Now I had the time. Looks great! Thanks for this.
(I had to copy the json files from FPC trunk, it didn't compile with my 2.4 because of "Extract")

This would be great for debugging using ShowMessage or writeln.
Any idea when this feature will be ready?

I have another question.
What exactly is the purpose of TJSONNull in fpjson?

In Javascript, i can do sth. like:

var myJSONObject = 
  "Name": "test",
  "testDate": null

Which I understand as: "There is no date assigned initially, but this can be changed".
I can't figure out how to do this with fpjson. except probably deleting and adding the value/type.

Thank you
