How to Check for Duplicates in Google Sheets

Conditional Formatting
Conditional Formatting in Google Sheets is a powerful tool that simplifies the identification of duplicates in your data. Follow these steps to highlight duplicates: select your desired cell range, click on Format, choose Conditional Formatting, and set the rules with a custom formula like ‘=COUNTIF(A:A,A1)>1.’ Tailor ‘A:A’ and ‘A1’ to match your selected range and first cell. While it doesn’t eliminate duplicates, it offers a swift identification process, allowing you to decide whether to manually delete them or employ another removal method.

Removing Duplicates Effortlessly
Google Sheets provides a built-in feature for removing duplicates swiftly. Just select your cell range, click on Data, and choose ‘Remove duplicates.’ A dialog box will prompt you to confirm your selection and specify removal criteria. This method, although quick and easy, retains only the first occurrence of a value, removing the rest. If you seek more control over which duplicates to retain or discard, consider using a formula or script.

COUNTIF Formula for Precision
Empower yourself with the COUNTIF formula to precisely identify duplicates. Input ‘=COUNTIF(A:A,A1)’ in a cell adjacent to your selected range, adjusting ‘A:A’ and ‘A1’ accordingly. This formula reveals the count of each value, enabling a more controlled approach to duplicates. Keep in mind that it doesn’t remove the duplicates; manual removal is required.

UNIQUE Formula for Simplified Removal
For a straightforward duplicate removal process, leverage the UNIQUE formula. In a cell, input ‘=UNIQUE(A:A)’ with ‘A:A’ reflecting your chosen range. This formula generates a list of unique values, effectively eliminating duplicates. However, it lacks detailed control or a summary of the removed duplicates.
