Common Mistakes to Avoid
- Don’t Use the "Duplicate" Function on Entire Columns: The "Duplicate" function is designed to identify and highlight duplicate rows, not entire columns. If you use it on entire columns, you may end up with incorrect results.
- Don’t Use the "Find Duplicates" Feature on Large Data Sets: The "Find Duplicates" feature can be slow and inefficient on large data sets. If you have a large data set, it’s best to use the "Remove Duplicates" feature instead.
