Duplicates in Excel refer to identical or nearly identical records within a dataset. They can occur in single columns or across multiple columns, depending on how the data is structured. For instance, if you have a customer list, a duplicate might be two rows with the same name and email address. However, even minor discrepancies in data—like a trailing space or a different case—might cause Excel to treat records as unique.
Duplicates can occur due to various reasons such as manual data entry, importing data from external sources, or merging datasets. These repetitions can lead to inaccurate results in analyses, reporting, and decision-making processes.
Whether you're working on sales reports, customer lists, or financial records, duplicate entries can wreak havoc on your results. They not only inflate your data but also compromise its integrity. Thankfully, Excel offers a range of built-in tools and techniques to identify, highlight, and remove duplicates effectively, saving you time and reducing errors.
