Helm variables used at custom places - kubernetes

Question

I am not able to reference variable inside a nested variable in Helm. Also, I am not able to do this as nested reference. I want to retrieve all client variables under client name using the value of the client_name variable. How can I do that?
Values.yaml
clients:
client1:
incomigBucket: databucket
outgoingBucket: tempbucket
webURL: http://example.com
client2:
incomingBucket: databucket
outgoingBucket: tempbucket
webURL: http://example.com
I want to store client variables values in one variable and want to use it at different places in my Json file. if I use range function then it create section twice(as I have mentioned 2 clients), is there any thing in Helm I can use which can store these variables dynamically and use it in custom places in json file?
Sample File Section:
"FileConfig": {
"Client1": {
"incomingLocationPath": "s3://{{ .Values.clients.client1.incomingBucket }}/dir1/dir2",
"outgoingLocationPath": "s3://{{ .Values.clients.client1.outgoingBucket }}/dir1/dir2",
},
"Client2": {
"incomingLocationPath": "s3://{{ .Values.clients.client2.incomingBucket }}/dir1/dir2",
"outgoingLocationPath": "s3://{{ .Values.clients.client2.outgoingBucket }}/dir1/dir2",
}
}

I am not entirely sure where you intend to use this snippet. I assume it is inside a configMap. At least, I am not aware of any resource that had FileConfig section. I wouldn't know why it should be JSON either.
The basic pattern could look like this.
fileConfig:
{{- range $client, $config := .Values.clients }}
{{ $client }}:
incomingLocationPath: "s3://{{ $config.incomingBucket }}/dir1/dir2"
outgoingLocationPath: "s3://{{ $config.outgoingBucket }}/dir1/dir2"
{{- end }}
In something like a configMap to create JSON it could look like this.
kind: ConfigMap
apiVersion: v1
metadata:
name: file-config-json
data:
config.json: |
"fileConfig": {
{{- range $client, $config := .Values.clients }}
"{{ $client }}": {
"incomingLocationPath": "s3://{{ $config.incomingBucket }}/dir1/dir2",
"outgoingLocationPath": "s3://{{ $config.outgoingBucket }}/dir1/dir2"
}
{{- end }}
}
