In the meticulous world of data management, one common challenge faced by Google Sheets users is the presence of duplicate values. These unwanted duplicates can clutter your data, impede analysis, and inflate your file size. Fortunately, Google Sheets offers a range of methods to effectively delete these pesky duplicates.
How to Delete Duplicate Values in Google Sheets
There are four primary methods to eliminate duplicate values in Google Sheets:
1. Using the Remove Duplicates Feature
This built-in function is the simplest and most straightforward way to delete duplicates. Select the column containing the duplicates, navigate to the Data menu, and choose “Remove Duplicates.” Google Sheets will then remove all duplicate rows based on the selected column.
2. Using the UNIQUE Function
The UNIQUE function extracts unique values from a range of data. To use this method, type =UNIQUE(range) in the cell where you want to list the unique values. This function will ignore any duplicates within the specified range.
3. Using Filters
Filters offer a more nuanced approach to removing duplicates. Select the column containing the duplicates, then use the filter function to highlight the unique values. Once identified, delete the rows with duplicates.
4. Using the Query Function
The QUERY function allows for more complex filtering and deduplication. Use the formula =QUERY(range, “SELECT DISTINCT(column)”) to extract unique values from a range of data.
How to Delete Duplicate Values in Google Sheets
Working with large datasets in Google Sheets, you may encounter duplicate values that can clutter your data and affect analysis. Removing these duplicates is crucial for maintaining data integrity and efficiency. Fortunately, Google Sheets offers several methods to effectively delete duplicate values.
Method 1: Using the Remove Duplicates Function

– Choose which columns to consider for uniqueness.
– Click **OK**.
The function will remove all rows with duplicate values in the selected columns.
Method 2: Using the FILTER Function
The **FILTER** function allows you to create a new sheet with unique values. To use this method:
– In a new sheet, enter the following formula:
“`
=FILTER(OriginalSheet!A:B, COUNTIF(OriginalSheet!A:A, OriginalSheet!A:A) = 1)
“`
– Replace “OriginalSheet” with the name of your original sheet and “A:B” with the range of your data.
This formula will create a new sheet with only the unique values from the specified range.
Method 3: Using the UNIQUE Function (See Also: How To Autofill Time In Google Sheets)
The **UNIQUE** function returns a list of unique values from a range. To use this method:
– Enter the following formula in a new column:
“`
=UNIQUE(OriginalSheet!A:A)
“`
– Replace “OriginalSheet” with the name of your original sheet and “A:A” with the range of your data.
This will create a new column with only the unique values from the specified range.
Key Points
– The **Remove Duplicates** function is the simplest method to delete duplicates.
– The **FILTER** function can create a new sheet with unique values.
– The **UNIQUE** function returns a list of unique values from a range.
**Recap:**
– To delete duplicate values in Google Sheets, you can use the **Remove Duplicates** function, the **FILTER** function, or the **UNIQUE** function.
– Choose the method that best suits your needs and data structure.
How To Delete Duplicate Values In Google Sheets
How do I identify duplicate values in a column?
Use the COUNTIF function to count the number of times each value appears in the column. If a value appears more than once, it is a duplicate.
How do I delete all duplicate values in a column?
Select the column and use the “Remove Duplicates” feature on the Data menu. This will remove all duplicate rows based on the values in the selected column.
How do I delete duplicate values while keeping the first occurrence?
Use the UNIQUE function to extract only the unique values from a column. This will remove all duplicate rows, leaving only the first occurrence of each value.
How do I delete duplicate values in multiple columns?
Use the COUNTIFS function to count the number of times each combination of values appears in the multiple columns. If a combination appears more than once, it is a duplicate.
How do I delete duplicate rows based on multiple criteria?
Use the FILTER function to filter the rows based on the criteria. Then, use the “Remove Duplicates” feature on the Data menu to remove all duplicate rows based on the filtered criteria.
