To Remove Duplicate Rows in a CSV File
Step 1: Open your file with a dedicated CSV Editor - Rons Data Edit
First things first, make sure you use the correct application to edit your CSV files; you can download Rons Data Edit, for free, right here: Download.
Your CSV file can be opened using the 'Open Document' File menu, or 'Open Document' link on the Start Page of the application.
Step 2: Delete Duplicate Rows.
To delete duplicate rows in the CSV File, look for the 'Rows' tab in the ribbon bar at the top of the window and click on it. Click on the "Delete Duplicate" button. When done, a pop up message displays the number of rows deleted.
Step 3: Save the File
When satisfied with the changes, make sure to save the document by clicking on the 'Save' button at the top left corner of the main window or by clicking the 'Save' button on the 'Home' tab of the ribbon bar.
