Formula Trace

=HLOOKUP("Pencil", A1:D3, 2, FALSE)

Step 1: HLOOKUP("Pencil", A1:D3, 2, FALSE)

Cell Reference Map

    A       B       C       D
1 |Product | Pen   | Pencil | Eraser
2 | Price  | 1.5   | 0.5    | 0.75
3 | Stock  | 100   | 200    | 150

HLOOKUP searches row 1 (A1:D1) for "Pencil" and returns value from row 2 in the same column.

The formula looks for "Pencil" in the first row (A1:D1) and returns the value from the second row of the same column.

Result

    A       B       C       D
1 |Product | Pen   | Pencil | Eraser
2 | Price  | 1.5   | 0.5    | 0.75
3 | Stock  | 100   | 200    | 150

Result of formula in cell E1: 0.5

The formula returns 0.5, which is the price of the Pencil found in cell C2.

Sheet Trace Quiz - 3 Questions

What does the HLOOKUP function search for in the formula?

A "Pencil" in the first row

B Price in the second row

C Stock in the third row

D "Pencil" in the second row

Key Result

HLOOKUP looks for a value in the first row of a range and returns a value from a specified row in the same column.

Practice

1. What does the HLOOKUP function do in Excel?

easy

A. It adds all numbers in a horizontal range.

B. It searches for a value in the first column and returns a value from a specified column to the right.

C. It searches for a value in the top row and returns a value from a specified row below.

D. It sorts data horizontally in ascending order.

Solution

1. Step 1: Understand the function purpose

   The HLOOKUP function looks horizontally in the top row of a table to find a match.

2. Step 2: Identify the return value

   Once it finds the match, it returns a value from a specified row below that top row.

3. Final Answer:

   It searches for a value in the top row and returns a value from a specified row below. -> Option C

4. Quick Check:

   HLOOKUP = horizontal lookup [OK]

Hint: HLOOKUP looks horizontally in the top row for a match [OK]

Common Mistakes:

• Confusing HLOOKUP with VLOOKUP which searches vertically
• Thinking it sums values instead of looking up
• Assuming it sorts data

2. Which of the following is the correct syntax for the HLOOKUP function?

easy

A. HLOOKUP(lookup_value, row_index_num, table_array, [range_lookup])

B. HLOOKUP(table_array, lookup_value, row_index_num, [range_lookup])

C. HLOOKUP(row_index_num, lookup_value, table_array, [range_lookup])

D. HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

Solution

1. Step 1: Recall the function parameter order

   The correct order is: lookup_value, table_array, row_index_num, and optional range_lookup.

2. Step 2: Match with options

   HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup]) matches this order exactly.

3. Final Answer:

   HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup]) -> Option D

4. Quick Check:

   Syntax order matters in HLOOKUP [OK]

Hint: Remember: lookup_value first, then table, then row number [OK]

Common Mistakes:

• Swapping lookup_value and table_array
• Putting row_index_num before table_array
• Omitting required parameters

3. Given the table below in cells A1:D3:

	Jan	Feb	Mar
Sales	100	150	200
Profit	30	50	70

What is the result of =HLOOKUP("Feb", A1:D3, 3, FALSE)?

medium

A. 70

B. 150

C. 50

D. Error

Solution

1. Step 1: Locate "Feb" in the top row

   "Feb" is found in cell C1, which is the third column.

2. Step 2: Return value from row 3 in that column

   Row 3, column C contains 70 (Profit for Feb).

3. Final Answer:

   70 -> Option A

4. Quick Check:

   HLOOKUP finds Feb then returns row 3 value 70 [OK]

Hint: Match top row, then pick value from given row number [OK]

Common Mistakes:

• Returning value from wrong row (e.g., row 2 instead of 3)
• Confusing columns and rows
• Using approximate match instead of exact

4. You wrote the formula =HLOOKUP("Q2", A1:D3, 2) but it returns incorrect data. What is the likely problem?

medium

A. You forgot to set the fourth argument to FALSE for exact match.

B. The lookup_value "Q2" is not in the top row of the table.

C. The row_index_num is too high and exceeds the table rows.

D. The table_array is missing dollar signs ($) for absolute reference.

Solution

1. Step 1: Check if lookup_value exists in top row

   If "Q2" is not found in the top row, HLOOKUP cannot find a match.

2. Step 2: Understand impact of missing lookup_value

   Without the value, the function returns wrong or #N/A error regardless of other parameters.

3. Final Answer:

   The lookup_value "Q2" is not in the top row of the table. -> Option B

4. Quick Check:

   Lookup value must be in top row [OK]

Hint: Ensure lookup_value is exactly in the top row [OK]

Common Mistakes:

• Assuming approximate match works without FALSE
• Using wrong row_index_num
• Thinking absolute references fix lookup errors

5. You have a table with months in the top row (A1:D1) and sales data in rows below. You want to find the sales for "Mar" but the months are not sorted alphabetically. Which formula will always return the exact sales value for "Mar"?

hard

A. =HLOOKUP("Mar", A1:D3, 2, FALSE)

B. =HLOOKUP("Mar", A1:D3, 2)

C. =HLOOKUP("Mar", A1:D3, 3)

D. =HLOOKUP("Mar", A1:D3, 2, TRUE)

Solution

1. Step 1: Understand the range_lookup argument

   TRUE or omitted means approximate match, which requires sorted top row.

2. Step 2: Choose exact match for unsorted data

   FALSE forces exact match, so it works even if months are not sorted.

3. Step 3: Verify row_index_num

   Row 2 contains sales data, so row_index_num should be 2.

4. Final Answer:

   =HLOOKUP("Mar", A1:D3, 2, FALSE) -> Option A

5. Quick Check:

   Use FALSE for exact match with unsorted data [OK]

Hint: Use FALSE for exact match when data is unsorted [OK]

Common Mistakes:

• Omitting FALSE and getting wrong approximate results
• Using wrong row_index_num
• Assuming TRUE works for unsorted data
