How to Merge Collections in PowerApps Using AddColumns: A Comprehensive Guide!

Welcome to the ‘Merge PowerApps Collections Guide: A Comprehensive Journey.‘ This guide is dedicated to exploring the intricacies of merging collections in PowerApps using the AddColumns function. This essential technique is pivotal for enhancing data visibility and efficiency by seamlessly joining multiple columns. Our focus will be on the multi-column method within PowerApps to achieve efficient data amalgamation, offering a detailed, step-by-step approach for better comprehension and implementation.

Initial Collections

Let’s consider two sample collections for this demonstration:


ProductID      QuantitySold
  1001              4
  1002              5
  1001              7
  1000              1
  1000              8


ProductID    ProductName    UnitPrice    Stock
  1000         Jacket          70          10
  1001         T-Shirt         30          4
  1002         Baseball Cap    20          8

Desired Output

After joining the columns, our desired output collection, named myMergedData, will look something like this:

ProductID    QuantitySold    ProductName      UnitPrice     InStock
  1001            4             T-Shirt           30           4
  1002            5             Baseball Cap      20           8
  1001            7             T-Shirt           30           4
  1000            1             Jacket            70           10
  1000            8             Jacket            70           10


Here’s the PowerApps solution code to achieve the above results:

// Initialize two collections
{ProductID: "1000", 'ProductName': "Jacket", UnitPrice: 70},
{ProductID: "1001", 'ProductName': "T-Shirt", UnitPrice: 30},
{ProductID: "1002", 'ProductName': "Baseball Cap", UnitPrice: 20}

{ProductID: "1001", QuantitySold: 4},
{ProductID: "1002", QuantitySold: 5},
{ProductID: "1001", QuantitySold: 7},
{ProductID: "1000", QuantitySold: 1},
{ProductID: "1000", QuantitySold: 8}

// Code to join columns from another collection
