 Removing duplicates in excel:

  • The Remove Duplicates function is used to remove duplicate entries. Duplicate entries are values that two or more are the same. This can be both numbers and text inputs. A1 and A2 are duplicates since they have the same values. Select the range where you want to remove duplicate values.

1. Select Your Data:

  • Highlight the range of cells where you want to remove duplicates. You can select a column or a table (multiple columns and rows) based on your needs.

2. Open the "Data" Tab:

  • Go to the Data tab in the Excel ribbon at the top of the window.



3. Click "Remove Duplicates":

  • In the "Data Tools" group, click the "Remove Duplicates" button.




4. Choose Columns to Check for Duplicates:

  • A pop-up window will appear where you can choose which columns to check for duplicates. By default, Excel will check all columns that are part of your selected range.
  • If you want to remove duplicates based on one specific column, uncheck the others.
  • If you want to remove duplicates based on all columns, leave them all checked.

5. Click "OK":

  • After selecting your columns, click OK.

6. Review the Results:

  • A message will appear telling you how many duplicates were removed and how many unique values remain in the dataset.
