Data cleaning in Excel is the process of identifying and correcting errors, inconsistencies, and inaccuracies in datasets to ensure the data is accurate, complete, and ready for analysis. It is a critical step in data management, especially when working with large datasets gathered from various sources.
Common issues that require cleaning include duplicate entries, blank cells, incorrect formats, misspelled text, and inconsistent data (like multiple spellings of the same word). Excel offers a variety of built-in tools and functions to address these issues efficiently.
