and copy JSONPath expressions with a single click.
Collapsible Branches
Expand or collapse any object or array branch to focus only on relevant fields, or use "Expand All" / "Collapse All" for instant overview.
One-Click JSONPath Copy
Hover over any key or nested node to instantly copy its exact JSONPath (e.g. $.nodes[0].services[1]) directly into your clipboard.
