HLOOKUP

Description: Searches for a specified value in an array or table, based on the value found in the first row. Use HLOOKUP when your comparison values are located in a row across the top of a table of data and you want to look down a specified number of rows. Use VLOOKUP when your comparison values are located in a column to the left of the data you want to find.

Syntax: HLOOKUP(Lookup_value, Table_array, Row_index_number, [Range_lookup])

Lookup_value is the value to be found in the first row of the table. Lookup_value can be a value, a reference, or a text string.
Table_array is a table of information in which data is looked up. Use a reference to a range or a range name.

The values in the first row of Table_array can be text, numbers, or logical values.

If Range_lookup is TRUE, the values in the first row of Table_array must be placed in ascending order: ...-2, -1, 0, 1, 2,... , A-Z, FALSE, TRUE; otherwise, HLOOKUP may not give the correct value. If Range_lookup is FALSE, Table_array does not need to be sorted.

Uppercase and lowercase text are equivalent.

You can put values in ascending order, left to right, by selecting the values and then choosing Sheet > Sheet Actions > Sort > Custom Sort. In the Sort window, select Columns and then Ascending.

Row_index_number is the row number in Table_array from which the matching value will be returned. A Row_index_number of 1 returns the first row value in Table_array, a Row_index_number of 2 returns the second row value in Table_array, and so on. Row_index_number must be greater than or equal to 1 and less than or equal to the number of rows on Table_array.
Range_lookup is a logical value that specifies whether you want HLOOKUP to find an exact match or an approximate match. If Range_lookup is TRUE or omitted, an approximate match is returned. In other words, if an exact match is not found, the next largest value that is less than Lookup_value is returned. If FALSE, HLOOKUP will find an exact match. If one is not found, the error value #N/A is returned.

Remarks:

If HLOOKUP can't find Lookup_value, and Range_lookup is TRUE, it uses the largest value that is less than Lookup_value.
If Lookup_value is smaller than the smallest value in the first row of Table_array, HLOOKUP returns the #N/A error value.
If Range_lookup is FALSE and Lookup_value is text, you can use the wildcard characters, question mark (?) and asterisk (*), in Lookup_value. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.

Example:

Suppose you have an inventory worksheet of auto parts. A1:A4 contains the following data, respectively: Axles, 4, 5, 6. B1:B4 contains the following data, respectively: Bearings, 4, 7, 8. C1:C4 contains the following data, respectively: Bolts, 9, 10, 11.

HLOOKUP("Axles", A1:C4, 2, TRUE) = 4
HLOOKUP("Bearings", A1:C4, 3, FALSE) = 7
HLOOKUP("Bearings", A1:C4, 3, TRUE) = 7
HLOOKUP("Bolts", A1:C4, 4,) = 11
HLOOKUP(3,{1, 2, 3; "a", "b", "c"; "d", "e", "f"}, 2, TRUE) = c
