How to use this tool

Define properties with a name, description, and type. Each property becomes a property in the generated JSON schema.
For text (string) fields, choose "is any length" or "between" to set character limits. For number (integer) fields, choose "is any range" or "between" to set numeric bounds. For text (picklist) and list (array) fields, add options using the input and + button.
