FAQ
- How does the JSON-to-prompt conversion work?
- The tool parses the JSON input, walks all keys in the top-level object, infers each field's type (string, number, boolean, array, object, null), and generates a prompt listing each field with its type and a description derived from the key name. It also adds instructions telling the model to use only these fields and no extras.
- What if my JSON has nested objects?
- Nested objects are shown as type "object" with a note indicating the key contains a sub-object. For deeply nested structures, the generated prompt describes the top-level keys and notes the presence of child objects. You can manually expand the descriptions after copying.
- Can I use this with OpenAI function calling instead of a prompt?
- For function calling you need a formal JSON Schema, not a natural language prompt. Use the AI JSON Schema Builder tool instead, which generates a proper JSON Schema with type annotations and required fields. This tool generates a human-readable prompt suitable for system or user messages.
Paste a JSON object or array and automatically generate an LLM prompt that instructs the model to respond in exactly that structure. The tool analyzes each key, infers the type, and produces a clear prompt listing all fields with types and inferred descriptions. Includes instructions for exact types, required fields, and no extra fields. Useful when you have an example output and want to generate a prompt that reliably produces that shape.
