What is the purpose of freezing columns in a worksheet?

The primary purpose of freezing columns in a worksheet is to keep key column data visible while scrolling. This feature is especially useful in large datasets where you want to maintain sight of important information, such as headers or identifiers, as you navigate through extensive rows of data. By freezing certain columns, users can scroll horizontally through the worksheet without losing track of the context of the data they are viewing, which enhances data analysis and comprehension.

The other choices focus on outcomes that are not related to the core functionality of freezing columns. While reducing file size and preventing data entry may be relevant in other contexts, they do not apply to the freezing of columns. Similarly, although enhancing visual organization is a potential benefit of freezing, the main function is to ensure key data remains visible to aid in data management and analysis.
