Fortunately, Google Sheets offers a simple and effective way to remove duplicates from your spreadsheet. In this blog post, we will learn how to remove duplicates from Google Sheets in a few easy steps.

1. Identify the Duplicate Cells
The first step is to identify the cells that contain duplicate data. You can do this by using the conditional formatting feature in Google Sheets.

a) Select the cells that you want to check for duplicates.
b) Go to Format > Conditional Formatting from the menu bar.
c) In the sidebar, select “Custom formula is” from the drop-down menu.
d) In the formula field, enter “=countif(A:A,A1)>1” (replace A:A with the column or range where your data is located).
e) Click on the formatting style you want to use for the duplicate cells (ex. red fill color).
f) Click on “Done”.

This will highlight all the duplicate cells in the selected range, making it easier to spot and remove them.

2. Remove Duplicates
After identifying the duplicate cells, you can remove them using the built-in remove duplicates feature in Google Sheets.

a) Select the range of cells that contains duplicate data.
b) Go to Data > Remove Duplicates from the menu bar.
c) A pop-up window will appear, click on “Continue”.
d) In the next window, check the box next to “Data has header row” if your data has headers in the first row.
e) Click on “Remove Duplicates”.

This will remove all the duplicate cells and keep only the unique values in the selected range.

3. Use the UNIQUE Function
Another method to remove duplicates in Google Sheets is by using the UNIQUE function.

a) Create a new empty column next to your data.
b) In the first cell of the new column, enter the formula “=unique(A:A)” (replace A:A with the column or range where your data is located).
c) Press Enter, and all the unique values will be extracted in the new column.
d) Select the entire column of unique values, then right-click and choose “Copy”.
e) Paste the values in a new column or replace the original column with the values.

This method will keep only the unique values and remove all duplicates in your data.

You can also use the sort function to remove duplicates in Google Sheets.

a) Select the range of cells that contains duplicate data.
b) Go to Data > Sort Range from the menu bar.
c) In the pop-up window, select the column that you want to sort in the “Sort by” drop-down menu.
d) Check the box next to “Data has header row” if your data has headers in the first row.
e) Click on “Sort”.
f) In the sorted column, scroll down to the point where the values start repeating.
g) Delete the duplicate rows below the unique values by selecting them and pressing the “Delete” button on your keyboard.

var data = sheet.getDataRange().getValues();
var newData = new Array();
for(i in data){
var row = data[i];
var duplicate = false;
for(j in newData){
if(row.join() == newData[j].join()){
duplicate = true;
