How to Remove Duplicate in Google Sheets? Effortless Solution

1. Select the range of cells that contains the data you want to remove duplicates from
2. Go to the “Data” menu and select “Remove duplicates”
3. In the “Remove duplicates” dialog box, select the columns that you want to use to identify duplicates
4. Click “Remove duplicates” to remove the duplicates from the selected range

The Remove Duplicates tool uses the values in the selected columns to identify duplicates. If two or more rows have the same values in the selected columns, they will be considered duplicates and removed from the data.

Using Conditional Formatting

Conditional formatting is a powerful tool in Google Sheets that allows you to highlight cells based on specific conditions. You can use conditional formatting to identify duplicates in your data and then remove them. To use conditional formatting to remove duplicates, follow these steps:

1. Select the range of cells that contains the data you want to remove duplicates from
2. Go to the “Format” menu and select “Conditional formatting”
3. In the “Conditional formatting” dialog box, select the format you want to apply to the duplicates (e.g. red fill)
4. In the “Format cells if” section, select “Custom formula is” and enter the following formula: `=COUNTIF(A:A, A2)>1` (assuming the data is in column A)
5. Click “Done” to apply the conditional formatting

The conditional formatting formula counts the number of times each value appears in the range A:A. If a value appears more than once, it will be highlighted in red. You can then use the “Delete” key to remove the highlighted duplicates.

Using ArrayFormula

ArrayFormula is a powerful formula in Google Sheets that allows you to perform calculations on arrays of cells. You can use ArrayFormula to remove duplicates from a range of cells. To use ArrayFormula to remove duplicates, follow these steps:

1. Select the range of cells that contains the data you want to remove duplicates from
2. Enter the following formula in a new column: `=ArrayFormula(UNIQUE(A:A))` (assuming the data is in column A)
3. The formula will return a list of unique values in the range A:A
4. You can then copy and paste the unique values into a new range of cells

The ArrayFormula formula uses the UNIQUE function to remove duplicates from the range A:A. The UNIQUE function returns a list of unique values in the range, which can then be copied and pasted into a new range of cells.

Best Practices for Removing Duplicates in Google Sheets

When removing duplicates in Google Sheets, it’s essential to follow some best practices to ensure that you remove the correct duplicates and avoid errors. Here are some best practices to keep in mind: (See Also: How to Look up Duplicates in Google Sheets? Find Them Fast)

Use the Correct Columns

When using the Remove Duplicates tool or conditional formatting, make sure to select the correct columns to identify duplicates. If you select the wrong columns, you may remove important data or leave duplicates in your data.

Use the Correct Formula

When using ArrayFormula or other formulas to remove duplicates, make sure to use the correct formula and syntax. A small mistake in the formula can result in incorrect results or errors.

Check Your Data

After removing duplicates, it’s essential to check your data to ensure that you removed the correct duplicates and didn’t remove important data. You can use the “Find and replace” feature or the “Conditional formatting” tool to check for duplicates.
