如果查找值是日期，则无法进行vlookup

Question

   A                A       B
9/24/2017       9/24/2017   10
9/23/2017       9/24/2017   20
9/22/2017       9/23/2017   30
9/21/2017       9/24/2017   40
9/20/2017       9/23/2017   50
9/19/2017       9/24/2017   60
9/18/2017       9/24/2017   70

while comparing date value with date it returns formula only,

=vlookup(C4,M4:N19,2,FALSE)

do we need to change the data format before we lookup?

Answer 1

You need to make sure they have the same data format. If the lookup value has a date format the table array has a string format it won't match.
