Key points
- Drop a JSON file and explore it as a collapsible tree instead of a wall of brackets.
- Lazy-loads large structures so multi-megabyte files stay responsive.
- Invalid JSON is caught immediately with a pointer to where the syntax breaks.
- Pairs naturally with the JSON formatter for tidying messy input first.

Try it freeRaw JSON is readable in theory and painful in practice. A large API response or config file is hundreds of lines of nested braces. A tree viewer lets you collapse what you don't care about and drill into what you do. Drop a file here and it becomes browsable immediately.
If the JSON is messy (minified, or inconsistently indented), run it through the JSON formatter first; it tidies the structure so the tree view is even easier to scan. For tabular data that arrived as JSON but would read better as rows and columns, the the CSV viewer is the companion tool.
When you need to share the file, host a file any JSON file and send a link. That's how you hand a teammate an API response without pasting 500 lines into Slack. Developers will also find the rest of NudgeHost's free developer tools sit naturally alongside this viewer.
The viewer is free with no limits. Account-level features are on upgrade to Pro.
Frequently asked questions
Will it tell me if my JSON is invalid?
Yes. If the file can't be parsed, the viewer points you to where the syntax breaks.
Can it handle large JSON files?
Yes, up to the 25MB free-plan limit. The tree loads lazily so big files stay responsive.
Is this the same as a JSON formatter?
Related but different. The viewer explores structure; the formatter rewrites the file with clean indentation. Use them together.
