Compiling a List of Students in a Course

Keval has a table of over 5,000 students distributed across 22 courses of study. Against each student's name in each row of this table is indicated the course in which the student is registered. Keval would like, on a different worksheet, to put a course name in cell A1 and then have Excel display, beginning in row 3, all the students in that course, as pulled from the list. He wonders if there is a way to do this with a formula.

The best solution to this problem is going to be dependent, in large part, on how your source data is organized. If you only have two columns (student name and course name), then it is possible that you don't even need to use a second worksheet. Instead, you can get by using Excel's filtering capabilities. Just filter on the contents of the column that contains the course name, and you can easily limit what is displayed to only those students in the course.

If you must have the information appear on the second worksheet, it may be best to use an array formula to extract the students. Put the desired course in cell A1 and then the following formula in cell A3:

=IF(COUNTIF(Sheet1!$B$1:$B$5000,$A$1)<ROW()-2,"",
INDEX(Sheet1!$A$1:$A$5000,SMALL(IF(Sheet1!$B$1:$B$5000=$A$1,
ROW(Sheet1!$B$1:$B$5000)),ROW()-2)))

Remember—this is a single formula and you need to enter it in the cell by pressing Ctrl+Shift+Enter. Copy the formula downward into enough cells that it should accommodate your largest class. The formula also assumes that the source data in in rows 1 through 5000; if this is not the case, you'll want to modify the formula to reflect the appropriate range.

Another approach is to create a PivotTable based upon the student/course list. All you need to do is make sure that both the course name and the student name fields are in the "row" area of the PivotTable. Put the course name field first and the student name field second, and you'll end up with a list of all courses with the students under each course name.

If your source data has additional information associated with it (such as grades, addresses, book assignments, etc.), then you may want to consider working with an actual database program, such as Access. You'll be able to manipulate and extract data using tools that are superior to those in Excel.
