JSON Tree Viewer
When you need to inspect source code or structured data and report an inspection report, JSON Tree Viewer gives you a browser-based workflow with a visible input, primary action, and an inspection report.
How to Use JSON Tree Viewer
- Prepare source code or structured data and enter or select source code or structured data in the workspace.
- Review the available options, then choose Build Tree to run the task.
- Inspect an inspection report, compare it with the source and selected settings, and save or copy it only after it meets your requirements.
What Is the JSON Tree Viewer?
The JSON Tree Viewer is a free online utility that helps you explore JSON data in a hierarchical tree structure. It provides a focused workspace for developers, QA teams, designers, students, and technical writers.
Use this inspector while debugging, validating assumptions, or comparing input against expected application behavior. The current interface gives you Input, Result so the task can be completed without navigating away from the page.

When to Use This Tool
- Quick one-off tasks using the JSON Tree Viewer without setting up a separate desktop utility.
- Checking or preparing data while debugging, documenting, publishing, or testing a workflow.
- Creating a clean result that can be copied, downloaded, or transferred into another application.
Tips for better results
- Test both a known-good example and an intentionally invalid example.
- Do not rely on one browser-side check as a substitute for server-side validation.
- Save representative test cases when the same format or pattern is used repeatedly.
JSON Tree Viewer Example
Paste a minimal valid sample into source code or structured data, run JSON Tree Viewer, and test the an inspection report in the target application before using it with a larger production payload.
