JSON Tree Viewer
Read deeply nested JSON as an expandable tree.
Opens the editor in tree view with the sample loaded. Expand and collapse branches — everything stays in your browser.
Large, deeply nested JSON is painful to read as raw text. A tree viewer turns the document into an interactive outline: every object and array becomes a branch you can expand or collapse, so you can drill straight down to the one field you care about and hide the rest.
Why tree view beats plain text
- Structure at a glance. Nesting, arrays and object boundaries are obvious instead of buried in brackets and indentation.
- Collapse the noise. Fold branches you do not need so a 5,000-line response fits on one screen.
- Find the path. See exactly where a value lives — which object, which array index — which is what you need when writing a query or accessor.
Tree and table, side by side
Some data is a shape; some data is a list. The editor supports both. Use tree view for nested configuration and mixed objects, and switch the same document to table view to scan an array of records like a spreadsheet — one row per item, one column per field. Switching view never changes the underlying data.
Built for big documents
The viewer renders large files without freezing the tab, and you can jump back to text view to edit, format or copy at any time. Need a bird's-eye picture of how everything connects? The JSON visualizer draws the whole document as a node graph.
Local and private
The tree viewer runs in your browser. Your JSON is never uploaded, so you can inspect internal API responses and sensitive exports without sending them anywhere.
Frequently asked questions
How do I view JSON as a tree?
Paste your JSON into the editor and it renders as a collapsible tree. Click any branch to expand or collapse the objects and arrays inside it.
Can it handle large JSON files?
Yes. The tree renders large documents efficiently, and you can collapse branches you do not need to keep everything readable.
What is the difference between tree view and table view?
Tree view is best for nested objects and mixed structures. Table view is best for arrays of similar records, which it shows as rows and columns like a spreadsheet.
