Data wrangling courses can help you learn data cleaning, transformation techniques, and data integration methods. You can build skills in handling missing values, reshaping datasets, and merging data from multiple sources. Many courses introduce tools such as Python libraries like Pandas and NumPy, as well as SQL for database management, showing how these skills streamline data preparation for analysis and visualization.
