# VLookup then calculate

Posted on 2014-02-06

Could an expert provide me with the formula to do a Vlookup then perform a calculation.

Assume we start on Sheet1 on "E2"
i.e. Vlookup the Ref in A2 [Sheet1] on sheet3 column 'A', if it is there in Sheet3 find the number in column 'C' and then increase the date in Sheet1 by that number of months.

So. If my date in Sheet1 is 14/3/2014 and the number in Sheet 3 is 4 put 14/7/2014 in column 'C' in Sheet1

So. If my date in Sheet1 is 14/3/2014 and the number in Sheet 3 is 12 put 14/7/2015 in column 'C' in Sheet1

Hope this is clear.
Thanks

Hi,

pls use

=EDATE(E2,Sheet3!A2)
E2 is your date in Sheet 1 and the amount of Months in sheet3

you can use this formula
=DATE(YEAR(E3);MONTH(E3)+VLOOKUP(E3;Sheet3!\$A\$1:\$C\$4;3;FALSE);DAY(E3))

or

=EDATE(E2;VLOOKUP(E3;Sheet3!\$A\$1:\$C\$4;3;FALSE))

check in my sample as well

Thanks for the replies which I will look at however, I have just been informed that the user is looking for something even more complicated. I have attached a file to explain. They are looking for me to include :

If date 1 is weekend populate last working day.
If date 2 is weekend populate next working day

Rgonzo1971 from what I can make out with your formula, it does not take into account the Ref it needs to look up in Sheet1

yes, Rgonzo forgot to implement lookup formula (VLOOKUP) into his calculation.

Also question is if dates in Sheet3 are unique. BEcause if not and you have the same date in row 2 and in row 10 (because its the same date but for diferent employee) VLOOKUP formala wont work (OK, it will be but always takes a C value from the 1st date it finds, so from row 2)

Hi Gowflow. thanks but not quite.

I need to lookup the frequencyin Sheet3 and populate in sheet1 against its respective Ref.

So I lookup 6290614 [A2 in Sheet1] see if that is in sheet 3 find the frequncy and put this in Sheet 1 column D. [I can do this as it's an easy Vlookup]

i.e. [I have used row 12 from the spreadsheet as it is better to show the detail]
Ref      Date1                          Date2            Frequency
25922383      24/01/2014      25/01/2014      12

Then perform the second part of the formula. I now need to increase Date 1 and Date 2 by the frequency taking into account

If date 1 is weekend populate last working day.
If date 2 is weekend populate next working day

so:

Ref      Date1          Date2            Frequency        NextDate1                  NextDate2

25922383      24/01/2014  25/01/2014      12      23/01/2015      25/01/2015

Hi,

Shouldn't be the NextDate2 26.1.2015 Monday after the W-E
