Comparing two large excel sheets
I have two large excel files. I have to to combine the two files to see who is missing from the first file to the second file. The files are mostly the same besides a handful of differences. I can...
Hey,
there are multiple ways to compare two files. But it would require some additional information two find a possible solution.
If for example you have a unique identifier (e.g. an ID), you could use a =UNIQUE() function on the column and use =COUNTIF() to count the occurrences for each ID in a separate file or worksheet for both files and compare the results. Based on this comparison you at least would know which rows are missing.
- So they all do have ID numbers. It’s an Active roster sheet. So I get the first sheet and shows me all active, when I get the next sheet, shows me all active again but will now have people missing that have been terminated. So I need to compare the two to find who has disappeared from the original sheet compared to the second sheet
Gluksker Hey again,
in that case you can use a lookup function, e.g.:
ID - Sheet 1
Check ID - Sheet 2 1 =XLOOKUP(A2;C:C;C:C;"Missing") 2 2 2 3 3 3 5 4 4 4 5 5 6 6 6 7 7 7 8 Missing 9 Missing 10 Missing But depending on your machine, this can take some time, or could lead the file to crash.
