Merge Two Columns in Excel: A Step-by-Step Guide
Merging two columns in Excel is a common task that can be accomplished in a few different ways, depending on the desired outcome and the version of Excel you're using. Whether you're a seasoned Excel user or just starting out, this guide will walk you through the process of merging two columns using the most common methods.
Why Merge Columns in Excel?
Merging columns in Excel can be useful in a variety of situations, such as:
- Combining names and titles in a contacts list
- Creating a single column for addresses
- Merging data from multiple columns into a single column for analysis
By merging columns, you can reduce data clutter, make your spreadsheets easier to read and use, and improve data analysis and reporting.

Merging Columns Using the Concatenate Function
The most straightforward way to merge two columns in Excel is to use the CONCATENATE function. This function combines text strings from two or more cells into a single cell.
To use the CONCATENATE function, follow these steps:
- Select the cell where you want to merge the columns
- Go to the formula bar and type "=CONCATENATE(A1:B1)" (assuming the columns you want to merge are in cells A1 and B1)
- Press Enter to apply the function
Alternatively, you can use the "&" symbol to concatenate the values from two cells, like this: "=A1&B1". This method is quicker and easier, but less flexible than the CONCATENATE function.

Merging Columns Using the Ampersand (&) Symbol
An alternative to the CONCATENATE function is to use the "&" symbol to merge two columns. This method is quicker and easier, but less flexible.
To use the "&" symbol, follow these steps:
- Select the cell where you want to merge the columns
- Type "=" followed by the "&" symbol
- Type the cell reference for the first column, followed by the "&" symbol and the cell reference for the second column
- Press Enter to apply the function
For example, if you want to merge columns A and B, you would type "=A1&B1".
Merging Columns Using the Flash Fill Feature (Excel 2013 and Later)
Excel 2013 and later versions offer a feature called Flash Fill, which allows you to quickly merge two columns with similar data by copying and pasting the data into a new column.
To use the Flash Fill feature, follow these steps:
- Select the cells that contain the data you want to merge
- Copy the cells by pressing Ctrl+C (or Cmd+C on a Mac)
- Right-click on the cell where you want to merge the columns and select "Flash Fill"
- Excel will automatically create a new column with the merged data
Merging Columns Using a Formula (Excel 2010 and Earlier)
If you're using an earlier version of Excel, you can still merge two columns using a formula.
To use a formula to merge two columns, follow these steps:
- Select the cell where you want to merge the columns
- Go to the formula bar and type "=CONCATENATE(A1,": (assuming the columns you want to merge are in cells A1 and A2)
- Drag the formula down to the other cells in the column
Alternatively, you can use the "&" symbol to concatenate the values from two cells, like this: "=A1&A2".
Tips and Variations
Here are some additional tips and variations to keep in mind when merging columns in Excel:
- Use the CONCATENATE function with multiple arguments to merge more than two columns
- Use the "&" symbol with multiple cell references to concatenate multiple cells
- Use the Flash Fill feature to quickly merge columns with similar data
- Use a formula to merge columns when you need to perform more complex operations, such as concatenating values with different data types
By following these steps and tips, you can quickly and easily merge two columns in Excel, regardless of the version you're using or the complexity of your data.
