The fourth argument is empty, so the function returns an approximate match. To overcome this you need to use the SUBSTITUTE() function. When you enter a value in cell B2 (the first argument), VLOOKUP searches the cells in the range C2:E7 (2nd argument) and returns the closest approximate match from the third column in the range, column E (3rd argument). This solution won't work correctly if there are any spaces in the "Set" data. Then it is a simple matter of reconstituting the result strings. Multiplying these two grids together results in the "intersection set". Then it is a simple matter of constructing a grid for the sets where a 1 means the number exists in the set a 0 means it doesn't. The formulae work by ensuring that all the numbers in the sets have a preceding, and trailing, comma so that they can be uniquely searched for. Green Cells (entered into T2): =IF(ISERROR(FIND(","&T$1&",",","&$S2&",")),0,1)īlue Cells (entered into AL2): =IF(B2*T2,AL$1&",","")&AM2Īnd finally, the result entered into cell AK: =LEFT(AL2,LEN(AL2)-1) In excel sheet i want to compare the 2 columns. The follow formulae are entered into the top left cell of each coloured region and filled/copy-pasted/ctrl-entered into the rest of the cells. We can do this by using the VLOOKUP function. We must match whether List A contains all the List B values. Here is a screenshot of the new table with the helper columns unhidden: The steps to compare two columns in Excel using VLOOKUP are as follows: First, when the two column’s data are lined up like below, we can use the VLOOKUP function to see whether column 1 includes column 2. For the example supplied, this would be 17 columns. These can, of course, be hidden.Īll you need is a number of columns equivalent to the maximum of the numerals in the sets, after each of the original columns of your table. Although you would think a VBA solution is required, it is actually quite simple to do this with formulae, provided you use a lot of helper columns.
