When to use Excel COLUMNS Function

Excel COLUMNS function can be used when you want to get the number of columns in a specified range or array.

What it Returns

It returns a number that represents the total number of columns in the specified range or array.

Syntax

=COLUMNS(array)

Input Arguments

• array – it could be an array, an array formula or a reference to a contiguous range of cells.

Additional Notes

• Even if the array contains multiple rows and columns, only the columns are counted. For example:
• COLUMNS(A1:B1) returns 2.
• COLUMNS(A1:B100) also returns 2.
• This formula can be useful when you want to get a sequence of numbers as you go to the right in your worksheet.
• For example, if you want 1 in A1, 2 in B1, 3 in C1 and so on, use the following formula =COLUMNS($A$1:A1). As you would drag this to the right, the reference inside it would change and the number of columns in the reference would get incremented by one. For example, when you drag it to column B1, the formula becomes COLUMNS($A$1:B1) which then returns 2.
