在Excel中获取当月右侧的单元格

Question

I'm pretty new to Excel, that question is probably easy, but I dont know what to do :-(. So this is what I have:

Date        Numbers
01.09.11      10   
01.10.11      20
01.11.11      30
01.12.11      40

Now what I want is in another cell: Get the number of the date, where the date's month is the current month. How do I do this?

Answer 1

Assuming all your dates are strings of the form "dd.mm.yy", you can use the following array formula:

=INDEX(B1:B4,MATCH(9,VALUE(MID(A1:A4,4,2)),0))

where the 9 is the month number you want to look up. Enter this as an array formula by pressing Ctrl+Shift+Enter.

EDIT:

As pointed out in the comments, you want to match the current month, so incorporating @JMax's suggestion works:

=INDEX(B1:B4,MATCH(MONTH(TODAY()),VALUE(MID(A1:A4,4,2)),0))

To clear up any confusion, MID() returns a string, which by itself will not return a match for the number value returned by MONTH(TODAY()) . However, if you stick the MID() function inside a VALUE() function, the string returned by MID() will be converted into a number value. Eg, "09" becomes the number 9, "10" becomes the number 10. This allows you to match the number value returned by MONTH(TODAY()) .

However, if your dates are entered as dates with format dd.mm.yy in your sheet instead of as strings, then you can use the same strategy but with a different matching term:

=INDEX(B1:B4,MATCH(MONTH(TODAY()),MONTH(A1:A4),0))

Enter this as an array formula.
