2021 Microsoft Excel Formulas and Functions: Unleash Powerful Excel Productivity Tips

by

Microsoft Excel is one of the most widely used tools for data analysis, business reporting, and automation. Excel has consistently evolved to meet the needs of both novice and expert users, offering built-in formulas and functions that streamline tasks and enhance productivity. In this article, we will explore how to leverage powerful Excel formulas and functions and Excel productivity tips, especially those introduced in or updated for the 2021 version. Whether you’re an Excel power user or a beginner aiming to maximize your efficiency, this guide will help you understand how to use Excel to its full potential.

What Are Excel Formulas and Functions?

In Excel, a formula is an expression that operates on values in a range of cells or a cell, whereas a function is a predefined formula that simplifies complex calculations. Functions are stored in the Excel library and are designed to perform specific tasks such as summing data, finding averages, or determining financial rates.

For example, a formula could be as simple as:

=A1 + B1

But with functions, you can achieve more advanced operations like:

=SUM(A1:A10)

Now, let’s explore how to use some of Excel’s most powerful built-in formulas and functions effectively.

Key Excel Formulas and Functions You Should Know

Let’s dive into some of the most important Excel formulas and functions you can use in 2021, categorized by their use cases.

1. Excel Mathematical Functions

One of the most frequent uses of Excel is to perform mathematical calculations. Excel offers a wide array of built-in mathematical functions, but the following are particularly useful:

  • SUM(): Adds all numbers in a range of cells.
    • Example: =SUM(A1:A5)
  • AVERAGE(): Calculates the average of a group of numbers.
    • Example: =AVERAGE(B1:B10)
  • MIN() and MAX(): These functions return the minimum and maximum values in a set of data, respectively.
    • Example: =MIN(C1:C100) and =MAX(D1:D50)
  • ROUND(): Rounds a number to a specified number of digits.
    • Example: =ROUND(E1, 2) (rounds E1 to two decimal places)

In 2021, Microsoft Excel continued to enhance calculation performance, making these functions even faster when processing large datasets. For financial analysts, using the ROUND() function is especially important when presenting figures, as it ensures data is presented professionally without overwhelming your audience with unnecessary decimal places.

2. Text Functions in Excel

Excel’s text functions are essential for cleaning data and performing various text manipulation tasks. In 2021, text processing remains critical for users who work with raw data from multiple sources.

  • CONCAT(): Combines the text from multiple cells into one.
    • Example: =CONCAT(A1, ” “, B1) (combines A1 and B1 with a space in between)
  • TEXT(): Converts a value to text in a specific number format.
    • Example: =TEXT(A1, “dd-mm-yyyy”) (converts date to the format day-month-year)
  • LEFT(), RIGHT(), and MID(): These functions are used to extract a substring from text.
    • Example: =LEFT(A1, 5) (extracts the first 5 characters from the left of A1)
  • LEN(): Returns the number of characters in a text string.
    • Example: =LEN(B1) (counts the number of characters in B1)

These functions are vital in situations where you’re dealing with messy data that needs formatting or analysis.

3. Excel Logical Functions

Logical functions allow you to build more dynamic and complex formulas. They perform tests and return values based on whether certain conditions are met. The most commonly used logical functions include:

  • IF(): Tests whether a condition is true or false and returns a specified value.
    • Example: =IF(A1>10, “Yes”, “No”) (returns “Yes” if A1 is greater than 10, otherwise “No”)
  • AND() and OR(): These functions check multiple conditions.
    • Example: =AND(A1>10, B1<20) (returns TRUE if both conditions are true)
  • IFERROR(): Returns a value you specify if a formula results in an error.
    • Example: =IFERROR(A1/B1, “Division Error”)

Excel 2021 has improved how it handles large datasets, making logical functions faster and more efficient, especially when used in data models.

4. Excel Lookup and Reference Functions

Data lookup is an essential task for many Excel users, and Excel offers robust functions for this purpose. In 2021, Excel made significant strides in improving lookup functions, including the introduction of dynamic arrays in previous years, which still offer enhanced functionality today.

  • VLOOKUP(): Searches for a value in the first column of a range and returns a value in the same row from another column.
    • Example: =VLOOKUP(A1, B1:C10, 2, FALSE)
  • HLOOKUP(): Similar to VLOOKUP, but searches for values horizontally.
    • Example: =HLOOKUP(A1, B1:D4, 3, FALSE)
  • XLOOKUP(): The 2021 version of Excel includes XLOOKUP, a more versatile function that allows for both horizontal and vertical lookups, making it more powerful than its predecessors.
    • Example: =XLOOKUP(A1, B1:B100, C1:C100)
  • MATCH() and INDEX(): These functions are often used together to perform more flexible lookups.
    • Example: =INDEX(C1:C10, MATCH(A1, B1:B10, 0))

The XLOOKUP function is a game-changer in 2021, as it addresses many limitations of older lookup functions, such as handling searches in either direction and eliminating the need for a sorted lookup table.

5. Excel Financial Functions

For professionals in accounting and finance, Excel’s built-in financial functions are indispensable. Some key functions include:

  • NPV(): Calculates the Net Present Value of an investment based on a series of periodic cash flows and a discount rate.
    • Example: =NPV(0.1, A1:A5)
  • IRR(): Returns the Internal Rate of Return for a series of cash flows.
    • Example: =IRR(A1:A10)
  • PMT(): Calculates the payment for a loan based on constant payments and a constant interest rate.
    • Example: =PMT(5%/12, 60, -10000) (calculates monthly payments for a $10,000 loan over 60 months at 5% annual interest)

6. Excel Date and Time Functions

Excel offers robust functions for handling dates and times, and these are essential for any project that involves scheduling or time tracking:

  • TODAY() and NOW(): Returns the current date and date/time, respectively.
    • Example: =TODAY() and =NOW()
  • DATE(): Combines individual year, month, and day values to create a date.
    • Example: =DATE(2021, 12, 25) (returns December 25, 2021)
  • NETWORKDAYS(): Returns the number of working days between two dates.
    • Example: =NETWORKDAYS(A1, B1)

For users managing time-sensitive projects, these functions can greatly improve tracking and scheduling capabilities.

How to Maximize Your Use of Excel Formulas and Functions

To get the most out of Excel’s functions and formulas, follow these best practices:

  1. Understand the Data: Before applying functions, ensure you understand the dataset you’re working with. This helps you choose the appropriate function.
  2. Combine Functions: Excel’s true power is in combining multiple functions. For example, use IF() with VLOOKUP() to create more advanced lookup formulas that return different values based on conditions.
  3. Leverage Named Ranges: Naming your data ranges can make your formulas easier to read and less prone to errors. For example, instead of =SUM(A1:A10), you can name the range “Sales” and use =SUM(Sales).
  4. Use Excel Tables: Converting a range of data into an Excel Table not only makes your worksheet cleaner but also allows Excel to dynamically update ranges when new data is added.
  5. Master Shortcuts: Excel’s keyboard shortcuts can significantly speed up your workflow. For example, Ctrl + Shift + L applies or removes filters, and F2 allows you to quickly edit a cell.
  6. Practice with Real-World Data: The more you practice using Excel’s built-in functions on real-world projects, the more proficient you’ll become. Start by automating simple tasks and then move on to more complex formulas.

Conclusion

Mastering Excel’s built-in formulas and functions can drastically improve your productivity, help you make informed decisions, and simplify even the most complex calculations. From financial analysis to data cleaning and logical operations, Excel 2021 provides an array of powerful tools that can be combined to solve various business challenges. By learning how to apply these functions effectively, you’ll unlock the full potential of Excel and elevate your data management and analytical skills.
