The HLOOKUP function in Excel is a search tool similar to VLOOKUP, but it works horizontally. It looks for a value in the first row of a table and returns a related value from another row in the same column. This is especially useful when your data is arranged in rows instead of columns.
What is the HLOOKUP Function?
HLOOKUP stands for Horizontal Lookup. It searches across the first row of a table until it finds a match, then returns a value from the row you choose.
HLOOKUP is often used when data is organized by categories in the first row, such as months, years, or product names.
Syntax of the HLOOKUP Function:
=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
- lookup_value: The value you want to find in the first row.
- table_array: The range of cells containing the data (must include the row you search in and the row you return from).
- row_index_num: The row number (in the table_array) from which to return the value.
- [range_lookup]: TRUE (approximate match) or FALSE (exact match).
Where Can We Use the HLOOKUP Function?
The HLOOKUP function is helpful in scenarios such as:
- Finding Monthly Data: Look up a value for a specific month.
- Yearly Reports: Get values for a specific year from summary tables.
- Matching Categories to Data: Match a header name to the correct row of data.
- Timetables: Find scheduled activities for a specific day or time.
- Inventory Across Months: Track stock or sales by month.
How to Use the HLOOKUP Function in Different Methods
Here are four common methods to use HLOOKUP in Excel:
Method 1: Exact Match Lookup
This method finds an exact match for your lookup value in the first row.
Steps:
- Enter your data. For example:
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Item | Apple | Banana | Orange |
| 2 | Price | 1.5 | 0.8 | 1.2 |
- In cell F1, type your lookup value (e.g.,
Banana). - In cell G1, type:
=HLOOKUP(F1, A1:D2, 2, FALSE) - Press Enter. The result (0.8) will appear.
Live Example:
| Lookup Value | Formula | Result |
|---|---|---|
| Banana | =HLOOKUP(F1, A1:D2, 2, FALSE) | 0.8 |
Method 2: Approximate Match Lookup
When your lookup value is not an exact match, HLOOKUP can find the closest lower value (works well with number ranges).
Steps:
- Enter your data. For example:
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Score | 0 | 50 | 85 |
| 2 | Grade | F | C | A |
- In cell F1, type a score (e.g.,
72). - In cell G1, type:
=HLOOKUP(F1, A1:D2, 2, TRUE) - Press Enter. The result (C) will appear.
Method 3: Using a Cell Reference for Dynamic Lookup
You can make your lookup value change dynamically by referencing another cell.
Steps:
- Use the table from Method 1.
- In F1, type the fruit name you want (e.g.,
Apple). - In G1, type:
=HLOOKUP(F1, A1:D2, 2, FALSE) - Press Enter. The result (1.5) will appear.
Method 4: Handling Errors with IFERROR
If the lookup value is not found, HLOOKUP will return #N/A. You can use IFERROR to show a friendly message instead.
Steps:
- Use the same table from Method 1.
- In F1, type a fruit name not in the list (e.g.,
Mango). - In G1, type:
=IFERROR(HLOOKUP(F1, A1:D2, 2, FALSE), "Not Found") - Press Enter. The result (“Not Found”) will appear.

Data Setup:
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Item | Apple | Banana | Orange |
| 2 | Price | 1.5 | 0.8 | 1.2 |
Goal:
Look up prices based on fruit names in the first row.
Step 1: Enter the table in A1:D2.
Step 2: Enter lookup values in Column F.
Step 3: Apply HLOOKUP formulas in Column G.
Final Table:
| Lookup Value | Result | Formula |
|---|---|---|
| Banana | 0.8 | =HLOOKUP(F2, A1:D2, 2, FALSE) |
| Apple | 1.5 | =HLOOKUP(F3, A1:D2, 2, FALSE) |
| Mango | Not Found | =IFERROR(HLOOKUP(F4, A1:D2, 2, FALSE), “Not Found”) |
Key Notes About the HLOOKUP Function
- Searches Horizontally: Always searches in the first row of the range.
- Row Number: The row number in the table_array starts at 1 (top row).
- Exact vs Approximate: Use FALSE for exact matches, TRUE for approximate matches.
- Cannot Look Upwards: HLOOKUP only returns values below the first row.
- Error Handling: Use IFERROR to show custom messages instead of error codes.
Conclusion
The HLOOKUP function in Excel is a great tool for searching horizontally arranged data. Whether you’re looking up prices, grades, or any other information stored in rows, HLOOKUP makes the process quick and easy.
By learning both exact and approximate match options, and using error handling, you can make your lookups more accurate and user-friendly. Practice with real-world datasets to gain confidence using HLOOKUP alongside VLOOKUP.
