JSON Viewer

• JSON Formatter
• JSON Validator
• JSON Diff
• JSON Tools

Explore JSON as a collapsible tree so you can focus on one branch at a time. Paste or upload your JSON (or drag-and-drop a file); click View as tree to see objects and arrays as expandable nodes. Invalid input shows an error and a snippet, with links to the Formatter and Validator. Clear resets input and tree. All processing is client-side.

• Tree view: Objects and arrays appear as nodes you can collapse or expand by clicking the arrow. Primitives are shown inline.
• Error handling: Invalid JSON shows the parser message and, when available, a snippet around the error. Links to Formatter and Validator help you fix the input.
• Paste, upload, or drop: Paste from clipboard, use the file picker, or drag-and-drop a .json file. Loading new content clears the previous tree and any error.
• Clear: One click clears the input, tree view, and file input so you can load different JSON.

Powered by browser APIs and client-side processing.

Large JSON blobs are hard to scan as raw text. A tree view lets you expand only the parts you care about and collapse the rest, so you can navigate configs, API responses, or exports without getting lost. Running the viewer in the browser keeps your data private and works offline after the page loads.

• Input: Paste JSON or upload / drag-and-drop a .json file. Any valid JSON (object, array, or primitive) is supported.
• View as tree: Parses the input and shows a tree. Click the arrow next to an object or array to collapse or expand it.
• Clear: Clears the text area, tree view, any parse error, and the file input.
