View JSON in your browser.
Drop a JSON file and explore it as a collapsible tree instead of a wall of brackets.
Key points
- Drop a JSON file and explore it as a collapsible tree instead of a wall of brackets.
- Branches render only when you expand them, so large structures stay responsive.
- Invalid JSON falls back to the raw text with the parse error shown, never an error page.
- A copy button puts the raw JSON on your clipboard; files up to 10MB open in the browser.
Raw 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, open its link, and the structure becomes browsable.
If the JSON is messy (minified, or inconsistently indented), clean up minified JSON 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, you can load a CSV as a table instead.
When you need to share the file, host a 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 that NudgeHost's free developer tools sit naturally alongside this viewer.
The viewer is free with no limits. Account-level features like custom domains live on the Pro tier.

Will it tell me if my JSON is invalid?
Yes. If the file can't be parsed, the viewer shows the parse error and falls back to the raw text, so you still see the content.
Can it handle large JSON files?
Files up to 10MB open as a tree, and branches render as you expand them so deep structures stay responsive. Bigger files are offered as a download.
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.
