Hi,

Is it possible to filter a 2D array using the "Filter Array" action?

I have an array, please see below.

[
 {
 "IDNumber": "1",
 "FullName": "Debbie Lob",
 "Department": "Finance",
 "Email": "debbie.lob@example.com"
 },
 {
 "IDNumber": "2",
 "FullName": "John Mills",
 "Department": "Finance",
 "Email": "john.mills@example.com"
 },
 {
 "IDNumber": "3",
 "FullName": "Mary David",
 "Department": "IT",
 "Email": "mary.david@example.com"
 }
]

How can I filter these data? Sample, I would like to get the "FullName" with "IDNumber" equals to "1"? The output should be "Debbie Lob"

These data are stored in an array variable named "NamesArray".

Thanks,

Chng

Hi @ching29,

I have a way to get the value you want.
Use Apply_to_each to iterate over the array and then use to get the properties inside each object.
Initialize two variables, an array, and a value that holds the output.

Traverse the array, get the element with the IDNumber equal to 1, and then take the desired value. Then store it in the String variable and finally output it.
The red part is Expression, not directly populated in the field.
