User Guide
JsonFlow — JSON canvas and tree view
Format JSON, inspect it as collapsible nodes, and edit values without losing your place.
Scenarios
Designed for backend developers, API debuggers, frontend developers, and data analysts to organize and inspect nested or complex JSON data payloads in a visual interface.
How to Use
- Paste your JSON text into the input panel.
- The view automatically parses it into collapsible nested nodes with color-coded syntax highlighting.
- Enter keys or values in the search bar to highlight targets and auto-expand relevant paths.
- Double-click to edit, add, or delete nodes directly on the tree, or switch to Raw mode.
- Click Copy or Download to save the clean, formatted JSON data.
Privacy Policy
Your JSON payloads stay in page memory and are never sent to a cloud database, keeping api keys and corporate secrets perfectly secure.
Frequently Asked Questions
Q: What happens if my JSON has syntax errors?
A: JsonFlow includes real-time syntax checking. It will highlight formatting errors and indicate line numbers to help you fix them quickly.
Q: How large of a JSON file can it handle?
A: It easily processes files up to several megabytes. For extremely large files (e.g., 50MB+ server logs), browser memory limits might slow down the tree visualization.
Q: Can I expand or collapse all tree nodes at once?
A: Yes. The toolbar provides 'Expand All' and 'Collapse All' shortcuts, allowing you to view the top-level structure or dive deep in one click.
