              After reviewing the dataset, you observe several issues that must be corrected— duplicates, inconsistent formats,
              spelling mistakes, missing values, and so on. Let’s learn how to handle each of these, step by step.


              Removing Duplicates
              The first step in data cleaning is to identify and remove duplicate entries so that no record is counted more than once.
              This ensures accuracy and consistency in your dataset. Follow these steps to remove duplicate entries in Excel:

               Step 1   Enter the data in the spreadsheet.
               Step 2   Select the ID column by clicking on the column header, A.
               Step 3   Click on the Home tab in the Ribbon.
               Step 4   Click on the Conditional Formatting   Highlight Cell Rules   Duplicate Values option in the Styles group.







































                      The Duplicate Values window opens.
