vlookup - find an alternative approximate match
With vlookup, and a range lookup value of TRUE, when there is no exact match,
is it possible to return the smallest value that is greater than the lookup value (rather than next largest value that is less than lookup value)? Thank you. |

vlookup - find an alternative approximate match
One way...
A1 = lookup_value G1:H10 = table_array Array entered** : =INDEX(H1:H10,MATCH(TRUE,G1:G10=A1,0)) ** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT key then hit ENTER. That would be the equivalent of: =VLOOKUP(A1,G1:H10,2,TRUE) Except it will return the *next higher* value when an exact match isn't found. -- Biff Microsoft Excel MVP "Graeme" wrote in message ...

Another way - *non* array option:
With datalist in A1 to B20, and lookup value in C1, try this: =INDEX(B1:B20,MATCH(SMALL(A1:A20,COUNTIF(A1:A20,"< "&C1)+1),A1:A20,0)) -- HTH, RD --------------------------------------------------------------------------- Please keep all correspondence within the NewsGroup, so all may benefit ! --------------------------------------------------------------------------- "Graeme" wrote in message ...

The MATCH and SMALL calls are superfluous when the first column of the lookup range is sorted in ascending order. The general form =INDEX(table,COUNTIF(INDEX(table,0,1),"<"&value_so ught) +1,column_sought) and the particular form matching your formula =INDEX(B1:B20,COUNTIF(A1:A20,"<"&C1)+1) produce the desired result. Further, these forms work when col A contains text. |

Point well taken Harlan!
My test data wasn't sorted, but in retrospect, it should definitely have been, since the OP's entire question revolved around *inexact* matches. -- Regards, RD --------------------------------------------------------------------------- Please keep all correspondence within the NewsGroup, so all may benefit ! --------------------------------------------------------------------------- "Harlan Grove" wrote in message ...
