import Date fields

[CodeMasterZeroOne]

Hello, and thank you for this app, helped me a lot! I am new to firestore and I was able to import my data from xlsx but date fields '2020-01-01' are written to firestore as strings how can I change that to write those as timestamp?
Thanks in advance

create JSON file with appropriate type, file format as below

{
	"collection:cust": [
		{
			"age": "1/1/2022",
                        "createdAt": "{\"type\":\"timestamp\",\"data\":1641141025}",
			"mobile2": "",
			"name": "test1",
			"locality": "Mumbai",
			"updatedAt": "{\"type\":\"timestamp\",\"data\":1641141025}",
			"mobile": "98989898"
		},
		{
			"locality": "bbbb",
			"updatedAt": "{\"type\":\"timestamp\",\"data\":1641141025}",
			"mobile": "1234567",
			"name": "bbb",
			"mobile2": "",
