Deduplicating rows

You can use the Remove duplicate rows function to easily delete all the rows that are exact duplicates and keep only one in your dataset.

Duplicated information can be introduced in spreadsheets because of human error, like a bad copy and paste for example, as well as automated operations. In this example, you received a dataset containing customer information, where all the rows are systematically duplicated.
