When working with large datasets in Google Sheets, it’s common to encounter duplicate values that can clutter your data and make it difficult to analyze. Duplicates can occur due to various reasons such as data entry errors, incomplete data, or data merging. Hiding duplicates in Google Sheets can help you to focus on the unique values, simplify your data, and improve the overall performance of your spreadsheet. In this article, we will explore the various methods to hide duplicates in Google Sheets, including using built-in functions, formulas, and add-ons.
Method 1: Using the UNIQUE Function
The UNIQUE function is a built-in function in Google Sheets that can be used to remove duplicates from a range of cells. This function is available in Google Sheets version 2017 and later. To use the UNIQUE function, follow these steps:
1. Select the cell range that contains the data you want to remove duplicates from.
2. Type “=UNIQUE(” and select the cell range.
3. Close the parentheses and press Enter.
The UNIQUE function will return a list of unique values from the selected range. You can then use this list to hide duplicates in your original data. To do this, follow these steps:
1. Select the cell range that contains the original data.
2. Go to the “Data” menu and select “Filter views”.
3. In the “Filter views” dialog box, select the column that contains the data you want to remove duplicates from.
4. Click on the “Filter” button and select “Custom formula is” from the dropdown menu.
5. In the formula bar, type “=NOT(LOOKUP(A2, UNIQUE(A:A))=A2)” and press Enter.
This formula will hide all duplicates in the selected column. The LOOKUP function is used to check if the value in cell A2 is present in the list of unique values returned by the UNIQUE function. If the value is not present, the formula returns TRUE, which means the value is unique and should not be hidden.
Method 2: Using the FILTER Function
The FILTER function is another built-in function in Google Sheets that can be used to remove duplicates from a range of cells. This function is available in Google Sheets version 2017 and later. To use the FILTER function, follow these steps:
1. Select the cell range that contains the data you want to remove duplicates from.
2. Type “=FILTER(A:A, COUNTIF(A:A, A2)=1)” and press Enter.
The FILTER function will return a list of unique values from the selected range. You can then use this list to hide duplicates in your original data. To do this, follow these steps:
1. Select the cell range that contains the original data. (See Also: What If Analysis On Google Sheets? Boosting Decision Making)
2. Go to the “Data” menu and select “Filter views”.
3. In the “Filter views” dialog box, select the column that contains the data you want to remove duplicates from.
4. Click on the “Filter” button and select “Custom formula is” from the dropdown menu.
5. In the formula bar, type “=FILTER(A:A, COUNTIF(A:A, A2)=1)” and press Enter.
This formula will hide all duplicates in the selected column. The COUNTIF function is used to count the number of times the value in cell A2 appears in the selected range. If the value appears only once, the formula returns TRUE, which means the value is unique and should not be hidden.
Method 3: Using Add-ons
There are several add-ons available in the Google Sheets store that can be used to remove duplicates from a range of cells. One popular add-on is the “Remove Duplicates” add-on. To use this add-on, follow these steps:
1. Go to the Google Sheets store and search for “Remove Duplicates” add-on.
2. Click on the “Install” button to install the add-on.
3. Once the add-on is installed, go to the “Tools” menu and select “Remove Duplicates”.
4. In the “Remove Duplicates” dialog box, select the range of cells that contains the data you want to remove duplicates from.
5. Click on the “Remove” button to remove all duplicates from the selected range.
This add-on will remove all duplicates from the selected range and return a list of unique values. You can then use this list to hide duplicates in your original data. To do this, follow these steps:
1. Select the cell range that contains the original data.
2. Go to the “Data” menu and select “Filter views”.
3. In the “Filter views” dialog box, select the column that contains the data you want to remove duplicates from.
4. Click on the “Filter” button and select “Custom formula is” from the dropdown menu.
5. In the formula bar, type “=NOT(LOOKUP(A2, UNIQUE(A:A))=A2)” and press Enter. (See Also: How to Combine Columns Google Sheets? Master The Merge)
This formula will hide all duplicates in the selected column. The LOOKUP function is used to check if the value in cell A2 is present in the list of unique values returned by the UNIQUE function. If the value is not present, the formula returns TRUE, which means the value is unique and should not be hidden.
Method 4: Using Conditional Formatting
Conditional formatting is a powerful feature in Google Sheets that can be used to highlight duplicates in a range of cells. To use conditional formatting to hide duplicates, follow these steps:
1. Select the cell range 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 column that contains the data you want to remove duplicates from.
4. Click on the “Format” button and select “Custom formula is” from the dropdown menu.
5. In the formula bar, type “=COUNTIF(A:A, A2)>1” and press Enter.
This formula will highlight all duplicates in the selected column. The COUNTIF function is used to count the number of times the value in cell A2 appears in the selected range. If the value appears more than once, the formula returns TRUE, which means the value is a duplicate and should be highlighted.
Method 5: Using a Script
Google Sheets also provides a scripting feature that can be used to remove duplicates from a range of cells. To use a script to remove duplicates, follow these steps:
1. Go to the “Tools” menu and select “Script editor”.
2. In the script editor, delete any existing code and paste the following code:
function removeDuplicates() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange("A:A");
var data = range.getValues();
var uniqueData = [];
for (var i = 0; i < data.length; i++) {
var row = data[i];
var exists = false;
for (var j = 0; j < uniqueData.length; j++) {
if (row[0] == uniqueData[j][0]) {
exists = true;
break;
}
}
if (!exists) {
uniqueData.push(row);
}
}
var uniqueRange = sheet.getRange(1, 1, uniqueData.length, 1);
uniqueRange.setValues(uniqueData);
}
3. Save the script by clicking on the “Save” button.
4. Go back to your Google Sheet and select the cell range that contains the data you want to remove duplicates from.
5. Go to the “Tools” menu and select “Run script”.
6. In the “Run script” dialog box, select the “removeDuplicates” function and click on the “Run” button.
This script will remove all duplicates from the selected range and return a list of unique values. You can then use this list to hide duplicates in your original data. To do this, follow these steps:
1. Select the cell range that contains the original data.
2. Go to the “Data” menu and select “Filter views”.
3. In the “Filter views” dialog box, select the column that contains the data you want to remove duplicates from.
4. Click on the “Filter” button and select “Custom formula is” from the dropdown menu.
5. In the formula bar, type “=NOT(LOOKUP(A2, UNIQUE(A:A))=A2)” and press Enter.
This formula will hide all duplicates in the selected column. The LOOKUP function is used to check if the value in cell A2 is present in the list of unique values returned by the UNIQUE function. If the value is not present, the formula returns TRUE, which means the value is unique and should not be hidden.
