In data preprocessing, it's a common practice to perform tasks like spell correction and punctuation cleanup before one-hot encoding features. These initial data cleaning steps are essential because they ensure the quality and consistency of the data, making it suitable for subsequent analytical processes such as one-hot encoding, which is crucial for transforming categorical variables into a numerical format that machine learning algorithms can work with effectively.
