If you’ve ever worked with data in Google Sheets, you know how important it is to keep your information organized and clear. One of the most frustrating things that can happen is the accidental duplication of data. Luckily, there’s a simple way to highlight duplicates in your spreadsheets, making it easy to spot and correct any issues. In this guide, I’ll walk you through 5 easy steps to highlight duplicates in Google Sheets, along with helpful tips, tricks, and common pitfalls to avoid. 📝
Step 1: Open Your Google Sheets Document
Before diving into the magic of highlighting duplicates, you need to have your Google Sheets document open and ready to go. If you're starting from scratch, create a new sheet. Otherwise, pull up the spreadsheet you want to clean up.
Step 2: Select the Range
Next, you need to select the range of cells where you want to check for duplicates. This can be a specific column or a whole set of data across multiple columns. Here’s how to do it:
- Click and drag over the cells to highlight them.
- Alternatively, you can click on a single cell, then hold down
Shift
while clicking on another cell in the range to select everything in between.
Step 3: Open Conditional Formatting
Now that your range is selected, it’s time to open the conditional formatting menu. This is where the magic happens!
- Go to the menu bar and click on Format.
- From the drop-down menu, select Conditional formatting.
Step 4: Set Up the Custom Formula
In the conditional formatting sidebar, you’ll see an option that says “Format cells if…” Click the drop-down menu next to it and choose Custom formula is. Then, in the formula field, you’ll need to enter the following formula:
=COUNTIF(A:A, A1) > 1
Note: Make sure to adjust "A:A" to the appropriate range where you want to check for duplicates. If you are checking in column B, for instance, change "A:A" to "B:B". The A1
reference should always be the top cell of your selection.
Step 5: Choose Your Formatting Style
Finally, you can choose how you want duplicates to be highlighted.
- Click on the Formatting style area and select a color to fill the duplicate cells. You can also adjust the text color, boldness, and more!
- After you’ve chosen your formatting, click Done.
Voilà! You should now see your duplicates highlighted. 🎉
Helpful Tips and Tricks
- Double-Check Your Formula: Make sure you adjust the cell references based on the range you’ve selected.
- Use Color Wisely: Choose a color that stands out, but isn’t too distracting. Soft colors can be effective!
- Don’t Forget About Other Sheets: If your data spans multiple sheets, you may want to check those as well.
Common Mistakes to Avoid
- Not Adjusting the Range: Always double-check that your range is correct; otherwise, you might miss some duplicates.
- Wrong Formula: Ensure your formula references the correct column and starts from the correct row.
Troubleshooting Issues
If you find that the duplicates aren't being highlighted as expected, consider checking the following:
- Make sure there are indeed duplicate values in your selected range.
- Verify that you have correctly set up the conditional formatting rule with the right formula.
- Ensure you are looking at the correct data range, especially if your data is updated frequently.
