Hi there,

Let’s say I have a variable that is a json array with objects that consists of key/value.

[  
{  
“Key”: “item1”  
“Value”: “value of item 1”  
},  
{  
“Key”: “item2”  
“Value”: “value of item 2”  
}  
]

So for example: How do I get the value where key = “item2”

Thanks in advance.

You can use the `lookup` formula un der the array section:

Great. More efficient then a combination of filterbykey and getkeyvalue. And good to see that that dot notation to fetch the value of value key works. I will try this out.
