A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I figured it out and wanted to let you know since you tried to help me out. The date information was stored as text because it came from a database. When I formatted the cells to date, I assumed Excel understood my intentions, but it never actually converted the cells to the date format. To fix it, I used the =VALUE() function in another column for each cell, then formatted the new column as date. Presto. Problem solved. Thank you.
