Converting a CSV file into a nested JSON file using ./jq

I am hoping I can get an answer on this question. I am using ./jq to convert a CSV file into a file of JSON objects. Each line of the CSV input represents a JSON object. A sample of the CSV input is as follows:

loyalty_card_num,extended_data_source,is_pharmacy_linked,first_linked_date,linked_store,is_caregiver,caregiver_first_linked_date,caregiver_store6105700000000170419,PharmacyLinks,false,,,false,,6105700000006125318,PharmacyLinks,True,2022-12-27,7236,false,,

The resulting JSON file I am trying to create is:

{"loyaltyID":"6105700000000170419","extendedDataSource":"PharmacyLinks","extendedData":{"firstLinkDate":"","isCaregiver":"false","caregiverStores":"","caregiverFirstLinkDate":"","isPharmacyLinked":"false","linkedStores":""}}{"loyaltyID":"6105700000006125318","extendedDataSource":"PharmacyLinks","extendedData":{"firstLinkDate":"2022-12-27T00:00:00-0500","isCaregiver":"false","caregiverStores":"","caregiverFirstLinkDate":"","isPharmacyLinked":"True","linkedStores":"7236"}}

My ./jq code is:

jq --slurp --raw-input --raw-output \'split("\n") | .[1:] | map(split(",")) |    map(        {"loyaltyID": .[0],"extendedDataSource": .[1],"extendedData":            {"firstLinkDate": .[3],"isCaregiver": .[5],"caregiverStores": .[7],"caregiverFirstLinkDate": .[6],"isPharmacyLinked": .[2],"linkedStores": .[4]            }        }    )' \  short.csv > short.json

The result of the above code creates an array of nested JSON object:

[  {"loyaltyID": "6105700000000170419","extendedDataSource": "PharmacyLinks","extendedData": {"firstLinkDate": "","isCaregiver": "false","caregiverStores": "","caregiverFirstLinkDate": "","isPharmacyLinked": "false","linkedStores": ""    }  },  {"loyaltyID": "6105700000006125318","extendedDataSource": "PharmacyLinks","extendedData": {"firstLinkDate": "2022-12-27","isCaregiver": "false","caregiverStores": "","caregiverFirstLinkDate": "","isPharmacyLinked": "True","linkedStores": "7236"    }  }]

I don't want an array but a separate JSON object for each elements in the array. Using the -c switch will just put the entire output on one line. So my goal is to get rid of the [] and have one object per line. Thank you in advance.
