Hello,

I have a result like this  
' values [  
[0] { X = 1  
Y = 2  
Z = 3  
V = 4  
}  
[1] { X = 5  
Y = 6  
Z = 7  
V= 8  
}  
'

How can i read this result and put every value in variable (example Var\_X = Values[0][0] = 1, Var\_Y = Values[0][1] = 2, after that, in the output Block i will inject them in a csv file  
Thank you for your help

It is unclear what result you are looking for. You seem to want

```
"Var_X" => 1
"Var_Y" => 2

```

and I can infer from that what you want for Var\_Z and Var\_V, but what do you want for the second hash in the array?
