    Comparing lists of values (SIM #'s)

    Hello Excel Forum!

    So I am no Excel expert, I am a novice at best. My job has asked me to compare a list of device IDs (+30,000) to a few other list of IDs (a few thousand or a few hundred). I need to find what device IDs on the smaller lists are also on the large master list - if at all.

    Is there a quick and 'easy' way to do this in excel? I do not want to go line by line - copy, pasting and finding until I have completed the list...that would take weeks!

    Please let me know if you need more information or have any questions.

    Thank you.

    Device List Example.xlsx

    The attachment is an example of the Device # and list. It is only ~100 items but each list will look like this. The master is 30,000 devices and the others are from 100-15,000.

    Thanks.

    Yes, that is exactly what I need. Would it be possible to do this but also have list 3, 4, 5, 6, etc.?

    How do you go about comparing the lists? I apologize if this is a simple task - I am so rusty!

    Re: Comparing lists of values (SIM #'s)

    Yes, but...

    It uses an array formula that may be very slow to work through your lists. They're a little different from ordinary formulas in that they MUST be confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER.

    You will know the array is active when you see curly braces { } appear around the outside of your formula. If you do not CTRL+SHIFT+ENTER you will get an error message or an incorrect answer. Press F2 on that cell and try again.

    Don't type the curly braces yourself - it won't work...

    can you use the first method, filter on the column containing the duplicates and paste them somewhere else?

    Re: Comparing lists of values (SIM #'s)

    Sorry, I forgot to mention that I created two Named ranges to simplify the look of the formulae. If yoou go with tis approach, we can madke those Named Ranges dynamic, so that they'll automatically adjust to suit your real data.
