Excel list substitution for loop of list of items

Hi,

Below is my Post parameter, where it lists ICD-10 codes with the name description.

{"workingDiagnosis":"G43.D","description":" Abdominal migraine"}

I could create a csv list of ICD-10 codes and make this variable dynamic, but I do not want to do that because sometimes ICD-10 codes change.

With that said, when I search in my page, it gives me a list of options for all ICD-10 codes available.

How can I make this loop from the list of ICD-10 codes from the first code to the last code listed in my page?

Please see image attached on how the list of codes are displayed in the page.

Thank you
