When working with data in Google Sheets, it’s not uncommon to find yourself with columns that contain duplicate or redundant information. In such cases, merging two columns can be a crucial step in cleaning and organizing your data. Merging columns can help you reduce data redundancy, make your data more readable, and even enable you to perform more advanced analysis and visualization. In this blog post, we’ll explore the process of merging two columns in Google Sheets, covering the various methods and techniques you can use to achieve this goal.
Merging Columns: Why and When
Merging columns is an essential data manipulation technique that can be applied in a wide range of scenarios. Here are some common reasons why you might want to merge two columns:
- You have duplicate data in two columns, and you want to remove the duplicates and keep only one instance of the data.
- You have two columns with similar information, and you want to combine them into a single column for easier analysis or visualization.
- You have a column with multiple values separated by commas or other delimiters, and you want to split the values into separate columns.
- You have a column with dates or times in a specific format, and you want to convert them to a standard format for easier analysis.
Merging Columns Using the Concatenate Function
One of the most common methods for merging two columns in Google Sheets is using the Concatenate function. This function allows you to combine the values in two columns into a single column. Here’s how to do it:
- Select the cell where you want to merge the columns.
- Type “=concat(A1,B1)” (assuming the columns you want to merge are in columns A and B).
- Press Enter to apply the formula.
The Concatenate function will combine the values in cells A1 and B1 into a single string. You can also use the Concatenate function to merge multiple columns by adding more columns to the formula, separated by commas. For example:
=concat(A1,B1,C1)
Customizing the Concatenate Function
By default, the Concatenate function will combine the values in the two columns using a space character as the delimiter. However, you can customize the delimiter by adding a third argument to the formula. For example:
=concat(A1,B1,”-“)
This will combine the values in cells A1 and B1 using a hyphen (-) as the delimiter.
Merging Columns Using the Text Join Function
Another method for merging two columns in Google Sheets is using the Text Join function. This function allows you to combine the values in two columns into a single column, using a specific delimiter. Here’s how to do it: (See Also: How to Tell Google Sheets to Round Up? Easily!)
- Select the cell where you want to merge the columns.
- Type “=textjoin(“-“,true,A1:B1)” (assuming the columns you want to merge are in columns A and B).
- Press Enter to apply the formula.
The Text Join function will combine the values in the two columns using a hyphen (-) as the delimiter. You can customize the delimiter by replacing the hyphen with any other character or string. For example:
=textjoin(“,”,true,A1:B1)
This will combine the values in cells A1 and B1 using a comma (,) as the delimiter.
Using the Text Join Function with Multiple Columns
You can also use the Text Join function to merge multiple columns by adding more columns to the formula, separated by commas. For example:
=textjoin(“-“,true,A1:C1)
This will combine the values in cells A1, B1, and C1 into a single string, using a hyphen (-) as the delimiter.
Merging Columns Using the Array Formula
Another method for merging two columns in Google Sheets is using an array formula. This method allows you to merge the values in two columns into a single column, using a specific delimiter. Here’s how to do it:
- Select the cell where you want to merge the columns.
- Type “=arrayformula(concatenate(A1:A10,B1:B10))” (assuming the columns you want to merge are in columns A and B, and you want to merge the values in rows 1 to 10).
- Press Ctrl+Shift+Enter to apply the array formula.
The array formula will combine the values in the two columns using a space character as the delimiter. You can customize the delimiter by adding a third argument to the formula. For example: (See Also: How to Make Lowercase in Google Sheets? Easy Tricks)
=arrayformula(concatenate(A1:A10,B1:B10,”-“))
This will combine the values in cells A1 to A10 and B1 to B10 using a hyphen (-) as the delimiter.
Using the Array Formula with Multiple Columns
You can also use the array formula to merge multiple columns by adding more columns to the formula, separated by commas. For example:
=arrayformula(concatenate(A1:C1))
This will combine the values in cells A1, B1, and C1 into a single string, using a space character as the delimiter.
Conclusion
Merging two columns in Google Sheets can be a powerful way to clean and organize your data, and there are several methods you can use to achieve this goal. In this blog post, we’ve covered three methods for merging columns: using the Concatenate function, using the Text Join function, and using an array formula. Each method has its own advantages and disadvantages, and the best method for you will depend on your specific needs and requirements. By mastering these methods, you can take your data analysis and visualization skills to the next level and unlock new insights and opportunities.

Frequently Asked Questions
Q: How do I merge two columns in Google Sheets?
A: You can merge two columns in Google Sheets using the Concatenate function, the Text Join function, or an array formula. The method you choose will depend on your specific needs and requirements.
Q: How do I customize the delimiter when merging columns?
A: You can customize the delimiter when merging columns by adding a third argument to the Concatenate function or the Text Join function. For example, you can use the Concatenate function to combine the values in two columns using a hyphen (-) as the delimiter.
Q: How do I merge multiple columns in Google Sheets?
A: You can merge multiple columns in Google Sheets by adding more columns to the formula, separated by commas. For example, you can use the Concatenate function to combine the values in three columns using a space character as the delimiter.
Q: How do I merge columns in Google Sheets using an array formula?
A: You can merge columns in Google Sheets using an array formula by typing “=arrayformula(concatenate(A1:A10,B1:B10))” and pressing Ctrl+Shift+Enter. This will combine the values in the two columns using a space character as the delimiter.
Q: How do I undo a merged column in Google Sheets?
A: You can undo a merged column in Google Sheets by selecting the cell where the merged column was created and pressing Ctrl+Z. This will restore the original values in the two columns.
