## Introduction to COLUMNS Formula

The COLUMNS formula is used to determine the number of columns available in the given array or the reference in the input array. It is an in-built function that comes under the Lookup and Reference function. It is useful in looking for the number of columns in the array.

As an example, let’s assume there is an array “B2:F7” then in the COLUMNS function (=COLUMNS (B2:F7)) will return 5. It means there are 5 columns existing in the range of B2 to F7.

**Syntax **

**COLUMNS () **– It will return the total number of columns available in the given input. There is only one argument – array.

**The Argument in the COLUMNS Function:**

**array****:**It is a mandatory parameter for which the user wants to count the number of columns in the cell range.

Create three headers for the COLUMNS result, rows result, and to show the total cells to show the function result in column D.

Click on cell E2 and apply COLUMNS Formula.

Press the Enter Key.

** **Click on cell E3 and apply ROWS Function to count the total number of rows in the table.

It will then ask for an array that is the range of the table means the total cells in the table, select cells A1 to C10.

Press the Enter Key.

Now just multiply the cells data of the total number of columns and the total number of rows in the E4 to find out the total number of cells in the table.

**‘OR’**

Calculate the total number of columns and the total number of rows in cell E4 and multiply there only.

Press the Enter Key.

**Summary of Example 3: **

As the user wants to find out the total number of cells in the table. The function result is available in cell F4, which is coming 30 after calculation.

**Things to Remember**

- The COLUMNS function will return the number of columns available in the given array or the reference in the input array.
- It can be used in the formula when a user wants to find out the total number of columns available in the array.
- The array argument is allowed even for a single cell or as provided by a reference in the array which has a single cell. But it will not support multiple cells or reference in the columns function; a user can pass a single range at a time.
