## Part 1: How to Compare Two Columns in Google Sheets - Using 3 Common Functions

Here is a step-by-step tutorial on how to compare two columns in Google Sheets using 3 common functions:

Function 1: COUNTIF Function

The COUNTIF function is used to count the number of cells in a range that match a specific criterion. You can use this function to compare two columns by counting the number of cells in one column that match the values in the other column.

Step 1: Enter your data into two columns in your Google Sheet. For example, let's say you have a list of customers and their corresponding purchase amounts in columns A and B.

Step 2: In a new column, enter the following formula:

=COUNTIF(A:A, B2)

This formula will count the number of cells in column A that match the value in cell B2.

Step 3: Copy the formula down to the rest of the cells in the column. This will calculate the number of matches for each customer.

Function 2: VLOOKUP Function

The VLOOKUP function is used to look up a value in one column and return the corresponding value from another column. You can use this function to compare two columns by finding the corresponding value in one column for each value in the other column.

Step 1: Enter your data into two columns in your Google Sheet. For example, let's say you have a list of customers and their corresponding email addresses in columns A and B.

Step 2: In a new column, enter the following formula:

=VLOOKUP(A2, B:B, 2, FALSE)

This formula will look up the value in cell A2 in column A and return the corresponding value from column B. The "FALSE" parameter indicates that you want to use an exact match.

Step 3: Copy the formula down to the rest of the cells in the column. This will find the email address for each customer.

Function 3: MATCH Function

The MATCH function is used to find the position of a value in a range of cells. You can use this function to compare two columns by finding the position of each value in one column in the other column.

Step 1: Enter your data into two columns in your Google Sheet. For example, let's say you have a list of products and their corresponding prices in columns A and B.

Step 2: In a new column, enter the following formula:

=MATCH(A2, B:B, 0)

This formula will find the position of the value in cell A2 in column B. The "0" parameter indicates that you want to use an exact match.

Step 3: Copy the formula down to the rest of the cells in the column. This will find the position of each product in the price list.

Examples

Here are some examples of how to use these functions to compare two columns in Google Sheets:

• Use the COUNTIF function to count the number of customers who have made a purchase of more than \$100.

• Use the VLOOKUP function to find the email address of a customer based on their name.

• Use the MATCH function to find the position of the product with the highest price.

## Part 2: How to Compare Two Columns in Google Sheets - Other Methods

Here is a step-by-step tutorial on how to compare two columns in Google Sheets using other methods:

Google Sheets has several add-ons that can be used to compare two columns. One such add-on is Ablebits Compare Sheets. This add-on can be used to compare two columns for exact matches, duplicate values, and unique values.

Step 1: Install the Ablebits Compare Sheets add-on.

• Search for Ablebits Compare Sheets and click Install.

• Click Open.

Step 2: Open the Google Sheet that contains the two columns you want to compare.

Step 3: Click Extensions > Ablebits Compare Sheets > Compare columns.

Step 4: Select the two columns you want to compare.

Step 5: Select the type of comparison you want to perform.

• Exact matches: This will find all of the rows in which the values in the two columns are exactly the same.

• Duplicate values: This will find all of the rows in which the values in the two columns are the same, regardless of the order of the columns.

• Unique values: This will find all of the rows in which the values in one column are unique, meaning that they do not appear in the other column.

Step 6: Click Compare.

Step 7: The results of the comparison will be displayed in a new sheet.

Method 2: Using Equal operator

You can also use the equal operator (==) to compare two columns in Google Sheets. This method is only useful for comparing two columns for exact matches.

Step 1: Enter the following formula in a new column:

=A2=B2

This formula will compare the value in cell A2 to the value in cell B2 and return TRUE if the values are the same, and FALSE if the values are different.

Step 2: Copy the formula down to the rest of the cells in the column. This will compare the values in the two columns for each row.

Here is a brief overview of the differences between the 2 methods:

 Feature Ablebits Compare Sheets Add-on Equal operator Ease of use More complex to use, requires installation of an add-on Simpler to use, only requires knowledge of the equal operator Functionality Can compare two columns for exact matches, duplicate values, and unique values Can only compare two columns for exact matches Flexibility Can compare two columns in different sheets Can only compare two columns in the same sheet Output Displays the results of the comparison in a new sheet Displays the results of the comparison in the same sheet

Overall, the Ablebits Compare Sheets Add-on is a more powerful and flexible tool for comparing two columns in Google Sheets. However, the equal operator is a simpler and more straightforward method for comparing two columns for exact matches.

Nested formulas and COUNTIF functions provide flexible comparison options, while add-ons offer user-friendly interfaces and extended functionalities. The choice of method depends on the complexity and flexibility required for the specific comparison task.
