Help Ordering Cells By Time

Good morning everyone

I work for an animal-related charity. We have a long, complicated roster developed in Excel that can be difficult to manage.

Volunteer shifts are divided by days (7 columns) and extend to over 100 rows. I need to be able to order the rows by start times, which are given in 24-hour format. However, the cells each contain a big, undifferentiated block of data indicating the volunteer's individual number (eg SP123), their respective start time (eg 14:30) and their job location and type for that day (eg 8219).

How do I create a formula that will 'see' the start time in each cell and allow me to order those start times within individual columns indicating days? I want to be able to instantly see the earliest Monday shift, followed in the next row by the second-earliest, then the third-earliest, and so on. The last row should show the latest shift of that particular day.

Please find attached a sample of the roster.

Many thanks, Kent
