How do I do a VLOOKUP from another sheet in Excel? Mastering VLOOKUP in Excel is akin to discovering a secret pathway in a maze, leading directly to the treasure you seek. This powerful tool is indispensable when navigating through the vast seas of data that modern spreadsheets often become. Whether it's pinpointing an employee's department from a sprawling corporate directory or fetching a specific contact number from a dense database, VLOOKUP stands ready as your digital sleuth. Embarking on the journey of understanding how to use Excel VLOOKUP involves mastering a sequence of steps that transform this seemingly arcane formula into a straightforward and indispensable ally in data management.

1. Lecture Notes on Excel's VLOOKUP and
XLOOKUP Functions
Introduction to Lookup Functions in Excel
Overview
Lookup functions are essential tools in Excel that facilitate data analysis by searching for data
within a dataset and retrieving corresponding values. They are crucial for managing large
datasets, automating data retrieval, and enhancing productivity.
Differentiating Lookup Functions
Excel offers several lookup functions, each with unique capabilities:
• VLOOKUP (Vertical Lookup): Searches for a value in the first column of a table to
return a value in the same row from a specified column.
• HLOOKUP (Horizontal Lookup): Similar to VLOOKUP, but searches for a value in
the first row.
• XLOOKUP: A modern replacement for VLOOKUP and HLOOKUP, offering greater
flexibility.
• LOOKUP: A simpler form of lookup function that can perform both vertical and
horizontal lookups but with limitations.

2. Understanding VLOOKUP
Definition
VLOOKUP stands for Vertical Lookup. It is designed to search for a specific value in the first
column of a table array and return a value from the same row in a column you specify.
Syntax
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Parameters Explained
• lookup_value: The value Excel searches for in the first column.
• table_array: The cell range containing the data.
• col_index_num: The column number in the table from which to retrieve the value.
• range_lookup: Optional. Use TRUE for an approximate match or FALSE for an exact
match.
Practical Examples
• Finding employee details from a master list.
• Matching product names to their corresponding prices.
VLOOKUP from Another Sheet
Syntax for cross-sheet VLOOKUP: =VLOKUP(lookup_value, Sheet2!range,
col_index_num, [range_lookup]) This section discusses referencing tables across different
Excel sheets.

3. Troubleshooting Common VLOOKUP Issues
Common issues include mismatches in data type, incorrect table array, and the lookup value not
being in the first column. Solutions involve ensuring data format consistency, correct
referencing, and using absolute references for table arrays.
Introduction to XLOOKUP
Definition
XLOOKUP is designed to overcome the limitations of VLOOKUP by providing a more
flexible and powerful lookup function.
Syntax
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode],
[search_mode])
Advantages over VLOOKUP
XLOOKUP can search in any direction, does not require specifying a column index number,
and includes built-in error handling.
Comparing VLOOKUP and XLOOKUP
Main differences include the directionality of the search, the requirement for column index
numbers with VLOOKUP, and XLOOKUP's enhanced ability to handle missing values. Use
cases may determine the choice between the two.
Introduction to Lookup Functions in Excel
Lookup functions are essential tools in Excel for data analysis, enabling users to search for
information within a dataset and return corresponding values. Among these functions,

different purposes and offering various features to handle data efficiently.
Understanding VLOOKUP
Definition
VLOOKUP stands for Vertical Lookup. It is designed to search for a value vertically in the
first column of a table and return a value from the same row in a specified column.
Syntax
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Parameters
• lookup_value: The value to search for.
• table_array: The range of cells containing the data.
• col_index_num: The column number from which to retrieve the value.
• range_lookup: Optional. Use TRUE for an approximate match and FALSE for an exact
match.
Practical Examples of VLOOKUP
1. Finding Employee Details: Suppose you have a master list of employees in one table
and need to find specific details like department or contact information. VLOOKUP can
search for the employee's name and return the requested details.
Example Code:
excelCopy code
=VLOOKUP("John Smith", A1:D100, 3, FALSE)

5. This formula searches for "John Smith" in the first column of the table range A1:D100 and
returns the value from the third column in the same row where "John Smith" is found.
2. Matching Product Names to Prices: To find the price of a product listed in a table.
Example Code:
=VLOOKUP("Widget A", Products!A2:B100, 2, TRUE)
VLOOKUP from Another Sheet
To reference tables across different sheets, include the sheet name followed by an exclamation
mark before the range.
Syntax: =VLOOKUP(lookup_value, Sheet2!range, col_index_num, [range_lookup])
Troubleshooting Common VLOOKUP Issues
• Mismatch in Data Type: Ensure both the lookup value and the table array have
consistent data formats.
• Incorrect Table Array: Verify the range includes the correct columns.
• Lookup Value Not in the First Column: VLOOKUP cannot find values in columns to
the right of the search column.
Introduction to XLOOKUP
Definition
XLOOKUP is designed to overcome the limitations of VLOOKUP, offering more flexibility
and functionality.

6. Syntax
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode],
[search_mode])
Advantages over VLOOKUP
• Searches both left and right of the lookup array.
• Does not require column index numbers.
• Built-in error handling with [if_not_found].
Comparing VLOOKUP and XLOOKUP
• Directionality of Search: XLOOKUP can search in both directions, unlike VLOOKUP.
• Column Index Numbers: XLOOKUP does not require them, simplifying the formula.
• Handling Missing Values: XLOOKUP allows specifying a value to return if the lookup
value is not found.
Step-by-Step Guide to Using XLOOKUP
Basic Example
To find an employee's department using their name:
excelCopy code
=XLOOKUP("John Smith", A1:A100, B1:B100, "Not Found")
This searches for "John Smith" in A1:A100 and returns the corresponding department from
B1:B100. If not found, it returns "Not Found".

7. Advanced Usage
Using [match_mode] and [search_mode] to customize searches, such as case-sensitive
searches or searching from the end of the array.
Transitioning from VLOOKUP to XLOOKUP
For existing Excel users, understanding the additional parameters and flexibility of XLOOKUP
is key. Practice with real-world scenarios to gain familiarity.
Compatibility Considerations
XLOOKUP is not available in older versions of Excel. Users should ensure compatibility before
sharing files.
Practice Exercises
1. Employee Lookup: Given a list of employee IDs and names on one sheet and a list of
IDs and emails on another, use VLOOKUP/XLOOKUP to match emails to names.
2. Price List Update: A product list with names and prices needs to be updated with new
prices from a supplier's list. Practice using VLOOKUP to find and update prices.
3. Troubleshooting Exercise: Identify and correct a formula that returns incorrect results
due to an approximate match setting when it should be an exact match.
Conclusion and Resources
Understanding and effectively using VLOOKUP and XLOOKUP can significantly enhance
data analysis capabilities in Excel. For further exploration, consider online courses, Excel
forums, and Microsoft's documentation for advanced techniques and updates.
