In the file menu there is an option to export the schedule to a tab or comma delimited file format. When you select this menu option a dialog box, similar to the Schedule Sorted by Course dialog, will appear that allows you to select to export tentative classes, the style of the professor name, and to use commas or tabs to delimit the columns. Either of these formats can then be easily read into a spreadsheet such as Microsoft Excel or LibreOffice Calc.
The first column will be the department code, second the course name, third the section number, fourth the class title (with subtitle if included), fifth the professor's name (note if you use comma delimited and the formal name then the last name will be split from the first and middle names), from there on out every four columns will be a block of timeslots. The timeslots start with the days of the week, then the beginning time, then the ending time, and finally the room. Note that all times here are on a 24 hour clock. Also note that for tentative classes, there will be a (T) after the section number.
