Format JSON response from open AI

[shubham_akodiya]

Describe the problem/error/question

I’m using the openAI for image processing but it is not providing me the valid json response. I have already mentioned this in prompt but still not providing the valid json.

What is the error message (if any)?

Hi @shubham_akodiya

Thanks for posting here and welcome to the community!

If your output always has this pattern, you could just transform it with something like:

{{ JSON.parse($json.content.slice(8).slice(0,-10).replace(/\s/g, '').replace(/\n/g, '') + '}') }}

However, I think you could get better (and more stable) results by adding the Structured Output Parser node to do the formatting for you.

Here’s an example for your use case:
