Date and time formate chnaging after reading json and appending to new text file

understood your point .
modified like your suggestion but giving below error cehck ocne

can you share the XAML and a JSON Text sample?

i hve provdied in this link

we do see there the jsons but not the XAML. But it is up to you on what you want to share with us.

Lets recap so far:

  • we had shown on how date parsing can be turned off for the deserialization. so the original string is kept
  • we had shown on how to use it for deserializing a JObject / a JArray

so now just adapt the parts in your XAML and ensure that variables are used with the appropriate datatype. Then we do feel you will get it work
