Data Types and Validation

The data editor supports a small set of types and enforces validation rules to keep templates stable.

Supported Types

• String
• Number
• Boolean
• Array
• Object

Key Rules

• Keys are required for object fields.
• Keys must be valid identifiers: letters or underscores first, then letters, numbers, or underscores.

Arrays and Objects

• Arrays use a schema to define item types.
• Object fields can nest other objects or arrays.

Depth Limit

Nested structures are limited to 5 levels. When the limit is reached, array and object types are disabled to prevent deep recursion.

Raw JSON Validation

In Raw mode, the editor checks that:

• JSON syntax is valid.
• The root is an object.
• Field keys and depth limits are valid.
