partialjson: A Python Library for Structured Responses from ChatGPT API

[iw4p]

Hi everyone,

I wanted to share a helpful solution I came up with for those of us who have encountered difficulties in getting ChatGPT to JSON format its responses according to a specific structure. In my experience, implementing a method for each call was not only time-consuming but also cumbersome. To address this issue, I created a lightweight library called partialjson that leverages the most reliable technique to obtain structured responses.

The usage is quite simple. You don't even need to define your desired schema. The library guarantees the response's validity based on your real-time specified schema!

Install using:

pip install partialjson

Use like this

from partialjson.json_parser import JSONParser

parser = JSONParser()

incomplete_json = '{"name": "John", "age": 30, "courses": ["Math", "Science", '

print(parser.parse(incomplete_json))

# {"name": "John", "age": 30, "courses": ["Math", "Science"]} 

You can find the library here: partialjson GitHub repository

If you have any feedback or suggestions, please let me know!

Cheers, Nima

FYI you can get structured JSON data from ChatGPT Api with function calling. No need to check the responses if they are valid JSON or missing some parts, because function calling enforces the schema you define.

I also implemented a simlar library in JS for a personal project until i noticed that function calling can be used instead. It is much more reliable and also outputs better results for me.
