XLOOKUP function in Google Sheets - Cell-by-Cell Formula Trace

Sample Data

This table lists products in column A and their prices in column B. Cell D2 contains the product name to look up. We want to find the price of the product named in D2 using XLOOKUP.

Cell	Value
A1	Product
B1	Price
A2	Apple
B2	1.2
A3	Banana
B3	0.5
A4	Cherry
B4	2
D1	Lookup Product
D2	Banana
E1	Price Found

Formula Trace

=XLOOKUP(D2, A2:A4, B2:B4, "Not found")

Step 1: D2

Step 2: A2:A4

Step 3: B2:B4

Step 4: Find "Banana" in ["Apple", "Banana", "Cherry"]

Step 5: Return value at position 2 in [1.2, 0.5, 2.0]

Step 6: Final result

Cell Reference Map

    A       B       C       D       E
1 |Product |Price  |       |Lookup  |Price
  |        |       |       |Product |Found
2 |Apple   |1.2    |       |Banana  | 
3 |Banana  |0.5    |       |        | 
4 |Cherry  |2.0    |       |        | 

Arrows:
D2 --> A2:A4 (lookup array)
D2 --> B2:B4 (return array)

The formula looks up the value in D2 inside the range A2:A4 and returns the corresponding value from B2:B4.

Result

    A       B       C       D       E
1 |Product |Price  |       |Lookup  |Price
  |        |       |       |Product |Found
2 |Apple   |1.2    |       |Banana  |0.5
3 |Banana  |0.5    |       |        | 
4 |Cherry  |2.0    |       |        | 

The formula in E2 shows 0.5, which is the price of the product "Banana" found by XLOOKUP.

Sheet Trace Quiz - 3 Questions

What value does the formula look for in the lookup array?

A "Banana"

B "Apple"

C 0.5

D "Cherry"

Key Result

XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found]) searches lookup_array for lookup_value and returns corresponding value from return_array or if_not_found if not found.

Practice

1. What does the XLOOKUP function do in Google Sheets?

easy

A. It searches for a value in one column and returns a matching value from another column.

B. It adds up all numbers in a range.

C. It sorts data alphabetically.

D. It creates a chart from selected data.

Solution

1. Step 1: Understand the purpose of XLOOKUP

   XLOOKUP is designed to find a value in one list and return a related value from another list.

2. Step 2: Compare with other options

   Options B, C, and D describe different functions unrelated to XLOOKUP.

3. Final Answer:

   It searches for a value in one column and returns a matching value from another column. -> Option A

4. Quick Check:

   XLOOKUP finds and returns matching values [OK]

Hint: XLOOKUP matches and returns related data easily [OK]

Common Mistakes:

• Confusing XLOOKUP with SUM or SORT functions
• Thinking XLOOKUP creates charts
• Assuming XLOOKUP only works with numbers

2. Which of the following is the correct syntax for XLOOKUP in Google Sheets?

easy

A. =XLOOKUP(search_key, return_range, lookup_range)

B. =XLOOKUP(search_key, lookup_range, return_range, [if_not_found], [match_mode], [search_mode])

C. =XLOOKUP(lookup_range, search_key, return_range)

D. =XLOOKUP(return_range, search_key, lookup_range, [if_not_found])

Solution

1. Step 1: Recall XLOOKUP syntax

   The correct syntax is =XLOOKUP(search_key, lookup_range, return_range, [if_not_found], [match_mode], [search_mode]).

2. Step 2: Check each option

   =XLOOKUP(search_key, lookup_range, return_range, [if_not_found], [match_mode], [search_mode]) matches the correct order and optional arguments. Options A, B, and D have incorrect argument orders.

3. Final Answer:

   =XLOOKUP(search_key, lookup_range, return_range, [if_not_found], [match_mode], [search_mode]) -> Option B

4. Quick Check:

   Correct XLOOKUP syntax = =XLOOKUP(search_key, lookup_range, return_range, [if_not_found], [match_mode], [search_mode]) [OK]

Hint: Remember: search_key first, then lookup and return ranges [OK]

Common Mistakes:

• Swapping lookup_range and return_range
• Omitting required arguments
• Placing optional arguments in wrong order

3. Given the data:

A2:A5 = {101, 102, 103, 104}
B2:B5 = {"Apple", "Banana", "Cherry", "Date"}

What will =XLOOKUP(103, A2:A5, B2:B5) return?

medium

A. "Banana"

B. "Date"

C. "Cherry"

D. Error

Solution

1. Step 1: Identify the search key and lookup range

   The search key is 103, and the lookup range is A2:A5 containing {101, 102, 103, 104}.

2. Step 2: Find matching value and return corresponding value

   103 is found at the third position in A2:A5. The return range B2:B5 has "Cherry" at the third position.

3. Final Answer:

   "Cherry" -> Option C

4. Quick Check:

   103 matches Cherry [OK]

Hint: Match position of search key in lookup range to return range [OK]

Common Mistakes:

• Returning wrong position value
• Confusing lookup and return ranges
• Expecting error when value exists

4. What is wrong with this formula?

=XLOOKUP(105, A2:A5, B2:B5)

Given:
A2:A5 = {101, 102, 103, 104}
B2:B5 = {"Apple", "Banana", "Cherry", "Date"}

medium

A. The ranges have different sizes.

B. The lookup range and return range are swapped.

C. The formula syntax is incorrect.

D. The search key 105 is not found and no if_not_found argument is provided, so it returns an error.

Solution

1. Step 1: Check if search key exists in lookup range

   105 is not in A2:A5, so XLOOKUP cannot find a match.

2. Step 2: Understand behavior without if_not_found

   Without the optional if_not_found argument, XLOOKUP returns an error when no match is found.

3. Final Answer:

   The search key 105 is not found and no if_not_found argument is provided, so it returns an error. -> Option D

4. Quick Check:

   Missing if_not_found causes error on no match [OK]

Hint: Add if_not_found to avoid errors when no match [OK]

Common Mistakes:

• Assuming XLOOKUP returns blank instead of error
• Swapping lookup and return ranges
• Ignoring optional arguments

5. You have two columns:

Product IDs (A2:A6): {201, 202, 203, 204, 205}
Prices (B2:B6): {10, 15, 20, 25, 30}

You want to find the price for Product ID 206, but it does not exist. Which formula will return "Not Found" instead of an error?

hard

A. =XLOOKUP(206, A2:A6, B2:B6, "Not Found")

B. =XLOOKUP(206, A2:A6, B2:B6)

C. =XLOOKUP(206, B2:B6, A2:A6, "Not Found")

D. =XLOOKUP("Not Found", A2:A6, B2:B6, 206)

Solution

1. Step 1: Identify the correct syntax to handle missing values

   To avoid errors when the search key is missing, use the if_not_found argument with the desired message.

2. Step 2: Check each option

   =XLOOKUP(206, A2:A6, B2:B6, "Not Found") correctly uses "Not Found" as the if_not_found argument. =XLOOKUP(206, A2:A6, B2:B6) will return an error. =XLOOKUP(206, B2:B6, A2:A6, "Not Found") swaps lookup and return ranges incorrectly. =XLOOKUP("Not Found", A2:A6, B2:B6, 206) uses wrong argument order.

3. Final Answer:

   =XLOOKUP(206, A2:A6, B2:B6, "Not Found") -> Option A

4. Quick Check:

   Use if_not_found to show message on no match [OK]

Hint: Use 4th argument to show message if no match found [OK]

Common Mistakes:

• Swapping lookup and return ranges
• Omitting if_not_found argument
• Placing arguments in wrong order
