Working with your data on Google Sheets has become reliable especially when you need to save your spreadsheets on a cloud. It became an alternative to Excel yet, there are some limitations that you can encounter along the way.
For large data on spreadsheets, it is not impossible to run in problems like duplicating entries. Working on increasing data will also increase the likelihood of duplicates, which increase risk especially when dealing with important documents. It can lead to miscalculations and false data entry.
However, there are ways on how you can find duplicates in Google Sheets even with a wide spreadsheet on hand. Check out the methods below:
Highlight Duplicates With Color Highlighting

- Open your Google Sheets and select the spreadsheet you want to edit.
- You can select one column or multiple columns. Click on the columns you want to check.
- Next, go to the toolbar and click Format to open a drop-down menu.
- Select Conditional Formatting.
- On the sidebar, look for Format cell if… Then click on the drop down menu.
- Choose Custom formula is.
- Type =COUNTIF(A:A,A1)>1 in the box to highlight all the cells in the A column from the first cell to the last. If you want to highlight a different column, simple change A:A and A1 to the column you want to highlight. For instance, =COUNTIF(D:D,D1)>1 will highlight column D. Another note to consider is the first cell you want to begin with. If you want to begin with A6 in the column, simply change A1 to A6. For instance,=COUNTIF(A:A,A6)>1
