Tentang JSON Visualizer
The JSON Tree Viewer transforms raw JSON text into an interactive, collapsible tree structure that makes complex nested data easy to read and explore. Instead of squinting at minified or deeply nested JSON strings, you get a clear visual hierarchy with color-coded value types, expand/collapse controls for every node, and live search filtering. This tool is invaluable when debugging API responses, inspecting configuration files, or understanding an unfamiliar data schema. Deep nesting, arrays of objects, and mixed data types all render cleanly with indentation guides that show the relationship between parent and child nodes. The search bar filters the tree in real time, highlighting matching keys and values so you can locate specific data instantly without scrolling through hundreds of lines. One standout feature is JSONPath copy: click any leaf value and its full dot-notation path (e.g., `$.user.address.city`) is copied to your clipboard, ready to use in code or queries. A stats panel shows total keys, maximum nesting depth, array count, and object count at a glance. Expand All and Collapse All buttons let you quickly navigate large payloads. Everything runs locally in your browser — no server, no uploads, complete privacy for sensitive data.
Cara Menggunakan JSON Visualizer
- Paste your JSON into the left input panel, or click "Load Sample" to see a demonstration.
- The tree renders automatically on the right as soon as valid JSON is detected.
- Click the arrow (▶) next to any object or array node to expand or collapse it. Click "Expand All" to open every level at once.
- Use the search box above the tree to filter nodes by key name or value. Matching text is highlighted in yellow.
- Click any leaf value in the tree to copy its full JSONPath (e.g., $.address.city) to your clipboard.
- Check the stats bar at the top for a summary: total keys, maximum depth, number of arrays, and number of objects.
Pertanyaan yang Sering Diajukan
What is JSONPath and why would I copy it?
JSONPath is a query language for JSON, similar to XPath for XML. A path like $.orders[0].total uniquely identifies a value within a JSON document. Copying a node's path saves you from manually constructing it and is useful in code, API testing tools like Postman, or jq queries.
How does the search filtering work?
The search matches against both key names and values anywhere in the tree. A node is shown if it, any of its ancestors, or any of its descendants match the search term. Matching text is highlighted so you can spot it at a glance.
Can I explore very large JSON files?
Yes, but performance depends on your browser. For files with thousands of nodes, use Collapse All first and expand only the sections you need. The search feature is particularly helpful for navigating large payloads efficiently.
What do the different value colors mean?
Colors indicate the data type: green for strings, blue for numbers, orange/red for booleans, and gray for null values. This makes it easy to spot type mismatches or unexpected null fields at a glance.
Does this tool validate my JSON?
Yes. If your input is not valid JSON, a parse error message is displayed below the input box with details about where the error occurred, so you can fix it quickly.
Is my JSON data sent anywhere?
No. The entire tree is built and rendered in your browser using JavaScript. Your data is never uploaded to any server.
