How to use this tool

Master the visual editor in 3 simple steps

Adding Basic Fields

Click the 'Root Node' button to add fields. Use the dropdown to switch between String, Number, and Boolean. The value input will adapt based on the selected type.

Creating Nested Structures

Change a node's type to 'Object' or 'Array'. Hover over the node to reveal the blue '+' button. Clicking it will append a sub-field recursively to that specific node.

Real-time Search & Export
