Helm to create configMap for json file

I have a need to create configmap in Helm from multiple files (json,.js etc).I am not getting any proper lead. Can somebody please help how to start. Thankyou

I have created a directory outside the template in Helm Chart and saved all my files(3json and 1 .js file)inside the directory called Files and then inside the template folder I have deployment and conifigmap.yaml file. My config.yaml files looks like below:

apiVersion: v1kind: ConfigMapmetadata:      name: m-configmap-{{ .Release.Name }}      namespace: {{ .Release.Namespace }}      labels:            chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"            release: {{ .Release.Name }}            heritage: {{ .Release.Service }}data:   config.json: |-    {{ .Files.Get "bp.json" | indent 4 }}    {{ .Files.Get "cona.json" | indent 4 }}    {{ .Files.Get "conb.js" | indent 4 }}    {{ .Files.Get "service.json" | indent 4 }}

while trying to check through the command: It simply does not return any value. What am I doing wrong?

helm template master --debug outputs:
