My organization has been tasked with parsing raw EDI 271 messages into JSON strings in order to feed a downstream application.  A few key details about the task:

• The raw EDI 271 will be coming across as a standard format from a single outbound upstream system
• The EDI 271 messages adhere to the 5010 standard
• We do not need EVERY field from the EDI message, only a select number of fields.  However some of the fields we need (e.g. coverage details) are dynamic in size and will be variable in # of segments both on the EDI side as well as the receiving JSON side.
