Introduction
In this article, we will explore the fascinating world of sorting in pivot tables and data models. Specifically, we will focus on the difference between sorting months alphabetically and chronologically in tools like Excel, Power Pivot, and Power BI. We will discover how custom lists in Excel play a role in sorting, the challenges that arise when using power pivot-based pivot tables, and the powerful technique of sorting by another column. By understanding these concepts, you can gain better control over your data analysis, reporting, and visualization tasks.
🔍💡
Understanding Pivot Tables in Excel
Before diving into the intricacies of sorting, let's first establish a clear understanding of what pivot tables are. Pivot tables, available in Excel and other data analysis tools, allow you to summarize and analyze large datasets quickly. They provide a flexible way to extract meaningful insights and answer complex questions from your data.
💡
Sorting Months Alphabetically vs. Chronologically
One common challenge when working with pivot tables is sorting months correctly. By default, Excel sorts months alphabetically, which may not always align with our expectations. For instance, when analyzing time series data, we typically want the months to be sorted chronologically. However, there is a reason behind Excel's default sorting behavior, and it can be addressed with the right approach.
⚖️
Behind the Scenes: Custom Lists in Excel
To understand Excel's default sorting behavior, we need to look behind the scenes. Excel maintains a set of custom lists that determine the order of sorting for certain values, including months. These lists can be found in the Excel options under the Advanced settings. By leveraging these custom lists, Excel provides the ability to sort data in specific orders based on predefined rules.
🔍💡
Sorting in Power Pivot and Power BI
When working with power pivot-based pivot tables or using tools like Power BI, the sorting behavior changes. Unlike Excel, these tools do not consider custom lists for sorting. As a result, the sorting becomes alphabetical by default, irrespective of the chronological order of months. This shift in behavior can be puzzling for Excel users transitioning to power pivot-based solutions.
⚠️
The Magic of Sorting by Another Column
However, there is a solution to this sorting dilemma. By leveraging the power of sorting by another column, you can regain control of your sorting preferences. To implement this technique, you need to define a separate column in your data model that represents the desired sort order. For example, you can create a month number column alongside the month name column. By sorting the month names based on their corresponding numbers, you can achieve the desired chronological order.
✨
Applying Sorting to Analysis and Reporting
The ability to sort by another column opens up a world of possibilities for your data analysis and reporting tasks. For example, in competitive analysis, you may want to sort products or competitors in a specific order. Similarly, in geographical analysis, you may need to sort regions based on predefined criteria. Sorting by another column empowers you to customize the order of your data, making your analysis and reporting more insightful and user-friendly.
💡💡
Sorting in Charts and Visualizations
Sorting also plays a crucial role in data visualizations, particularly when creating charts. Imagine you want to highlight a specific category in your chart, such as the third column. By ensuring that the desired category retains its position through sorting, you can consistently highlight it across different visualizations. Sorting by another column allows you to maintain the positioning of data points and enhance the clarity and effectiveness of your charts.
📊✨
Sorting in Other Data Models
While we have primarily focused on power pivot-based solutions, the concept of sorting by another column is applicable to various data models. Whether you are working with different software tools or building custom data models, the technique remains the same. By leveraging an additional column for sorting purposes, you can ensure that your data is arranged in a meaningful and logical manner, regardless of the specific data analysis tool or environment.
🔧
Conclusion
Sorting is a fundamental aspect of data analysis and reporting. Understanding the differences in sorting behavior between Excel, Power Pivot, and Power BI is essential for leveraging the full potential of these tools. By harnessing the technique of sorting by another column, you can regain control over sorting preferences and enhance the accuracy and clarity of your data analysis, reporting, and visualizations. So, embrace the power of sorting and unlock new insights from your data.

FAQs
Q: Can I sort months chronologically in Excel without using custom lists?
A: Excel sorts months alphabetically by default. However, you can achieve chronological sorting by creating a separate column with numerical values representing the months and then sorting the original month names based on this column.
Q: Does sorting by another column affect the original data?
A: Sorting by another column in tools like Excel, Power Pivot, and Power BI does not change the original data. It only affects the sorting order within the specific analysis or visualization.
Q: Can I apply sorting by another column to other types of data, not just months?
A: Yes, the technique of sorting by another column can be applied to various types of data beyond months. It allows you to define a custom sorting order based on any specific criteria or preferences you have.
Q: Are there any limitations to sorting by another column?
A: Sorting by another column is a powerful technique but may have limitations depending on the complexity of your data model or the software tool you are using. It is important to consider the compatibility and functionality of the tool to ensure the desired sorting behavior is achieved.
Q: How can I learn more about sorting in pivot tables and data models?
A: To deepen your knowledge of sorting in pivot tables and data models, you can explore online tutorials, forums, and documentation specific to the software tools you are using, such as Excel, Power Pivot, or Power BI. Additionally, experimenting with different scenarios and practicing hands-on will enhance your understanding and proficiency in this area.
