Difference Between VLOOKUP and HLOOKUP

In MS Excel, knowing the difference between VLOOKUP and HLOOKUP is essential because they work differently. VLOOKUP searches for data vertically, while HLOOKUP searches horizontally, based on how your data is arranged, which affects how you retrieve information from your spreadsheet. Read our blog to learn more about the difference between VLOOKUP and HLOOKUP.

What is VLOOKUP?

VLOOKUP or Vertical Lookup is a lookup function in Microsoft Excel and Google Sheets to find specific information based on a reference value. It works by searching vertically down a specific column for a matching value. It then retrieves data from a different column in the same row.

What is HLOOKUP?

HLOOKUP, or Horizontal Lookup, is another lookup function. Unlike VLOOKUP, which searches vertically down a column, HLOOKUP searches horizontally across a specific row for a matching value. Once it finds the matching value, it retrieves data from a different row in the same column. 

Tabular Comparison - VLOOKUP vs HLOOKUP 

The main difference between VLOOKUP and HLOOKUP is their search direction: VLOOKUP searches vertically in a table from top to bottom, while HLOOKUP searches horizontally from left to right. Let us explore some more such differences.

Detailed Comparison - VLOOKUP vs HLOOKUP 

Understanding these differences is essential for effectively utilising either function based on the layout and structure of your data in Excel. 

Table Orientation

• VLOOKUP: Imagine your data arranged like a list, with categories on the left side. VLOOKUP works best when you have this kind of setup.
• HLOOKUP: Think of your data arranged like a table, with categories along the top row. HLOOKUP is designed for this layout.

Popularity and Usage

• VLOOKUP is among the most popular Excel functions. It's used for various tasks, given it is pretty straightforward and powerful to work with.
• HLOOKUP, on the other hand, is less commonly used. It has its specific uses but is still less popular than VLOOKUP.

Output Orientation

• Both functions do the same thing: look up information. However, VLOOKUP finds information in rows (like skimming down a list)
• HLOOKUP looks for information across columns (like reading across a table).

Formula Structure

• VLOOKUP formula looks like this: 

=VLOOKUP(lookup_value, table_array, col_index_number, [range_lookup]). 

Notice the "col_index_number" part—it tells Excel which column to look in for the desired information.

• HLOOKUP formula is similar: 

=HLOOKUP(lookup_value, table_array, row_index_number, [range_lookup]). 

"row_index_number" tells Excel which row to search for the desired information.

Position of Lookup Data

• VLOOKUP finds data based on a value you provide in your table's leftmost column.
• HLOOKUP searches for data based on a value in your table's bottom-most row.

Conclusion

Both VLOOKUP and HLOOKUP are powerful functions that facilitate data retrieval in MS Excel; however, their application depends on the orientation of the data. VLOOKUP is more commonly used, given its ease in vertical data arrangements, while HLOOKUP is less frequently employed but remains valuable for specific scenarios where data is organized horizontally. By mastering both functions, users can enhance their data analysis capabilities and streamline their workflow in Excel.
