Excel CONCATENATE function to combine strings, cells, columns (2024)

Using CONCATENATE in Excel - things to remember

To ensure that your CONCATENATE formulas always deliver the correct results, remember the following simple rules:

• Excel CONCATENATE function requires at least one "text" argument to work.
• In one formula, you can concatenate up to 255 strings, a total of 8,192 characters.
• The result of the CONCATENATE function is always a text string, even when all of the source values are numbers.
• Unlike the CONCAT function, Excel CONCATENATE does not recognize arrays. Each cell reference must be listed separately. For example, you should use CONCATENATE(A1, A2, A3) and not CONCATENATE(A1:A3).
• If any of the arguments is invalid, the CONCATENATE function returns a #VALUE! error.

Concatenate two or more cells without separator

To combine the values of two cells into one, you use the concatenation formula in its simplest form:

=CONCATENATE(A2, B2)

Or

=A2&B2

Please note that the values will be knit together without any delimiter like in the screenshot below.

To concatenate multiple cells, you need to supply each cell reference individually, even if you are combining contiguous cells. For example:

=CONCATENATE(A2, B2, C2)

Or

=A2&B2&C2

The formulas work for both text and numbers. In case of numbers, please keep in mind that the result is a text string. To convert it to number, just multiply CONCATENATE's output by 1 or add 0 to it. For instance:

=CONCATENATE(A2, B2)*1

Tip. In Excel 2019 and higher, you can use the CONCAT function to quickly concatenate multiple cells using one or more range references.

Concatenate cells with a space, comma or other delimiter

In your worksheets, you may often need to join values in a way that includes commas, spaces, various punctuation marks or other characters such as a hyphen or slash. To do this, simply put the desired character in your concatenation formula. Remember to enclose that character in quotation marks, as demonstrated in the following examples.

Concatenating two cells with a space:

=CONCATENATE(A2, " ", B2)

or

=A2 & " " & B2

Concatenating two cells with a comma:

=CONCATENATE(A2, ", ", B2)

or

=A2 & ", " & B2

Concatenating two cells with a hyphen:

=CONCATENATE(A2, "-", B2)

or

=A2 & "-" & B2

The following screenshot demonstrates how the results may look like:

Tip. In Excel 2019 and higher, you can use the TEXTJOIN function to merge strings from multiple cells with any delimiter that you specify.

Concatenating text string and cell value

There is no reason for the Excel CONCATENATE function to be limited to only joining cells' values. You can also use it to combine text strings to make the result more meaningful. For example:

=CONCATENATE(A2, " ", B2, " completed")

The above formula informs the user that a certain project is completed, as in row 2 in the screenshot below. Please notice that we add a space before the word " completed" to separate the concatenated text strings. A space (" ") is also inserted between the combined values, so that the result displays as "Project 1" rather than "Project1".

With the concatenation operator, the formula can be written this way:

=A2 & " " & B2 & " completed"

In the same manner, you can add a text string in the beginning or in the middle of your concatenation formula. For example:

=CONCATENATE("See ", A2, " ", B2)

="See " & A2 & " " & B2

Join text string and another formula

To make the result returned by some formula more understandable for your users, you can concatenate it with a text string that explains what the value actually is.

For example, you can use the following formula to return the current date in the desired format and specify what kind of date that is:

=CONCATENATE("Today is ",TEXT(TODAY(), "mmmm d, yyyy"))

="Today is " & TEXT(TODAY(), "dd-mmm-yy")

Tip. If you would like to delete the source data without affecting the resulting text strings, use the "Paste special - values only" option to convert formulas to their values.

Concatenate text strings with line breaks

Most often, you would separate the resulting text strings with punctuation marks and spaces, as shown in the previous example. In some cases, however, there may be a need to separate the values with a line break, or carriage return. A common example is merging mailing addresses from data in separate columns.

A problem is that you cannot simply type a line break in the formula like a usual character. Instead, you use the CHAR function to supply the corresponding ASCII code to the concatenation formula:

• On Windows, use CHAR(10) where 10 is the character code for Line feed.
• On Mac, use CHAR(13) where 13 is the character code for Carriage return.

In this example, we have the address pieces in columns A through F, and we are putting them together in column G by using the concatenation operator "&". The merged values are separated with a comma (", "), space (" ") and a line break CHAR(10):

=A2 & " " & B2 & CHAR(10) & C2 & CHAR(10) & D2 & ", " & E2 & " " & F2

The CONCATENATE function would take this shape:

=CONCATENATE(A2, " ", B2, CHAR(10), C2, CHAR(10), D2, ", ", E2, " ", F2)

Either way, the result is a 3-line text string:

Note. When using line breaks to separate the combined values, you must have Wrap text enabled for the result to display correctly. To do this, press Ctrl + 1 to open the Format Cells dialog, switch to the Alignment tab and check the Wrap text box.

In the same manner, you can separate final strings with other characters such as:

• Double quotes (") - CHAR(34)
• Forward slash (/) - CHAR(47)
• Asterisk (*) - CHAR (42)

Method 1. Press CTRL to select multiple cells

To quickly select several cells, you can press and hold the Ctrl key while clicking on each cell you want to include in the formula. Here are the detailed steps:

1. Select a cell where you want to enter the formula.
2. Type =CONCATENATE( in that cell or in the formula bar.
3. Press and hold Ctrl and click on each cell you want to concatenate.
4. Release the Ctrl button, type the closing parenthesis, and press Enter.

Note. When using this method, you must click each individual cell. Selecting a range with the mouse would add an array to the formula, which the CONCATENATE function does not accept.

Method 2. Use TRANSPOSE function to get all cell values

When a range consists of tens or hundreds of cells, the previous method may not be fast enough as it requires clicking on each cell. In this case, you can use the TRANSPOSE function to return an array of values, and then merge them together in one fell swoop.

1. In the cell where you want the result to appear, enter the TRANSPOSE formula, for example:

   =TRANSPOSE(A1:A10)

2. In the formula bar, press F9 to replace the formula with calculated values. As a result, you will have an array of values to be concatenated.
3. Delete the curly braces surrounding the array.
4. Type =CONCATENATE( before the first value, then type the closing parenthesis after the last value, and press Enter.

Note. The result of this formula is static as it concatenates the values, not cell references. If the source data changes, you will have to repeat the process.

Method 3. Use the CONCAT function

In Excel 365 and Excel 2021, this simple formula will concatenate a range of cells in a blink:

=CONCAT(A1:A10)

Method 4. Use the Merge Cells add-in

A quick and formula-free way to concatenate any range in Excel is to use the Merge Cells add-in with the "Merge all areas in selection" option turned off, as demonstrated in Combining values of several cells into one cell.

Combine values of several cells into one cell

To combine the contents of several cells, you select the range to concatenate and configure the following settings:

• Under What to merge, select Cells into one.
• Under Combine with, type the delimiter (a comma and a space in our case).
• Choose where you want to place the result.
• Most importantly, uncheck the Merge all areas in the selection box. It is this option that controls whether the cells are merged or their values are concatenated.

Combine columns row-by-row

To concatenate two or more columns, you configure the Merge Cells' settings in a similar way but choose to merge columns into one and place the results in the left column.

Join rows column-by-column

To combine data in each individual row, column-by-column, you choose:

• Merge rows into one.
• Use a line break for the delimiter.
• Place the results in the top row.

The result may look similar to this:
