Hi,

This library works very well. Thanks for this.
But what If my key has multiple values then how to specify that in the excel file?

[y5158]

I am talking about the following example

{
	"empid": 1
            "Personal info": [
                     {
                         "emailid": "abc@xyz.com",
                          "Phone number":"9999999999"
                     }
              ],
              "address" : "India"
    }
