I am extracting data from a excel sheet and storing in a `dictionary` variable, for example:

```
data = {"customer_name":"XYZ", "customer_mobile":"989898", "customer_country":"country"}

```

Now I need to call a rest api to create a customer, need to send data in json as :

```
{
  "custName": "string",
  "custMobile": "string",
  "custCountry":"string",
}

```

The keys in `dictionary` and `json` are different and cant change either of them, so how can I map these two?

Thanks
