Excel CHOOSECOLS Function

When to Use the Excel CHOOSECOLS Function in Excel

Excel CHOOSECOLS function is an invaluable tool that allows you to select and extract specific columns from a range of data. This function is particularly useful when you need to manipulate data, create customized views of your data, or perform calculations based on selected columns.

What Excel CHOOSECOLS Function Returns

The Excel CHOOSECOLS function returns a new range that consists of the selected columns from the input data array.

Syntax of Excel CHOOSECOLS Function

The correct syntax for the Excel CHOOSECOLS function is as follows:

=CHOOSECOLS(array, col_num1, [col_num2], …)

Input Arguments

Here are the input arguments for the Excel CHOOSECOLS function:

● array: The array represents the source data from which you want to extract columns. It can be a reference to a cell range containing your data or a named range.

● col_num1, [col_num2], …: These are positive integers that indicate which columns you want to select from the data array. You can specify one or more column numbers separated by commas.

Extra Notes

● If the number you put in the col_num argument is zero or goes beyond the total number of columns in your data, it will give you a #VALUE error.

● The order of the selected columns in the returned range matches the order in which they are specified in the col_num arguments.

Here are few examples of using the Excel CHOOSECOLS function in Excel:

Example 1: Basic Usage

Suppose you have a dataset, and you want to extract specific columns. You can do this using the following formula:

Here’s a breakdown of how it works: =CHOOSECOLS(A1:G5, 1, 3, 7)

• A1:G5: This is the dataset or data range from which you want to extract columns. It consists of 7 columns.
• 1, 3, 7: These are the column numbers you want to extract from the data range.

So, the result of this formula would be a new range that contains only columns 1, 3, and 7 from the original data range A1:G5. The order of the selected columns in the result matches the order in which they are specified in the formula.

Now, let’s observe the outcome when we specify the same column number more than once in the formula for the Excel CHOOSECOLS function.

In the example above, you can observe that we included the fifth column twice, resulting in its duplication in the output.

Now, let’s find out what occurs when we put a negative value in the column number argument, and how it affects the result.

The formula =CHOOSECOLS(A1:G5, 1, -2) in Excel extracts the first column and the column that is two positions from the end in the dataset defined by the range A1:G5. When using a negative value like -2, it counts columns from the end of the range.

Now, let’s see if we can arrange the column numbers in reverse order, such as =CHOOSECOLS(A1:G5, 6, 2, 3).

So, in the above example, you can observe that you have the freedom to arrange the column numbers in any order you prefer.

Example 2: Extract Columns from Various Ranges.

If you want to grab specific columns from different ranges that are not next to each other, you can start by combining all the ranges into a single one using the Excel VSTACK function. After that, you can work with the combined range using Excel CHOOSECOLS function.

The formula =CHOOSECOLS(VSTACK(A3:D6, A10:D12, A16:D18), 1, 3) in Excel does the following:

VSTACK Function: It combines data from three non-contiguous ranges (A3:D6, A10:D12, A16:D18) into a single continuous range.

CHOOSECOLS Function: It selects and extracts specific columns from the combined range. In this case, it retrieves the first column (Name) and the third column (Science) from the merged data.

Frequently Asked Questions (FAQs)

Q1: Can the CHOOSECOLS function select columns from multiple data arrays?

A1: No, the CHOOSECOLS function works with a single data array at a time. If you need to select columns from multiple data arrays, you can merge the data using the Excel VSTACK function and then apply the Excel CHOOSECOLS function.

Q2: Can the CHOOSECOLS function reorder the selected columns in the output range?

A2: No, the CHOOSECOLS function returns the selected columns in the same order as they are specified in the col_num arguments.

Q3: What happens if I specify duplicate column numbers in the col_num arguments?

A3: If you specify the same column number more than once in the col_num arguments, the CHOOSECOLS function will indeed duplicate the column in the output range. Each occurrence of the same column number will result in that column being included again in the output range.

Q4: Can the CHOOSECOLS function be used to filter data based on specific conditions?

A4: No, the CHOOSECOLS function is for selecting columns only. If you need to filter data based on conditions, you should use other functions like FILTER or advanced filtering techniques in Excel.
