larkim Nov 2019 10:05am, 27 Nov 2019 9,597 posts	Quote Pin larkim Can someone write out the pseudo code for index match? In my head when I do a lookup I'm saying:- =Vlookup("Find this", "in the first column of this data", "and give me the value from this column", "and then I always type 'false’ because it doesn't work otherwise") Could you do the same for index match?

GlennR Nov 2019 10:31am, 27 Nov 2019 46,556 posts	Quote Pin GlennR Here you go: =INDEX($S$3:$W$282,MATCH($Z8,$A$3:$A$282,0),MATCH(AA$7,$S$2:$W$2,0)) $S$3:$W$282 is the range that contains the lookup data, in this case cost code tabulated against year. Column Z contains the cost code I want to look up, Row AA the year. $A$3:$A$282 is the array of cost codes. $S$2:$W$2 is the array of years. The formula looks at the data range and returns the figure at the row of the first MATCH and the column of the second. The zero at the end of the MATCH formulae makes the function look for an exact match.

SPR Nov 2019 10:37am, 27 Nov 2019 29,708 posts	Quote Pin SPR If you're using INDEX and MATCH like VLOOKUP INDEX (Column containing result, MATCH(Find this, In this Column, 0)) 0 = Exact Can also be typed as INDEX (Column containing result, MATCH(Find this, In this Column, 0), 1) The 1 at the end is unnecessary though if only one column is selected for the results bit.

larkim Nov 2019 10:42am, 27 Nov 2019 9,600 posts	Quote Pin larkim Ive not seen an index( match(), match()) formulation before. It'd still be nice to have the pseudo code done in my language And I'm consued with "Row AA" as I thought all rows were numerical? AA would be a column, no? Or am I wilfuly misunderstanding?
