Short answer

How can I turn text into JSON using my AI?

Your AI uses the OpenAI connector to parse unstructured text and map it to a schema you define. You'll get clean, machine-readable objects ready for your database or application. Here is how the process works.

Data outcomes

Where your data lands.

What happens to your text once the AI processes it.

VALID

Clean JSON objects

The AI converts raw text into valid JSON. You get data that fits your application's schema perfectly.

SCHEMA

Mapped fields

The AI identifies specific entities like names, dates, or amounts. It places them into the exact keys you requested.

RAW

Unstructured text

The original messy documents remain untouched. The AI only produces the extracted data, leaving your source files as they are.

HUMAN

Manual review

You decide if the extracted data is accurate. The AI provides the structure, but you handle the final validation.

The workflow

What your AI does when text arrives.

The AI handles the heavy lifting of parsing and formatting.

  1. Read the text

    Your AI client ingests the raw, messy document you provide.

  2. Identify entities

    The AI scans the text to find the specific pieces of information you need.

  3. Apply schema

    The AI forces the extracted information into a strict JSON format.

  4. Validate format

    The AI ensures the final object adheres to your required structure.

FAQ

How this task behaves

  • 01

    Can the AI change my original documents?

    No. The AI only reads the text to create new JSON objects. It cannot edit or overwrite your source files.

  • 02

    Does the AI decide the JSON keys?

    You should define the keys in your prompt. While the AI can suggest them, you get the best results by telling it exactly what schema to follow.

  • 03

    Can I use this to update my database directly?

    No. This connector produces JSON text. You must take that JSON and send it to your database using your own application or another tool.

  • 04

    What happens if the text is too messy?

    The AI will attempt to find the data, but if the information isn't in the text, it won't invent it. You'll get null values or empty fields instead.

  • 05

    Do I need to write code to get JSON?

    No. You just need to tell your AI client that you want the output in JSON format.
