Welcome to “Mastering Essential Excel Functions for Operators,” your comprehensive guide to Excel proficiency. In this course, we’ll cover a range of functions, from the basics to advanced techniques, designed specifically for operators like you. Follow these instructions to get the most out of your learning experience:

Excel Functions Covered:

[PART 1]

  1. LEN Function: Calculating the number of characters in a cell.
  2. FIND Function: Checking if a specific word is present in a cell.
  3. VLOOKUP Function: Retrieving information about a specific company.
  4. MIN/MAX Functions: Finding the minimum and maximum sales across all companies.

[PART 2]

  1. MAXIFS/MINIFS Functions: Determining the maximum and minimum sales per country.
  2. SUMIFS Function: Calculating the total sales for companies that meet specific criteria.
  3. AVERAGEIFS Function: Computing the average sales for companies meeting multiple conditions.

Data Visualization: After mastering these functions, we’ll demonstrate how to visually represent the processed data with three essential charts:

In this lesson, we will explore the LEN function in Excel, which is used to calculate the number of characters in a cell or a text string.

LEN Function Overview:

The LEN function returns the number of characters in a given text string. Let’s see how it works:



Practical Application:

Now, let’s apply the LEN function to assess the length of company names. If the name has more than 5 characters, we want to label it with “O” for “Yes”; otherwise, label it with “X” for “No.” In cell R2 of your Excel sheet, input the following formula: =IF(LEN(A2)>5,”O”,”X”)

If len

This formula checks if the length of the company name in cell A2 is greater than 5. If true, it outputs “O”; otherwise, it outputs “X.” After entering the formula in cell R2, use the autofill feature to apply the formula to the rest of the cells in the column. Feel free to experiment with different company names and lengths to see how the formula responds. This practical application will help you understand and use the LEN function effectively.

  • For companies with names like “ABC Inc.,” “XYZ Corporation,” “LMN Corp” and “PQR Industries” (with more than 5 characters), the label is “O.”
  • For companies with names like “UVW” (with 5 characters or fewer), the label is “X.”

This is based on the application of the LEN function and the accompanying IF statement, as explained in the provided formula. You can adapt this example to your actual dataset in Excel.

FIND Function Overview

Let’s continue with the example dataset and add more columns to showcase the FIND function and the use of IF and ISERROR functions. We’ll consider column F to demonstrate how to classify companies as “Motor” or “Non-Motor” based on whether the company name contains the word “Motor.”

The FIND function in Excel is used to locate the position of a specific substring within a text string. Here’s an overview of the  FIND  function:

FIND(find_text, within_text, [start_num])

Practical Application:

Let’s say you have a list of company names in column A, and you want to check if the word “Corp” is present in each company name. You can use the FIND function along with IF and ISERROR to classify the companies.



  • If the word “Corp” is present in cell A2, and if it is, the result should be “Yes.” Your formula looks correct.
  • It uses the FIND function to check for the presence of “Corp” in cell A2.
  • If “Corp” is found, it returns “Yes”; otherwise, it returns an empty string (“”). The ISERROR function is used to handle the case when “Corp” is not found, preventing an error.

VLOOKUP Function Overview

The VLOOKUP function in Excel is a powerful tool for looking up values in a table based on specified criteria. Here’s an overview of how the VLOOKUP function works:

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

Practical Application:


  • H4: This is the value you want to find in the first column of the table (A2:A7) – Company Name you want to look up
  • A2:C7 : This is the range of your table where Excel should look for the information. – Company Name range
  • 3 : This is the column index number. In this case, it’s the third column of the table (C) from which you want to retrieve the information.
  • 0 : This indicates that you want an exact match.


MAX/MIN Function Overview

To calculate the maximum and minimum revenue for each country using MAX and MIN functions.

For Maximum Sales


  • The formula =MAX(D2:D7) in Excel calculates the maximum value in the range of cells D2 to D7. It identifies the highest revenue among the listed companies in the specified range.

For Minimum Sales


  • The formula =MIN(D2:D7) in Excel calculates the minimum value in the range of cells D2 to D7. It identifies the lowest revenue among the listed companies in the specified range.
