Hi,
Couple of questions before start.
What are rules for changing name? EX. for 160700, will you enter the First name and Last name some where to copy from?
Approx how many rows are in real files?
IF they are not in large number, then Excel VBA will be [login to view URL] some other tool may be required to use.
Please also send the JSON and HL7 files fr review too.
Thanks
