In this article, we will explore a solution to the problem of listing all possible combinations of six numbers from 1 to 44, which is commonly encountered in lottery scenarios. We will discuss how Excel's limitations make it necessary to use VBA (Visual Basic for Applications) to overcome them and efficiently generate the desired combinations. Through step-by-step explanations and code demonstrations, you will learn how to implement this solution and adapt it for different lottery systems. So, let's dive in and explore the world of lottery combinations in Excel!

Understanding the Problem

In order to effectively solve the problem at hand, it is important to first understand its intricacies. The task is to generate a list of all possible combinations of six numbers chosen from a pool of 44 numbers. This means that each combination should consist of six unique numbers, ranging from 1 to 44. For example, a valid combination could be 1-2-3-4-5-6, while another could be 1-2-3-4-5-7. It is important to note that the order of the numbers within a combination is not significant, and repetitions are not allowed.

Excel's Limitations

A major challenge in generating these combinations is the sheer number of possibilities. With 44 numbers to choose from, selecting six at a time results in 7,059,052 distinct combinations. Unfortunately, Excel has a limitation on the number of rows it can handle, allowing only up to 1,048,576 rows. Therefore, a straightforward approach of populating each combination in a separate row in Excel is not feasible. However, we can overcome this limitation by utilizing VBA, which offers more flexibility and efficiency.

Using VBA for Efficiency

VBA (Visual Basic for Applications) is a programming language that comes built-in with Excel. It allows us to automate tasks and create custom solutions that go beyond the limitations of Excel's standard functionality. In our case, we will use VBA to generate the list of lottery combinations efficiently, leveraging its looping and conditional logic capabilities.

Setting Up the Code

To begin with, we need to set up the VBA code that will generate the combinations. Since VBA is an integrated part of Excel, we can access it by following a few simple steps. Firstly, we need to enable the Developer tab in Excel's ribbon. To do this, right-click anywhere on the ribbon, select "Customize the Ribbon," and check the box next to "Developer." This will make the Developer tab visible.

Once the Developer tab is visible, click on it and navigate to the "Visual Basic" button. This will open the Visual Basic Editor, where we can write and edit our VBA code. In the Project Explorer window, find and expand the workbook containing the lottery combination data. Right-click on the workbook, select "Insert," followed by "Module." This will create a new module, where we will write our code.

Looping through the Combinations

Now that we have our code module set up, we can start writing the VBA code to generate the combinations. The central idea here is to use nested loops to iteratively select each number in the combination, ensuring that it is higher than the preceding numbers. We will use variables to represent each of the numbers in the combination, and increment them within the loops. The outermost loop will represent the first number (A), followed by subsequent loops for the remaining numbers (B, C, D, E, and F).

For example, within the nested loops, we will start with A = 1 and loop through B = 2 to 40 (one number higher than A). Then, within this B loop, we will run C from 3 to 41 (one number higher than B), followed by D from 4 to 42, E from 5 to 43, and finally F from 6 to 44. By changing the values of A, B, C, D, E, and F within their respective loops, we cover all possible combinations.

Tracking Progress and Saving

Given the large number of combinations, generating them all at once can be time-consuming. To keep track of the progress and ensure that the code is working as expected, we can use a counter variable. By incrementing the counter within the loop, we can periodically check its value and save the workbook to see the current progress. This helps ensure that the code is functioning correctly and provides a sense of reassurance during the lengthy generation process.

Testing the Macro

Before running the macro for the complete set of combinations, it is advisable to test it with a smaller sample. This allows us to verify that the code is working properly and to gauge the execution speed. In our example, we can limit the generation to the first 25,000 combinations. By setting up a breakpoint and running the code, we can observe its progress and confirm that the expected combinations are being generated.

After confirming the successful generation of the initial 25,000 combinations, we can proceed to remove the breakpoint and allow the macro to run for the full set of combinations. Depending on the speed of your computer and the version of Excel being used, the complete generation process may take considerable time. It is important to be patient and let the code run its course without interruptions.

Adapting for Different Lotteries

The solution we have described thus far is specific to the problem of generating lottery combinations using six numbers chosen from a pool of 44. However, it can be easily adapted to cater to different lotteries with varying requirements. For instance, if your lottery involves selecting five numbers from 1 to 69 and an additional "Powerball" number from 1 to 26, you can modify the code accordingly.

By adjusting the range and number of loops within the VBA code, you can accommodate any lottery system. For example, you can create separate loops for the main numbers (A through E) and a final loop for the Powerball number (F). This flexibility enables you to extend the solution to meet the specific criteria of your lottery and generate the desired combinations.

Additional Resources

If you are interested in further exploring VBA and macros in Excel, there are numerous resources available to enhance your skills. One such resource is the book "Excel 2016 VBA and Macros" written by Tracy and Bill Jelen (also known as MrExcel). Although this book focuses on Excel 2016, subsequent versions such as 2019 and 2021 are similar in terms of VBA functionality. This resource provides in-depth explanations and examples to help you master VBA and leverage its capabilities to automate tasks and create efficient solutions.


In this article, we have explored the problem of listing all possible combinations of six numbers from 1 to 44 for lottery purposes. We have discussed the limitations of Excel and the need to utilize VBA for efficient generation of these combinations. Through step-by-step explanations and code demonstrations, you have learned how to set up the VBA code, loop through the combinations, track progress, and adapt the solution for different lotteries. By employing the techniques outlined in this article, you can efficiently generate and manage lottery combinations in Excel.
