How to Combine Two Columns in Excel with a Comma: A Simple Guide

Combining two columns in Excel with a comma is a simple task. It involves using a formula to merge the contents of two columns with a comma in between, making it easier to organize and analyze data. You’ll enter a formula in a new column, which will then combine the contents of the selected columns.

How to Combine Two Columns in Excel with a Comma

Combining two columns into one with a comma in Excel can be very useful for data organization and analysis. By following these steps, you’ll learn how to do it quickly and efficiently.

Step 1: Open your Excel file

First, make sure your Excel file is open and that you have the columns you want to combine ready.

Opening your file is as simple as double-clicking on it or using Excel’s "File" menu to locate and open the file. Ensure the columns you want to combine are properly populated with the data you need.

Step 2: Choose a new column

Select a new column where you want the combined data to appear.

This step involves clicking on the first empty cell in the new column where your combined data will be displayed. This column should be empty to avoid overwriting any existing data.

Step 3: Enter the formula

Type in the formula =A1 & ", " & B1 and press Enter.

This formula uses the & operator to concatenate the values in columns A and B with a comma and a space in between. Replace A1 and B1 with the actual cells you are combining if they differ.

Step 4: Copy the formula down

Drag the fill handle (a small square at the bottom-right corner of the cell) down the column to apply the formula to other rows.

Dragging the fill handle allows Excel to apply the same formula to other cells in the column, adjusting the cell references automatically. This ensures all rows in the new column combine the data from the corresponding rows in the original columns.

Step 5: Check your results

Review the combined data to ensure it looks correct.

Take a moment to scan through the new column to verify that the data has combined as expected with commas in the right places. This is a quick quality check to catch any errors.

After completing these steps, your chosen column will show the combined data from the two original columns, separated by commas.

Tips for Combining Two Columns in Excel with a Comma

  • Make sure your data is clean and formatted correctly before combining.
  • Use the TRIM function to remove any extra spaces that may interfere with the merging process.
  • If you’re combining a large dataset, consider using Excel’s “Flash Fill” feature to automate the process.
  • Practice using cell references that automatically adjust as you drag the fill handle.
  • Save your work frequently to avoid losing any changes.

Frequently Asked Questions

What if I want to separate the combined values with something other than a comma?

You can replace the comma in the formula with any delimiter you like, such as a semicolon or a hyphen.

Can I combine more than two columns at once?

Yes, you can extend the formula to include more columns by adding more & "," & between each cell reference.

What if I only want to combine non-empty cells?

You can use an IF statement within your formula to check if the cells are not empty before combining them.

Is there a way to automate this process for a large dataset?

Yes, using Excel’s “Flash Fill” feature can automate the process after you’ve entered the initial combined data.

How can I remove the formula and keep only the values?

You can copy the combined column and then use "Paste Special" > "Values" to keep only the combined data without the formula.


  1. Open your Excel file.
  2. Choose a new column.
  3. Enter the formula.
  4. Copy the formula down.
  5. Check your results.


Combining two columns in Excel with a comma is a straightforward task that can greatly enhance your data management capabilities. With just a few simple steps, you can merge data from multiple columns into a single, more readable format. This process not only saves time but also ensures that your data is consistent and easy to analyze.

Remember to clean your data before combining it and use the TRIM function if necessary to remove any extra spaces. Additionally, Excel’s “Flash Fill” feature can be a lifesaver for larger datasets, automating the process and reducing the chance of errors.

If you’re continually working with data, mastering this simple technique can make your life a lot easier. So go ahead, open up Excel, and start combining those columns like a pro! Happy Excel-ing!
