I have a dataset on excel with more than 40k entries, and there are 2 columns.
I want to find if there exists an entry for example with 1 in the first column and 1687 in the second column, I tried using this following IF function:
=IF(COUNTIF(B2:B178,"1687"),"Yes","No)
where A1:A178 have 1 in the first column.
This function works perfectly alright, however in terms of selecting the range for Countif, it requires much work as sometimes the range i have is more than 3 to 4k. This is way too time consuming as I have to repeat this search for many pairs of numbers.
I then tried by adding a helper column, where the 1st entry would be "=A2&B2" My plan was to search this entire helper column for "11687" instead, however this fails to identify entries where it has 1 in the first column, 1687 in the second, and 11 in the first column, and 687 in the second column.
Ideally if the "find" function (Ctrl+F) could find 2 columns for different values it will be exactly what I need.
Could anyone please advise me on how to do this search?
Thank you very much!

Change your range into a table and use built in Excel filtering capabilities. See http://office.microsoft.com/en-001/excel-help/filter-data-in-a-range-or-table-HP010073941.aspx#BMfilter_text

Try this formula and fill it all the way down, should be more efficient than COUNTIF
:
=IF(AND($A1="1",$B1="1687"),TRUE,FALSE)
Then you have a column of TRUE
/FALSE
that you can use to do what you want.
