Step 1: Select the Data
The first step in removing duplicates is to select the data that you want to check for duplicates. You can do this by clicking on the cell in the upper-left corner of the dataset and then dragging the cursor down to the bottom-right corner of the dataset. This will highlight all of the cells in the dataset.
Step 2: Find the Duplicates
Once you have the dataset selected, you can find the duplicates by going to the Data tab in the Excel toolbar and clicking on the "Remove Duplicates" button. This will bring up a dialog box that will ask you which columns you want to check for duplicates. Make sure that you select all of the columns that you want to check, and then click "OK."
Excel will then check the data for duplicates and remove them from the dataset. You can see how many duplicates were removed by looking at the message that appears at the bottom of the screen.
Step 3: Save the Data
Once you have removed the duplicates from the dataset, you'll need to save the data so that you can use it later. To do this, go to the File tab in the Excel toolbar and click "Save As." Choose a location for the file and a file name, and then click "Save."
You should now have a clean dataset that you can use for your analysis.
