Efficiently Looping Through Multiple Arrays in VBA

When working with multiple arrays in VBA, one common challenge is how to efficiently loop through them and display their values in a structured format. As you accumulate more arrays, managing them can become cumbersome if you aren’t using the right techniques.

In this post, we will explore two effective methods to loop through arrays in VBA, enabling you to display values effortlessly without resorting to repetitive coding.

Problem Overview

Consider the following example arrays:

Numbers (num): (1, 2, 3)

Names (name): (Tesa, John, Mike)

Tags (tag): (tag1, tag2, tag3)

Desired Output:

The output we want to achieve from these arrays is as follows:

The challenge arises when you realize that manually coding for each individual entry can lead to inefficiency, especially when scaling up with more arrays.

Solution Breakdown

Let’s dive into two distinct solution approaches for looping through these multiple arrays.

Option 1: Using Array() Function

In this method, we will take advantage of the Array() function to create our arrays and loop through them using a simple For loop.

Here’s how you can do it:

Explanation:

UBound(Num): This function obtains the upper boundary of the Num array, allowing us to loop through all its indices.

Join Function: Combines the items into a single string separated by .... for clearer output.

Option 2: Using Collection with Array()

For a more flexible approach, consider using a Collection. This method allows you to add any number of arrays dynamically without hardcoding the references.

Here’s how to implement it:

Explanation:

Collection: Used to store arrays. You can add as many arrays as you want without modifying your code further.

Dynamic Array Size: ReDim allows you to declare the size of the output array a based on the number of arrays stored in the collection.

Output Results

Both methods will yield the following output in your VBA console:

Conclusion

Looping through multiple arrays in VBA doesn't have to be tedious. With the techniques outlined above, you can significantly reduce the complexity and potential for errors when modifying your sets of data.

Feel free to experiment with these methods based on your needs and scale your arrays without worrying about increasing your code's redundancy or clutter.

Happy coding!
