Transforming text data
You notice product names in your grocery inventory database have inconsistent formats. Some have parentheses like "Apple (Organic)", extra spaces, and mixed capitalization. This makes it hard to match and analyze products accurately. Standardize these names by removing parenthetical descriptions, cleaning up surrounding spaces, and converting to lowercase.
