How to return an array where a column matches a value

问题

I am trying to create the column _Type_below which return the type value for a matching name AND a matching interval. I know I can use VLOOKUP for individual names, but lets say I have thousands of names and I can specify an array for VLOOKUP for all of them. Cheers!!

Name   position             _Type_             Name    Range_From      Range_To     Type
bob    0                      A                bob     0               30            A
bob    5                      A                bob     30              100           B
bob    10                     A                doug    0               40            C
bob    15                     A                doug    40              200           A
bob    20                     A
bob    30                     B
bob    40                     B
bob    80                     B
doug   0                      C
doug   20                     C
doug   40                     A
...

If yu have the dynamic array formula you can use FILTER():

 =VLOOKUP(B2,FILTER(E:G,A2=D:D),3)

---

If not then your data must be sorted on D then E:

=VLOOKUP(B2,INDEX(E:E,MATCH(A2,D:D,0)):INDEX(G:G,MATCH(A2,D:D,0)+COUNTIF(D:D,A2)-1),3)

This should be relatively quick, but it requires the data sorted.

You can go super old fashioned and get the row using SumProduct() and pass that into Index(). It's not going to be speedy though.

=INDEX($I$1:$I$5, SUMPRODUCT(($F$1:$F$5=A2)*($G$1:$G$5<=B2)*($H$1:$H$5>B2)*ROW($F$1:$F$5)), 1)
