Excel公式在最接近或相等的日期返回值

Question

I'm working on an excel formula that will reference a table on a different worksheet in the same workbook and return a value based on the current date. Thus far I have been able to use this formula to return the value as I am intending. I've included an example table for the formula to show the methodology.

=VLOOKUP(TODAY(),TRANSACTIONS!A:D,4,FALSE)

While this works, the flaw is that it will return #N/A if there are no lines which have an exact matching date. In the case of the above table, the transactions don't occur daily so if the given date returned by TODAY() doesn't match any line in the shown table, it breaks the formula. My table also contains "planned" or "expected" transactions which exist into the future meaning I can't rely on the MAX() function to provide the correct result

With that said, I am looking for a tweak to this formula that will always return a value even if the current date doesn't match any rows exactly. Using the above image as a reference, if the date returned by TODAY() were to be 2/20/17, the result it should give should be the value in D5, 1566. Conversely if the date is 2/28/17, it should return the value in D7, 1182.

Open to any an all suggestions which will achieve these results. Let me know if you need any further clarification. Thanks!

Answer 1

I'd use

=IFERROR(VLOOKUP(E2,A:D,4,TRUE),D2)

so that should your date fall before the lowest in column A it'd return the first value of column D (ie the value in D2 cell)

Answer 2

在上面已经建议的IFERROR中，使用INDEX MATCH而不是VLOOKUP。
