دالة VLOOKUP في Excel 2010

Excel VLOOKUP function can be used when you need to look up the values in the specific table and check it against the other data fields for comparison purpose. VLOOKUP stands for Vertical lookup, used to find specific data from the datasheet. By creating a sample table generally referred as lookup table you can extract info from it and compare it with the desired field to yield required results. This post elaborates where you can use VLOOKUP  function.

Launch Excel 2010, and open a datasheet on which you want to apply VLOOKUP function.

For instance, we have included a student grading datasheet, containing fields; Name, Course, and Marks.

Now we will add new column Grade, which will contain grades secured by the students. Now for this, we will be using VLOOKUP function for looking up values from other table that contains sample data for grades.

Create two new columns containing marks range (sorted in any order) and corresponding grades. you don’t need to create them in a new worksheet, you can place anywhere in the existing datasheet as we just want to get values from it.

Now in the Grade first row, we will write VLOOKUP function. The syntax of this function is

VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup] )

The first parameter of the formula lookup_value defines the value of the number which we will be looking in the newly created table. We need to lookup the value 80 (Marks field) in the newly created table. The next parameter, table_array defines the table we will be referring to in our case it will be newly created table, containing ranges of marks and grades. col_index_num defines data from which column we want to extract values to show, in our case it is the second column that contain grades range. [range_lookup] lets you to choose an option  either TRUE(approximately matching of values) or FALSE (Exact matching of values).

We will write this function in Grade first row, it will go like this;

=VLOOKUP(C2,$F$3:$G$8,2,TRUE)

In the formula parameters, C2 is cell of column Marks which contain marks secured by students, F3:G8 is the location of the newly created table, containing ranges of marks and grades (use absolute referencing with $ sign), 2 in the formula means that values from second column will appear, and TRUE defines that we need approximately match as we have included ranges not exact values.

After evaluating formula, it will show grade A in Grade column as shown in the screen shot below.
