Package org.springframework.ai.converter

@NonNullApi @NonNullFields package org.springframework.ai.converter

Provides converters for transforming AI model text outputs into structured Java types.

The output of AI models traditionally arrives as a String, even if you ask for the reply to be in JSON. This package provides specialized converters that employ meticulously crafted prompts and parsing logic to convert text responses into usable data structures for application integration.

For detailed documentation and usage examples, see the Structured Output Converter Reference Guide.
