Handling JSON DateTime format on Asp.Net Core

This is a very simple trick to handle JSON date format on AspNet Core by global settings. This can be applicable for the older version as well.

In a newer version by default, .Net depends upon Newtonsoft to process any JSON data. Newtonsoft depends upon Newtonsoft.Json.Converters.IsoDateTimeConverter class for processing date which in turns adds timezone for JSON data format.

There is a global setting available for same that can be adjusted according to requirement. So, for example, we want to set default formatting to US format, we just need this code.

       services.AddMvc()  
       .AddJsonOptions(options =>  
       {  
         options.SerializerSettings.DateTimeZoneHandling = "MM/dd/yyyy HH:mm:ss";  
       });
