Q: Ever wanted to remove duplicates from an array of line items?
A: Use a Code app as a Zap step: https://zapier.com/apps/code/help

Code step configuration using JavaScript

NOTE: Map your line items array to the right side value for the “Set” Input Data variable in place of “A,B,C,C,B,A”.

Copy the Code

let Set = inputData.Set.split(","); // creates array by splitting Input Data variable at commas

let Distinct = []; // empty array to store the unique values

Set.forEach((i) => {
if (!Distinct.includes(i)) {
Distinct.push(i);
}
});

output = [Set, Distinct}];
