# How to Count Columns in Excel with Specific Values

Let’s say we have a large Excel sheet containing sales data for a company. The sheet has over 50 columns, and we need to count how many columns contain sales data for a specific product. This task can be daunting, especially if done manually. However, by using the following functions, we can easily count the number of columns that meet our criteria.

Fortunately, Excel provides several powerful functions that can help you count columns with specific values. In this section, we’ll explore each of these functions in more detail.

## MMULT Function

The MMULT function in Excel is typically used to perform matrix multiplication, but it can also be used to count the number of columns that meet specific criteria. Here’s an example of how to use the MMULT function to count the number of columns that contain sales data for product A:

``=SUM(--(MMULT(--(B2:Z101="Product A"),TRANSPOSE(COLUMN(B2:Z101)^0))>0))``

In this example, we start by specifying the range of cells that contains the sales data (B2:Z101). We then use the “–” operator to convert the Boolean TRUE and FALSE values returned by the comparison operation (B2:Z101=”Product A”) to 1’s and 0’s. We then use the TRANSPOSE function to transpose the resulting matrix so that we can multiply it by the column numbers. The “^0” in the COLUMN function is used to create an array of 1’s of the same size as the transposed matrix. Finally, we use the MMULT function to perform the matrix multiplication and return an array of values. We then use the “>0” operator to convert the resulting Boolean values to 1’s and 0’s, and the SUM function to count the number of columns that contain sales data for product A.

## COLUMN and TRANSPOSE Functions

The COLUMN function in Excel is used to return the column number of a specific cell or range of cells. The TRANSPOSE function is used to transpose a range of cells. Here’s an example of how to use the COLUMN and TRANSPOSE functions to count the number of columns that contain sales data for product A:

``=SUM(--(MMULT(--(B2:Z101="Product A"),TRANSPOSE(COLUMN(B2:Z101:Z101))^0)>0))``

In this example, we specify a range of cells that contains the sales data for the product (B2:Z101=”Product A”). We then use the COLUMN function to return the column number of the last cell in the range (Z101). We wrap the COLUMN function in parentheses to ensure that it returns an array of values rather than a single value. We then use the TRANSPOSE function to transpose the resulting array and use the MMULT function to perform the matrix multiplication. Finally, we use the “>0” operator and the SUM function to count the number of columns that contain sales data for product A.

## BYCOL and LAMBDA Functions

The BYCOL function in Excel is used to apply a function to each column of a range of cells. The LAMBDA function is used to create a user-defined function in Excel. Here’s an example of how to use the BYCOL and LAMBDA Functions:

• Select a cell where you want to display the result.
• Enter the following formula:
``=BYCOL(A1:E5, LAMBDA(column, COUNTIF(column, "specific value")))``

In this formula, A1:E5 is the range of cells that you want to count the columns for, “specific value” is the value that you want to count, and COUNTIF is the function that counts the number of times that the specific value appears in each column.

The LAMBDA function is used to define the function that you want to apply to each column. In this case, the function is COUNTIF(column, “specific value”), which counts the number of times that the specific value appears in the column.

The BYCOL function then applies this function to each column in the range of cells A1:E5 and returns an array of the results.

• Press Enter to calculate the formula and display the result.

This formula will count the number of columns in the range A1:E5 that contain the specific value.

By using the MMULT, COLUMN, TRANSPOSE, BYCOL, and LAMBDA functions in Excel, you can count the number of columns in a range of cells that contain specific values. This method is efficient and accurate and can save you a lot of time when working with large amounts of data.
