JSON Viewer Online with Tree and Grid Views
Explore JSON as an interactive tree instead of reading a wall of text. Expand only the branches you need, search nested keys, inspect paths and switch to a table when the document contains record-like arrays.
How to use this JSON tool
- Paste JSON, drop a file onto the editor or load the sample.
- Choose Tree to explore objects and arrays branch by branch.
- Search for keys or values and select a node to see its path.
- Switch to Grid for tabular records or Code for the complete formatted document.
Understand nested JSON faster
Tree view represents objects, arrays and primitive values with collapsible rows. This is useful when an API response contains several levels of metadata, pagination, user records and embedded collections. Expand All provides a complete overview, while Collapse All returns to the main structure when the document becomes crowded.
Searching helps locate a property without scanning every line. Selecting a node exposes its JSONPath-style location, and pinning keeps important values available while you inspect another part of the tree.
Choose the right view for the data
Tree view is best for hierarchy, Code view is best for copying a complete formatted document, and Grid view is useful for arrays of similarly shaped records. JSONFlow also displays document statistics such as node count, depth and array size so you can understand the payload before working through it.
Large documents are processed locally. To protect the browser from expensive rendering, JSONFlow automatically favors the formatted view at higher file sizes and warns before opening heavier visualizations.
Frequently asked questions
Can I search inside the JSON tree?
Yes. Use the tree search field to locate matching keys or values and move through the document more quickly.
When should I use Grid view?
Grid view is most useful for arrays containing records with similar fields, where rows and columns are easier to inspect than nested text.
Can the viewer handle large JSON files?
Yes, with safeguards. JSONFlow monitors file size and can limit expensive tree or grid rendering for very large documents to keep the browser responsive.
