vlookup 英文介绍
VLOOKUP is a popular function in Excel used to search for a specific value in the leftmost column of a table and return a corresponding value from a specified column. The term "VLOOKUP" stands for "Vertical Lookup" as it looks vertically in a table to find the desired value.
The syntax of the VLOOKUP function is as follows:
VLOOKUP(lookup_value, table_array, col_index_num, range_lookup)
- lookup_value: This is the value that you want to find in the leftmost column of the table.
- table_array: This refers to the range of cells that represents the table where you want to perform the lookup.
- col_index_num: This represents the column number in the table from which you want to retrieve the result.
-
range_lookup: This is an optional argument that specifies whether you want an exact match (FALSE) or an approximate match (TRUE) when searching for the lookup value.
Here is an example to demonstrate the usage of VLOOKUP:
Suppose you have a table with student names in column A and their corresponding grades in column B. You want to find the grade for a specific student. You can use the VLOOKUP function as follows:vlookup和column
=VLOOKUP("John", A1:B10, 2, FALSE)
This formula searches for the name "John" in column A and returns the corresponding grade from column B.
VLOOKUP is a powerful tool that can be used in various scenarios, such as data analysis, managing databases, or merging datasets. It helps in quickly retrieving information based on specific criteria, making it a valuable function in Excel.
