Step 1: Open Google Sheets

1. Go to your Google Drive and open the desired spreadsheet, or create a new one.

Step 2: Select the Data Range

Common Mistakes to Avoid

While the process is simple, here are some common mistakes users make when highlighting duplicates in Google Sheets:

1. Incorrect Range Selection: Always ensure that you've selected the correct range of cells. If you miss even one cell, the duplicates might not highlight.
2. Wrong Formula: Double-check the formula you entered. A small error can lead to the formatting not working as expected.
3. Not Adjusting for Multiple Columns: If you're checking for duplicates across multiple columns, be sure to adjust your formula accordingly.
4. Ignoring Format Settings: Sometimes, users might overlook selecting the right format for visibility. Always choose a color that stands out against the background.

Troubleshooting Issues

Should you encounter issues while trying to highlight duplicates, here are a few troubleshooting tips:

• Double-check your formula: Ensure you've entered the formula correctly and that it corresponds to the selected range.
• Refresh the Page: Sometimes, refreshing your Google Sheets can fix minor glitches.
• Check for Spaces: Often, invisible spaces can make values appear unique. Use the TRIM function to clean up your data if necessary.
• Re-evaluate the Format: If your duplicates aren’t showing, ensure that the formatting style has been selected and applied correctly.

Examples of Use Cases

To better illustrate the practical applications of highlighting duplicates, let’s look at a couple of examples:

Example 1: Contact Lists

Imagine you have a list of contacts and you want to ensure there are no duplicate phone numbers. By applying the conditional formatting technique described above, you can easily spot and address any duplicates, thereby maintaining an accurate contact list.

Example 2: Product Inventory

Suppose you're managing an inventory list for a retail store. Highlighting duplicate product IDs will help ensure that you don't accidentally order the same product multiple times, keeping your inventory streamlined and efficient.
