If you really do need to change the format of the date, parse it into a DateTime format (or Date format if you're using the right version of .NET), and then format the parsed version. The question I would ask, though, is do you really need to change the format? So much time is invested in doing this in backend code when, the majority of the time, a formatted version is just required for the user interface. If that's the case, you shouldn't try to force the format to a particular string; you should use the user locale preferences instead.

You are either using a string value in your JSON, or your ToString needs a format parameter to specify exactly what you want.

So start with the debugger to find out exactly what datatype is in your JSON data as loaded.

The later is simple: Formatting a DateTime for display - format string description[^]

The former is more of a problem, as it means you need to parse the data into a DateTime, and then format it - and that means checking for valid values and potentially handling multiple input formats correctly as well as "empty" values.

I'd suggest that you are possibly handling the JSON data badly: an array implies that you aren't reading the JSON into strongly typed classes so all data has the same type (probably string) and that means you may need to manually process a lot of information to make it actually usable and be sure it's valid.
