Converting Json To FHIR

Folks. New to the community. Working on a small project and need guidance.

I need to convert Json output from a Database to FHIR format. My first try was to use Azure FHIR liquid templates but the templates available for JSON to FHIR conversion are quite limited - that means a significant uplift. Are experts here familiar with any converter tool or app that does this. Any guidance or help will be apprecieted.

Any converter will have to understand the structure of your database output.
Does the output follow some standard that others might use?
Is it a close representation of the database’s table structure?
If no one else has the same structure, you’ll have to design your own conversion.
