How to Count Duplicates in Excel: A Step-by-Step Guide for Beginners

How to Count Duplicates in Excel

Counting duplicates in Excel is pretty easy once you know the steps. You just need to know a couple of formulas and where to find the right functions. We’ll walk you through it step by step. By the end, you’ll be able to quickly count how often each value appears in your dataset.

Step-by-Step Tutorial: How to Count Duplicates in Excel

This tutorial aims to help you accurately count duplicate entries in your Excel spreadsheet, enabling better data analysis and management.

Step 1: Open Your Excel Workbook

Open the Excel workbook that contains the data you want to analyze.

Make sure you have your dataset ready. You can use any version of Excel for this, whether it’s an older one or a newer one.

Step 2: Select the Data Range

Select the range of cells that you want to check for duplicates.

Click and drag your mouse over the cells. Make sure you capture all the rows and columns where your data are stored.

Step 3: Use the COUNTIF Function

In an empty cell, type in the formula: =COUNTIF(range, criteria).

For example, if your data are in column A, your formula might look like this: =COUNTIF(A:A, A2). This formula will count the number of times the value in cell A2 appears in column A.

Step 4: Drag the Formula Down

Click on the small square at the corner of the cell with the formula and drag it down to apply it to other cells.

This action will copy the formula, so you can see the count of each value in your dataset.

Step 5: Filter for Duplicate Counts

You can now filter your data to show only duplicate counts by using Excel’s filter feature.

Click on the filter icon, select ‘Number Filters,’ and then choose ‘Greater than’. Enter "1" to show only values that appear more than once.

After you complete these steps, Excel will display the number of times each value appears in your dataset. It’s a simple yet powerful way to manage and analyze your data.
