Method 2: Using the “FILTER” function
This method uses the “FILTER” function to remove duplicates. Here’s how to do it:
Assuming your data is in the range A1:B10, you can use the following formula:
| =FILTER(A1:B10, COUNTIF(A1:A10, A1:A10) = 1) |
This formula will return a new range with only the unique entries.
Method 3: Using the “QUERY” function
This method uses the “QUERY” function to remove duplicates. Here’s how to do it:
Assuming your data is in the range A1:B10, you can use the following formula:
| =QUERY(A1:B10, “SELECT * WHERE A NOT IN (SELECT A FROM A1:B10 GROUP BY A HAVING COUNT(A) > 1)”) |
This formula will return a new range with only the unique entries.
Method 4: Using an add-on
If you need to remove duplicates frequently, you can use an add-on like “Remove Duplicates” or “Duplicate Remover”. These add-ons provide a simple and easy-to-use interface to remove duplicates. (See Also: How To Delete Rows In Google Sheets Mobile)
