JSON Tree Viewer guide

Use this free JSON Tree Viewer to inspect JSON objects and arrays as an indented tree locally in your browser.

JSON Tree Viewer helps you inspect JSON objects and arrays as an indented tree for developers, analysts, API testers, config editors, and AI-generated JSON reviewers. It opens the matching Tiny Work Tools utility directly and runs in your browser after the page loads.

Best for

  • checking nested keys, array lengths, and primitive values without uploading JSON to a server
  • Fast browser-based utility work without creating an account.
  • Simple checks before moving data, files, or numbers into another workflow.

Not for

  • visual diffing, schema validation, API testing, large document editing, or sensitive production secrets
  • Regulated, certified, or production-critical decisions that require a specialist tool.

How it works

  1. Open the tool page and use the preselected utility.
  2. Enter the text, numbers, or file requested by the tool.
  3. Review the result and download or copy it when the output looks right.

  • Use JSON Tree Viewer for developers, analysts, API testers, config editors, and AI-generated JSON reviewers.
