comparing names in a list
 

I have two very long lists of student names in one worksheet. The names in
A1:A500 is the master list. The student names in B1:B200 have successfully
passed their exam. I would like to know which student names are NOT in the
second list by comparing it to the master .

comparing names in a list
 

One way ..

Put in C1:
=IF(A1="","",IF(ISNUMBER(MATCH(A1,B:B,0)),"",ROW() ))

Put in D1:
=IF(ISERROR(SMALL(C:C,ROW())),"",
INDEX(A:A,MATCH(SMALL(C:C,ROW()),C:C,0)))

Select C1:D1, fill down to A500

Col D will return the required results,
all neatly bunched at the top
(items in col A not in col B)

oops, typo in line:
Select C1:D1, fill down to A500

should read as:
Select C1:D1, fill down to D500
(fill down to the last data row in col A)

I would insert a helper column to the left of column A and enter
=COUNTIF(B1,C$1:C$200)

Then copy down to row 500. This will return 0 for anyone who does not
appear in column B.

You could then use a filter to identify the 0's in column A. You'll
probably need column headers to use the autofilter. You could then
copy/paste your filtered list to another sheet.

Max...I cut and pasted the formulas and corrected for the typo and the
results are bundled nicely like you promised all at the top of the column D
...but the results are inaccurate . I get names in Column D from the master
list A1:A500 but their names are not in column B because they did not pass
their exam.

I am wondering if there is an error in the formula but I dont understand how
you figured it out. please help :)
