How to use the JSON Viewer
- Paste your JSON into the input box above
- Click View JSON
- The tree view below shows every object and array as a collapsible node
- Click any node to expand or collapse it
The tree view is especially useful for deeply nested API responses where scrolling through raw text is slow. You can collapse branches you don't need and focus on the parts of the structure that matter.
JSON Viewer vs JSON Formatter
A JSON formatter adds indentation and line breaks so raw JSON becomes readable text. A JSON viewer goes further — it renders the JSON as an interactive tree where you can expand and collapse individual nodes. Both tools are useful at different points of the same workflow:
Frequently Asked Questions
What is a JSON viewer?
A JSON viewer displays JSON data as an interactive tree where you can expand and collapse nested objects and arrays. This makes it much easier to navigate large or deeply nested JSON documents compared to reading raw text.
What is the difference between a JSON viewer and a JSON formatter?
A JSON formatter adds indentation and line breaks to make raw JSON readable as text. A JSON viewer renders JSON as an interactive tree with collapsible nodes — you can navigate the structure without scrolling through all the text at once.
Can this viewer handle large JSON files?
Yes. The viewer runs entirely in your browser and can handle JSON documents of several megabytes. For very large files (10 MB+), tree rendering may be slower depending on your browser and device.
Is my JSON sent to a server?
No. All JSON processing happens entirely in your browser using JavaScript. Your data never leaves your device.
