HI @Nisha_K21

Use a simple JsonConvert.SerializeObject(jsonText)…
To obtain data string like that :
“[{“ReceipNoteId”: 0, “ReceiptNoteNumber”: null, “DeliveryDate”: null, “SiteId”: 0, “SiteName”:“AC0001”, “SupplierName”:“JohnDoe”, “SupplierId”: 0, “DeliveryNumber”: null}]”

Thanks,

I tried above methods by giving null as value but sometimes it will throw an error and sometimes won’t

Hi @Nisha_K21

Please collect all the data into Dictionary

dictJson = New Dictionary(Of String, Object)
dictJson("KeyToBeNull") = Nothing

convert the dictionary to JSON

Newtonsoft.Json.JsonConvert.SerializeObject(dictJson)

Note: Please share your expected form of JSON and will help you with the solutions.

Thanks,
