How to use the JSON Viewer & Tree Editor
Explore and edit your JSON visually:
1
Paste your JSON
Paste any valid JSON — objects, arrays, or deeply nested structures — into the input area.
2
Explore the tree
The JSON renders as an interactive tree. Expand or collapse nodes to navigate through nested structures easily.
3
Edit values inline
Click any value to edit it directly. Changes are instantly reflected in the raw JSON.
4
Modify structure
Rename keys, add new fields, or delete nodes directly from the tree view.
5
Copy or download
Copy or download the updated JSON after making your changes.
When to use this tool
The JSON tree viewer is your best tool for understanding and modifying complex JSON structures. Use it when:
- →You receive a large API response and need to understand its structure quickly without scrolling through raw text
- →You're debugging nested JSON and want to expand or collapse sections for clarity
- →You want to edit JSON values or structure without manually rewriting raw text
- →You're working with deeply nested objects and need a visual way to navigate them
- →You're onboarding to a new API and want an interactive way to explore the response shape
Frequently asked questions
Q:What's the difference between the JSON Viewer and JSON Formatter?
The JSON Formatter produces clean, formatted JSON text for copying into code or files. The JSON Viewer presents your data as an interactive tree, making it easier to explore, navigate, and edit nested structures visually.
Q:Can I edit JSON in the tree view?
Yes — click any value to edit it inline. You can also rename keys, add new fields, or delete existing nodes. All changes are reflected in the underlying JSON instantly.
Q:How deep can the tree go?
The viewer supports arbitrarily deeply nested JSON structures. Nodes are expanded by default, and you can collapse any branch to focus on specific parts of your data.
Q:Can I view large JSON files?
The viewer works well for most JSON files. For very large datasets (hundreds of KB+), rendering may take slightly longer depending on your browser. Collapse top-level nodes to keep the interface manageable.
