What is the function of a split label column in data import?

The function of a split label column in data import is primarily to categorize data into separate rows. This feature is particularly useful when dealing with datasets that require differentiation for accurate processing. By defining a split label column, users can ensure that the data is organized and displayed correctly, aligning entries with their respective categories. This allows for better analysis and reporting, as each entry can be distinctly identified based on the labels provided in the column.

While the other options touch on data handling, they do not accurately describe the specific purpose of the split label column. Concatenating data entries or combining multiple sources does not align with the splitting functionality, and data deletion prevention relates to data integrity rather than categorization during imports.
