How to Combine Rows in Excel

There are several ways to combine rows in Excel, depending on what you want to achieve. The simplest method is using the CONCATENATE function or its shorthand & operator to join the contents of cells from different rows into a single cell. However, this only works for combining data from a limited number of pre-selected rows. For more complex row combination, especially involving multiple rows based on criteria or consolidating duplicate rows, more advanced techniques are necessary. These include using Power Query (Get & Transform Data), PivotTables, or VBA macros. Let's explore these options further in relation to the following questions.

Combining Rows Using CONCATENATE or the & Operator

The CONCATENATE function and the & operator are useful for manually combining data from specific rows into a single cell. For instance, if you have data in cells A1, B1, A2, and B2, and you want to combine them into cell C1, you can use the formula =CONCATENATE(A1,B1,A2,B2) or the equivalent =A1&B1&A2&B2. This method is straightforward for simple cases but becomes cumbersome when dealing with a large number of rows or dynamic data. You would need to manually adjust the formula for each combination. Remember to include any necessary separators (e.g., spaces, commas) within the formula to format the combined text appropriately. For example, =A1&" "&B1&" "&A2&" "&B2 adds spaces between the combined data.

Merging Duplicate Rows in Excel While Keeping Unique Data

To merge duplicate rows while retaining unique data, using Power Query (Get & Transform Data) is the most efficient approach. Here's how:

1. Import your data: Select your data range, go to the "Data" tab, and click "From Table/Range." This imports your data into Power Query.
2. Group by: In the Power Query Editor, select the column(s) that define your duplicates. Go to the "Transform" tab and click "Group By."
3. Choose aggregation: Specify the column(s) you want to group by and select the aggregation function for the remaining columns. For example, if you have a column with duplicate names and want to combine their corresponding addresses, you would group by "Name" and choose an aggregation function like "All Rows" to list all addresses associated with that name in a single cell within the grouped row. For numerical data, you might use "Sum," "Average," "Max," or "Min" as appropriate.
4. Expand the table: If you chose "All Rows" as the aggregation, you might have a table within a cell. You will need to expand this table to get the individual values back into their own columns.
5. Close & Load: Click "Close & Load" to bring the transformed data back into your Excel sheet.

This method effectively merges duplicate rows while retaining all unique information associated with each duplicate group.

The Best Excel Function for Concatenating Data from Multiple Rows into a Single Cell

While CONCATENATE or & can be used, they are not ideal for dynamically combining data from multiple rows. For this, the TEXTJOIN function (available in Excel 2019 and later) is superior. TEXTJOIN allows you to specify a delimiter and ignore empty cells, making it much more versatile and efficient. For example, if you want to combine the values in cells A1:A10 into a single cell with commas as separators, you would use =TEXTJOIN(",",TRUE,A1:A10). The TRUE argument indicates that empty cells should be ignored. This function greatly simplifies concatenating data across multiple rows compared to manually using CONCATENATE or & for a large number of cells.

Combining Rows Based on a Specific Column Value in Excel

Again, Power Query provides the most robust solution for this. Similar to merging duplicate rows, you would use the "Group By" function in Power Query. This time, however, you group by the specific column containing the values you want to use as criteria for combining rows. The aggregation function will determine how the data from other columns is combined within each group (e.g., using "All Rows" to list all associated data). Alternatively, you could use PivotTables, which offer a visual way to summarize data based on specified column values. However, for complex scenarios or the need for precise control over the combination process, Power Query generally provides more flexibility and power.
