List of 12 Best Excel Functions for Data Analysis
1. IF
The IF function is one of the most basic and useful functions in Excel. It allows you to perform conditional logic, which means you can test a condition and return different values based on whether the condition is true or false. For example, you can use the IF function to display “Pass” or “Fail” depending on whether a student’s score is above or below a certain threshold.
The syntax of the IF function is:
=IF(logical_test, value_if_true, value_if_false)
Where:
- logical_test is the condition you want to check, such as A1>60
- value_if_true is the value you want to return if the condition is true, such as “Pass”
- value_if_false is the value you want to return if the condition is false, such as “Fail”
Here is an example of how to use the IF function to display the status of a student based on their score:
!IF function example
As you can see, the IF function checks the score in column B and returns “Pass” if it is greater than or equal to 60, and “Fail” otherwise.
You can also nest multiple IF functions within each other to test more than one condition. For example, you can use the IF function to display the grade of a student based on their score, using the following criteria:
- A if score is greater than or equal to 90
- B if score is greater than or equal to 80 and less than 90
- C if score is greater than or equal to 70 and less than 80
- D if score is greater than or equal to 60 and less than 70
- F if score is less than 60
The nested IF function would look like this:
=IF(B2>=90,“A”,IF(B2>=80,“B”,IF(B2>=70,“C”,IF(B2>=60,“D”,“F”))))
Here is the result of applying the nested IF function to the same data:
!Nested IF function example
As you can see, the nested IF function checks the score in column B and returns the corresponding grade based on the criteria.
The IF function is very useful for data analysis, as it allows you to create custom rules and scenarios for your data. You can use it to classify, categorize, flag, or highlight your data based on certain conditions.
2. SUMIFS
The SUMIFS function is one of the most powerful functions for data analysis. It allows you to sum values that meet multiple criteria. For example, you can use the SUMIFS function to calculate the total sales for a specific product and region, or the total revenue for a specific month and year.
The syntax of the SUMIFS function is:
=SUMIFS(sum_range, criteria_range1, criteria1, criteria_range2, criteria2, …)
Where:
- sum_range is the range of values you want to sum, such as C2:C9
- criteria_range1 is the first range of values you want to apply the criteria to, such as B2:B9
- criteria1 is the first criteria you want to use to filter the values, such as “North”
- criteria_range2, criteria2, … are the additional ranges and criteria you want to use, up to 127 pairs
Here is an example of how to use the SUMIFS function to calculate the total sales for the product “Pencil” in the region “North”:
!SUMIFS function example
As you can see, the SUMIFS function sums the values in column C that match both the criteria in column A and column B, and returns the result in cell E3.
You can also use cell references, wildcards, or operators as criteria in the SUMIFS function. For example, you can use the following criteria to sum the sales for the product entered in cell E2 in the region entered in cell E3:
- criteria_range1: A2:A9
- criteria1: E2
- criteria_range2: B2:B9
- criteria2: E3
Or, you can use the following criteria to sum the sales for the products that start with the letter “P” in any region:
- criteria_range1: A2:A9
- criteria1: “P*”
- criteria_range2: B2:B9
- criteria2: “*”
Or, you can use the following criteria to sum the sales for the products that have a unit price of more than 10 in any region:
- criteria_range1: D2:D9
- criteria1: “>10”
- criteria_range2: B2:B9
- criteria2: “*”
The SUMIFS function is very useful for data analysis, as it allows you to perform complex calculations and aggregations based on multiple conditions. You can use it to analyze your data from different perspectives and dimensions.
3. COUNTIFS
The COUNTIFS function is another essential function for data analysis. It is very similar to the SUMIFS function, except that it counts the number of values that meet multiple criteria, instead of summing them. For example, you can use the COUNTIFS function to count the number of orders that have a status of “Completed” and a value of more than 500.
The syntax of the COUNTIFS function is:
=COUNTIFS(criteria_range1, criteria1, criteria_range2, criteria2, …)
Where:
- criteria_range1, criteria1, criteria_range2, criteria2, … are the same as in the SUMIFS function
Here is an example of how to use the COUNTIFS function to count the number of orders that have a status of “Completed” and a value of more than 500:
!COUNTIFS function example
As you can see, the COUNTIFS function counts the values in column C that match both the criteria in column B and column D, and returns the result in cell E3.
You can also use the same types of criteria as in the SUMIFS function, such as cell references, wildcards, or operators. For example, you can use the following criteria to count the number of orders that have a status entered in cell E2 and a value of more than the amount entered in cell E3:
- criteria_range1: B2:B9
- criteria1: E2
- criteria_range2: C2:C9
- criteria2: “>”&E3
Or, you can use the following criteria to count the number of orders that have a status that contains the word “Pending” and a value of less than or equal to 300:
- criteria_range1: B2:B9
- criteria1: “Pending”
- criteria_range2: C2:C9
- criteria2: “<=300”
Or, you can use the following criteria to count the number of orders that have a status that is not “Cancelled” and a value that is not blank:
- criteria_range1: B2:B9
- criteria1: “<>Cancelled”
- criteria_range2: C2:C9
- criteria2: “<>”
The COUNTIFS function is very useful for data analysis, as it allows you to perform frequency analysis and distribution analysis based on multiple conditions. You can use it to measure the occurrence and proportion of your data based on certain criteria.
4. VLOOKUP
The VLOOKUP function is one of the most popular and widely used functions in Excel. It allows you to look up a value in a table and return a corresponding value from another column. For example, you can use the VLOOKUP function to look up the product name in a table and return the unit price from another column.
The syntax of the VLOOKUP function is:
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Where:
- lookup_value is the value you want to look up, such as “Pen”
- table_array is the range of cells that contains the lookup table, such as A2:D9
- col_index_num is the column number in the table from which you want to return a value, such as 4
- [range_lookup] is an optional argument that specifies whether you want an exact match or an approximate match, such as FALSE for exact match or TRUE for approximate match
Here is an example of how to use the VLOOKUP function to look up the product name in column A and return the unit price from column D:

=INDEX(array, row_num, [column_num])
Where:
- array is the range of cells or table that contains the values, such as A2:D9
- row_num is the row number in the array from which you want to return a value, such as 2
- [column_num] is an optional argument that specifies the column number in the array from which you want to return a value, such as 1
Here is an example of how to use the INDEX function to return the product name from the second row and the first column of the table in A2:D9:
!INDEX function example
As you can see, the INDEX function returns the value “Pen” from the cell A3, which is the second row and the first column of the table.
You can also use the INDEX function to return a range of values, by specifying the starting and ending positions of the rows and columns. For example, you can use the INDEX function to return the range B3:C4 from the table in A2:D9, by using the following syntax:
=INDEX(A2:D9, 2, 2):INDEX(A2:D9, 3, 3)
Here is the result of applying the INDEX function to return the range B3:C4:
!INDEX function range example
As you can see, the INDEX function returns the range B3:C4, which contains the values “North”, “200”, “South”, and “150”.
The INDEX function is very useful for data analysis, as it allows you to access and manipulate specific values or ranges in your data. You can use it to extract, rearrange, or combine data from different sources.

Where:
- lookup_value is the value you want to find, such as “Pencil”
- lookup_array is the range of cells or table that contains the values, such as A2:A9
- [match_type] is an optional argument that specifies how you want to match the value, such as 0 for exact match, 1 for less than or equal to, or -1 for greater than or equal to
Here is an example of how to use the MATCH function to find the row number of the product “Pencil” in the table in A2:D9:
!MATCH function example
As you can see, the MATCH function returns the value 4, which is the row number of the product “Pencil” in the table.
You can also use the MATCH function to find the column number of a value in a range or table, by using the TRANSPOSE function to switch the rows and columns of the range or table. For example, you can use the MATCH function to find the column number of the region “West” in the table in A2:D9, by using the following syntax:
=MATCH(“West”, TRANSPOSE(A2:D9), 0)
Here is the result of applying the MATCH function to find the column number of the region “West” in the table:
!MATCH function column example
As you can see, the MATCH function returns the value 3, which is the column number of the region “West” in the table.
The MATCH function is very useful for data analysis, as it allows you to locate and identify values or ranges in your data. You can use it to compare, validate, or look up data from different sources.
