Horizontal.
You can use HLOOKUP.
HLOOKUP is a Lookup and Reference function, not a logical function. It is used to search through a table that is arranged horizontally. You would search along a row to find a value, and then move to another row to get a value to return. The corresponding function VLOOKUP is used more often because data is more often arranged in columns rather than rows. See the related question below.
the h stands for horizontal lookup and the v stands for vertical. assume you have two columns and you want to know if there are any names in them that are the same. You can use v look up to tell you how many repeats there are. You can also do that with rows, but you use h lookup. ALso this function can be used to find a certain aspect about a item iin a table.
