Hi team

I am new to your site and new to JSON so please be gentle.  
I am utilising Power Automate to look at categories assigned to my emails and then push some data back to an SQL database.

I used graph explorer to help me get the right API message and have added a JSON parse into my workflow.

With that context out of the way - one of the fields from the email is Subject which caontains a refernce number. My question is - how do I extract the reference number as a seperate value from the subject in order to use that as a coilumn to push to SQL. Essentially how do I use mid and string type syntax in JSON. I hope this resembles some sense and appricaite any feedback. Happy to upload somethign if needed.

cheers

Hi @cgrigg ,

I think you have confused what this forum is about. It is **not** about the general usage of JSON but using the Javascript/Typescript framework [JSON Forms](https://jsonforms.io/) to render forms based on a JSON schema.

Good luck with your issue and feel free to come back with questions relating to JSON Forms anytime 🙂

Best regards,  
Lucas
