Hello, I am creating a CSV table and I would like for each row of the table, there to be a number that increments by 1 in the "Temporaire_ID" field. Can you help me please ?

Re: Increment a variable in a CSV table

Hi @s44

Here is the sample flow:

I have taken an array of objects in the compose action:

[
{
"Name":"Manish Solanki",
"Profile":"Tech Architech"
},
{
"Name":"Arun Solanki",
"Profile":"Owner"
},
{
"Name":"Arnav Solanki",
"Profile":"Student"
}
]

Next, add "Select" action. We will use expression in 'From' parameter to iterate the elements of array. Expression needs to be added in the expression box:

range(0,length(outputs('Compose')))

In Map parameter, enter the below key/value. The Id will the counter of iteration. For value, we will extract the array element by index using expression.

Key Value

Id item()

Name outputs('Compose')?[item()]?['Name']

Profile outputs('Compose')?[item()]?['Profile']

Using, outputs('Compose')?[item()]?['ColumnName/Propery'], we are fetching first fetching the object using index and then passing the name of the property to get its value.

Output:
