When processing Excel data, it is often necessary to find and match the same items from two different tables. At this time, the VLOOKUP function becomes a very practical tool. Simply put, the VLOOKUP function searches for a specific value in a column of a table and returns the value of another cell in the same row. To match the same items in two tables, the main steps include selecting the search value, determining the table array, specifying the number of column indexes, and setting the search range. Among them, choosing the correct lookup value is particularly critical, because the lookup value is the basis for matching by the VLOOKUP function, and it must be ensured that the value being looked up is unique and accurate in the source table.
Next, we will delve into how to effectively use the VLOOKUP function to match the same items in two tables.
The basic syntax of the VLOOKUP function is: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup]), where each parameter has important meaning:
lookup_value: Lookup value, that is, the value you need to find in the table array. table_array: table array, the data area in the table you want to search. col_index_num: column index number, column number in the table array, the first column is 1, indicating which column value is returned from the matching search value row. range_lookup: search range, optional parameter. TRUE indicates an approximate match, FALSE indicates an exact match.Selecting an appropriate lookup value is a prerequisite for successful matching using the VLOOKUP function. First, make sure that there is a common field in both tables that can be used as a matching basis, such as employee number, product code, etc. The search value should be unique and should not contain duplicate or ambiguous items. If there are problems with the original data, it may be necessary to clean and organize the data first.
After you determine the lookup value, you need to quote it correctly in the VLOOKUP function. This usually means placing the lookup value in the function's first argument position, and making sure the value is in the left-most column of the source data table.
In the VLOOKUP function, the table array is the setting of the search range. The table array should cover the columns containing the lookup values and the columns that need to be returned. The choice of table array directly affects the search efficiency and accuracy of the VLOOKUP function.
When selecting a table array, it should be noted that although the entire table can be selected, the best practice is to only include necessary columns to improve search efficiency and reduce the probability of errors. In addition, it is best to use absolute references for table array references (that is, add a $ sign before the column and row labels), so as to avoid unnecessary errors when copying formulas.
The column index number refers to which column in the table array you want the returned data to be located. This number is counted starting from the leftmost column of the table array. For example, if you wish to return data for the third column of the row where the value is found in the first column of the table array, the column index number should be set to 3.
In actual operation, special attention is required when determining the number of column indexes, especially when the table array selects a large number of columns. Ensure that column positions are calculated correctly and avoid common mistakes such as confusing column index numbers with the actual full table positions of the required columns.
The last step is to set the search range, that is, decide whether to perform an exact match or an approximate match. In most cases, it is recommended to use exact matching (i.e. set range_lookup to FALSE). This ensures that the VLOOKUP function will only look for items with the exact same value as the lookup value.
Exact matching is the most common choice for processing data matching between different tables, especially when the data you are processing requires strict correspondence. Although approximate matching also has its application scenarios, such as finding data intervals or grading, it is usually not the first choice when matching data between tables.
Through the above steps, you can use the VLOOKUP function to perform effective data matching in the two tables. This powerful function can greatly improve the efficiency of data processing and is one of the indispensable skills for efficient data processing in Excel. Proper use of the VLOOKUP function can not only help you quickly find relevant data, but also ensure the accuracy and consistency of the data.
1. How does VLOOKUP match identical items in two tables?
The VLOOKUP function is a very useful function in Excel that can match the same items in two tables. Here are some steps to use the VLOOKUP function for identical items matching:
First, make sure there is a common column or value in both tables so they can match. Suppose we have two tables A and B, and want to find matches in table A for table B. Create a new column in table A to store the results of the VLOOKUP function. The syntax for using the VLOOKUP function: Enter =VLOOKUP(value to find, search range, returned column index, exact match) in the new column. The value to be found is the value in table B, the search range is the column in table A, and the column index returned is the index number of the column in table A that matches the value we are looking for. Exact match is an optional parameter. If set to FALSE or 0, an approximate match will be performed. If set to TRUE or 1, an exact match will be performed. In most cases, exact match is the better choice. Drag the small box in the lower right corner below to apply the VLOOKUP function to the entire new column.2.

How to use the VLOOKUP function to match the same items in two different tables?
To match the same items in two different tables, you can use the VLOOKUP function in Excel. Here are some steps:
First, find common columns or common values in the two tables, which will be the basis for our matching. In a table, create a new column to store the results of the VLOOKUP function. The syntax for using the VLOOKUP function in a new column: "=VLOOKUP(value to be found, search range, returned column index, exact match)". The value to be found is a value in another table, the search range is a column in the first table, and the column index returned is the index number of the column that matches the value we are looking for. Exact match is an optional parameter that can be set to FALSE or 0 for an approximate match, or to TRUE or 1 for an exact match. Drag the small box in the lower right corner below to apply the VLOOKUP function to the entire new column to match all values.All in all, mastering the VLOOKUP function can greatly improve the efficiency of Excel data processing and is an important skill that every Excel user should master. I hope this article can help readers better understand and use the VLOOKUP function for data matching.
