Microsoft Excel 2003 (full product)

I have hundreds of matching pairs (552 to be exact) of data under Col. A & B. If I were to enter or paste some data into Col. C (into row 1 and down) similar to the data under Col. B. How can I have it show the match number under Col. A into Col. D? See sample below: A B C D

Hi, The function to do this is VLOOKUP()

Unfortunately VLOOKUP() wont return values from columns to the left of the value being looked up.So add a new column C

in C1 enter = A1

and drag the formula down.

Column B will have the values to be searched and column C will have the matched data to be returned.Your values to be searched are now in column D

In cell E1 enter this:

=VLOOKUP(D1,$B$1:$C$22,2,FALSE)

Drag the formula down alongside all the values to be matched in column D.

The $ signs keep the search range fixed.

After dragging the formula down it should look like this in Cell E9 =VLOOKUP(D9,$B$1:$C$22,2,FALSE)The 2 in the formula means that the result is returned from the second column of the table.

FALSE is required to ensure an exact match.

More information can be found about VLOOKUP() in Excel help files.Regards

Hi Humar, I tried what you've suggested and it worked very well. The only problem (question) I still have which can't be explained is when I paste the data (which were copied from somewhere else) into the cells for checking, it worked perfectly. But when I type in similar (or even exact) data, it won't find a match. I can't figure out the difference or format of the data between the copied ones and the entered ones. Any idea??

Hi, As these are numbers, it may be that Copy and paste is text, but when entering directly into the cells, Excel recognizes them as numbers.

Another problem can be spaces after a word - they are invisible but stop the match working.

To test for Numbers vs. Text format the cells as 'General' and if Excel recognizes the data as a number it is right aligned, but if it's text its left aligned.

You can use the LEN(A1) function to look for extra spaces - if the length is more than it should be you have extra spaces.

Hope this helps.

Regards

Hi Humar, Thanks for all your suggestions. That's exactly what the problem was. I just have to check and maybe format the data first. Thanks again.
