Excel How to Compare Columns: A Step-by-Step Guide

Comparing columns in Excel is a handy skill to have, especially when you’re dealing with large datasets. It can help you quickly identify differences or similarities between two sets of data. Whether you’re a seasoned Excel pro or a beginner, this task is simple to accomplish once you know the steps.

Step by Step Tutorial: Excel How to Compare Columns

Before we dive into the steps, let’s understand what we’re aiming to achieve. Comparing columns in Excel allows you to see if there are any discrepancies or matches between two sets of data. This can be particularly useful for tasks such as reconciling accounts, finding duplicates, or ensuring consistency across reports.

Step 1: Open your Excel workbook

Open the Excel workbook containing the columns you wish to compare.

This step is self-explanatory. You need to have your Excel application running and the specific workbook open to carry out any tasks.

Step 2: Select the first column you want to compare

Click on the header of the first column you wish to compare to highlight the entire column.

Remember, you can also select a specific range within the column if you do not wish to compare the entire column. Just click and drag to select the range you want.

Step 3: Use the ‘Conditional Formatting’ feature

With the column selected, go to the ‘Home’ tab, click on ‘Conditional Formatting’, and then select ‘Highlight Cells Rules’ followed by ‘Duplicate Values’.

Conditional Formatting is a powerful tool in Excel that allows you to format cells based on certain criteria, such as whether the cell contents are duplicates or unique.

Step 4: Repeat steps 2 and 3 for the second column

Now, repeat the process for the second column you want to compare.

Make sure you apply the same conditional formatting rule to this column as you did to the first column.

Step 5: Review the results

Excel will highlight the cells that are duplicates or unique, depending on the option you selected in the Conditional Formatting.

Now you can easily see the differences or similarities between the two columns. If you need to, you can sort or filter the columns to further analyze the highlighted data.

After completing these steps, you’ll have a visually clear representation of how the data in the two columns compares. This can be incredibly useful for a variety of tasks and will save you the time and effort of manually searching through the data.

Tips: Excel How to Compare Columns

• Make sure the data you are comparing is in the same format. For example, ensure that dates are formatted as dates in both columns.
• If you’re comparing numbers, consider using the ‘Exact’ function to identify differences that might be due to rounding or decimal places.
• Use ‘Conditional Formatting’ to highlight not just duplicates, but also unique values, to see which values appear in one column but not the other.
• For a more advanced comparison, consider using Excel formulas such as VLOOKUP or MATCH.
• Remember to clear the conditional formatting once you’re done comparing the columns to avoid confusion in the future.
