Horizontal lookup. Searches across the first row of a range for a key and returns the value of a specified cell in the column found.

Sample Usage

HLOOKUP(10003, A2:Z6, 2, FALSE)


HLOOKUP(search_key, range, index, [is_sorted])

  • search_key - The value to search for. For example, 42, "Cats", or I24.

  • range - The range to consider for the search. The first row in the range is searched for the key specified in search_key.

  • index - The row index of the value to be returned, where the first row in range is numbered 1.

    • If index is not between 1 and the number of rows in range, #VALUE! is returned.
  • is_sorted - [OPTIONAL - TRUE by default] - Indicates whether the row to be searched (the first row of the specified range) is sorted.

    • If is_sorted is TRUE or omitted, the nearest match (less than or equal to the search key) is returned. If all values in the search row are greater than the search key, #N/A is returned.

    • If is_sorted is set to TRUE or omitted, and the first row of the range is not in sorted order, an incorrect value might be returned.

    • If is_sorted is FALSE, only an exact match is returned. If there are multiple matching values, the content of the cell corresponding to the first value found is returned, and #N/A is returned if no such value is found.


  • When searching for numeric or date values, make sure that the first row in the range is not sorted by text values. For example, correctly sorted numbers should appear as (1, 2, 10, 100) rather than (1, 10, 100, 2) as they would be if they were sorted as strings. Using an incorrect sort type may cause incorrect values to be returned.

  • Search keys based on regular expressions or wildcard patterns are NOT supported. Use QUERY instead.

  • HLOOKUP has much better performance with sorted ranges and is_sorted set to TRUE. Consider sorting the row being searched.

In this example, HLOOKUP searches across the first row for a student ID and returns the corresponding grade.

In this example, HLOOKUP searches across the first row for the income using approximate match (is_sorted is set to TRUE) and returns the corresponding tax rate.

In this example, HLOOKUP returns the first value found when there are multiple matches for the search_key.
