HFQL Client

About the tool

HFQL (HAPI FHIR Query Language) is a query language for FHIR developed to support healthcare data analytics. HFQL queries can be executed against FHIR servers using the $hfql-execute operation which returns the results in the form of a CSV file.

This tool allows you to execute HFQL queries against FHIR servers online, without worrying about the details of the underlying HTTP protocol.
