## Comparing Two Columns in Excel to Find Differences

Comparing two columns in Excel is a very useful tool for finding differences between two sets of data. Excel offers a variety of methods for quickly and accurately finding the differences between two columns. It is important to understand the different methods available and how to use them to best meet your needs. In this article, we will discuss five methods for comparing two columns in Excel to find differences.

### 1. Using Conditional Formatting

Conditional formatting is one of the best methods for quickly comparing two columns in Excel. It allows you to highlight cells that meet a certain criteria, such as being different from the corresponding cell in another column. To use conditional formatting, select the two columns you want to compare, then click the “Home” tab. In the “Styles” section, click the “Conditional Formatting” button and select “Highlight Cells Rules”. Select “Different Values”, then click “OK”. This will highlight any cells in the two columns that have different values.
