I'm struggeling with my JSON file here...
This is what I get from my processing .php-file as a response:

```
{"1":{"Nachname":"Stromberg","Vorname":"Bernd", 
"Benutzername":"strombergbernd12","Password":"Xrz5Bv6A"},
"2":{"Nachname":"Heisterkamp","Vorname":"Ernie", 
"Benutzername":"heisterkampernie12","Password":"aOq24EpF"}}

```

Now, I want to build from this JSON array a csv file. In the first row the csv file should mention the headers Nachname, Vorname, Benutzername and Password and then list in the following rows the rest of the data.

I cant handle that, can you help me?
