All four parts of the employee addresses (street address, city, state, and zip code) have been entered into a single column. While this may work for some purposes, it isn't ideal. With the data in one cell, it cannot be sorted, filtered, or otherwise analyzed by any of the individual elements. For example, you could not use this data to see how many employees live in Indiana or to create mailing labels sorted by zip code.
Google Sheets has an easy way to separate data into multiple columns.
