Sorting the Excel table

You need an Excel table specialist. There is a base in Excel - more than 13 thousand names. One name is one cell, all cells are in one column. The information is packed in different formats. Main: Ivanov Ivanovich, Ivan Ivanov, Ivanov, Ivan. But there are cells where the information is entered in a different order. There are also incorrectly filled cells (instead of a name - a phrase).
Task: Remove names and place them in a separate column (without changing the order in the list).
