Imagine you're tasked with analyzing two datasets—one containing a list of products and another with customer segments. How do you uncover every possible pairing to identify untapped opportunities? Manually creating combinations might seem feasible for a few rows, but what if each table contains hundreds of entries? The process quickly becomes overwhelming, prone to errors, and a major drain on your time. Fortunately, Excel's dynamic array formulas offer a innovative solution. By using advanced tools like SEQUENCE, LET, and HSTACK, you can automate this task, generating all possible combinations effortlessly while making sure accuracy and adaptability. This isn't just a productivity boost—it's a smarter way to approach data analysis.
In this feature, Excel Off The Grid explain how to harness Excel's most powerful functions to dynamically combine data from two tables, regardless of their size or complexity. You'll learn how to use SEQUENCE to create numeric frameworks, MOD and QUOTIENT to structure patterns, and CHOOSEROWS to extract precise rows—all culminating in a seamless, automated workflow. Whether you're pairing employees with projects, matching products with markets, or conducting scenario analysis, these techniques will unlock new possibilities in your data management. By the end, you won't just know how to create combinations—you'll understand how to transform Excel into a tool that works for you, not the other way around. Excel Table Combination Guide The Importance of Dynamic Array Formulas
Dynamic array formulas are the foundation of this method, allowing calculations across entire arrays of data without requiring manual intervention. Among these, the LET function is particularly powerful, as it allows you to define reusable variables within a formula. This capability simplifies complex calculations by breaking them into smaller, more manageable components. For instance, you can use LET to define variables for row indices or patterns, which can then be applied to extract and combine data efficiently. By reducing formula complexity, LET enhances both readability and functionality, making it easier to adapt the solution to different datasets. Generating Combinations with SEQUENCE
The SEQUENCE function plays a critical role in creating the numeric framework necessary for pairing rows from two tables. It generates a series of numbers that represent all possible combinations of rows. For example, if Table 1 contains three rows and Table 2 has four rows, SEQUENCE can produce a series from 1 to 12, representing every possible pairing. This numeric sequence serves as the backbone for organizing and merging data from the two tables. By automating this step, SEQUENCE eliminates the need for manual calculations, making sure that the process is both scalable and error-free. How to Pair Data from Two Excel Tables in 2025

To systematically align data from two tables, it is essential to create repeating and grouped patterns. The MOD function is used to generate repeating patterns by dividing numbers and returning the remainder. This is particularly useful for cycling through rows in one table. On the other hand, the QUOTIENT function divides numbers and returns the integer part, which is ideal for grouping rows from the other table. When combined, these functions create a structured pattern that ensures data from both tables is aligned seamlessly. This structured approach not only simplifies the process but also ensures accuracy when working with large datasets. Combining Data with CHOOSEROWS and HSTACK
Once the patterns are established, the CHOOSEROWS function is used to extract specific rows from each table based on the generated indices. This ensures that the combinations are accurate and dynamic, even when the underlying data changes. The HSTACK function then merges the selected rows from both tables into a single array. The result is a comprehensive table containing all possible combinations, ready for further analysis or reporting. This combination of functions ensures that the process is both efficient and adaptable, allowing you to focus on deriving insights rather than managing data manually. Adapting to Dynamic Updates
One of the most significant advantages of this approach is its flexibility. When new data is added to either table, the formulas automatically recalculate to include the updates. This eliminates the need for manual adjustments, saving time and reducing the risk of errors. By using dynamic array functions, you can ensure that your combination table remains accurate and up-to-date, regardless of how your data evolves. This adaptability makes the method particularly valuable for scenarios where data is frequently updated or expanded. Applications and Advantages
This method is especially useful in situations where relationships between two datasets need to be explored or analyzed. Practical applications include: Pairing products with customer segments to identify potential marketing opportunities
Matching employees with projects to optimize resource allocation
Exploring combinations of variables for testing, modeling, or scenario analysis
Automating the creation of these combinations not only improves productivity but also allows you to focus on deriving actionable insights. Additionally, using advanced formulas like LET, SEQUENCE, MOD, and HSTACK demonstrates Excel's versatility as a tool for handling complex data manipulation tasks. This approach enables users to streamline workflows, reduce errors, and achieve more accurate results. Optimizing Your Workflow with Advanced Excel Functions
By combining dynamic array formulas with advanced Excel functions, you can efficiently generate all possible combinations from two tables. Tools like LET, SEQUENCE, MOD, QUOTIENT, CHOOSEROWS, and HSTACK ensure that the process is both structured and adaptable. This approach not only saves time but also provides a scalable solution for dynamic data analysis. Whether you are working with small datasets or large tables, these techniques enable you to automate and optimize your workflows, making Excel an even more powerful tool for data management and analysis.
