## Purpose

## Return value

## Arguments

*lookup_value*- The value to look up.*table_array*- The table from which to retrieve data.*row_index*- The row number from which to retrieve data.*range_lookup*- [optional] A Boolean to indicate exact match or approximate match. Default = TRUE = approximate match.

## Syntax

## Usage notes

The HLOOKUP function can locate and retrieve a value from data in a *horizontal table*. Like the "V" in VLOOKUP which stands for "vertical", the "H" in HLOOKUP stands for "horizontal". The lookup values must appear in the *first* row of the table, moving horizontally to the right. HLOOKUP supports approximate and exact matching, and wildcards (* ?) for finding partial matches.

HLOOKUP searches for a value in the *first row* of a table. When it finds a match, it retrieves a value at that column from the row given. Use HLOOKUP when lookup values are located in the first row of a table. Use VLOOKUP when lookup values are located in the first column of a table.

HLOOKUP takes four arguments. The first argument, called *lookup_value*, is the value to look up. The second argument, *table_array*, is a range that contains the lookup table. The third argument, *row_index_num* is the row number in the table from which to retrieve a value. In the example shown, HLOOKUP is used to look up values from row 2 (Level) and row 3 (Bonus) in the table. The fourth and final argument, *range_lookup*, controls matching. Use TRUE or 1 for an approximate match and FALSE or 0 for an exact match.

### Example #1 - approximate match

In the example shown, the goal is to look up the correct Level and Bonus for the sales amounts in C5:C13. The lookup table is in H4:J6, which is the named range "table". Note this is an approximate match scenario. For each amount in C5:C13, the goal is to find the *best* match, not an *exact* match. To lookup Level, the formula in cell D5, copied down, is:

```
=HLOOKUP(C5,table,2,1) // get level
```

To get Bonus, the formula in E5, copied down, is:

```
=HLOOKUP(C5,table,3,1) // get bonus
```

Notice the only difference between the two formulas is the row index number: Level comes from row 2 in the lookup table, while Bonus comes from row 3. The match mode has been set explicitly to approximate match by providing the last argument, *range_lookup*, as 1.

### Example #2 - exact match

In the screen below, the goal is to look up the correct level for a numeric rating 1-4. In cell D5, the HLOOKUP formula, copied down, is:

```
=HLOOKUP(C5,table,2,FALSE) // exact match
```

where table is the named range G4:J5. Notice the last argument, *range_lookup* is set to FALSE to require an exact match.

### Notes

*Range_lookup*controls whether the lookup value needs to match exactly or not. The default is TRUE = allow non-exact match.- Set
*range_lookup*to FALSE to require an exact match. - If
*range_lookup*is omitted or TRUE, and no exact match is found, HLOOKUP will match the nearest value in the table that is*still less than the lookup value*. However, HLOOKUP will still match an exact value if one exists. - If
*range_lookup*is TRUE , lookup values in the first row of the table must be sorted in ascending order. Otherwise, HLOOKUP may return an incorrect or unexpected value. - If
*range_lookup*is FALSE (exact match), values in the first row of the lookup table do not need to be sorted.
