Microsoft Excel remains a powerful tool for data analysis and manipulation, and staying up-to-date with the latest formulas is crucial for maximizing your productivity and improving your spreadsheets. This guide with the help of Kenji Explains covers five essential categories of Excel formulas: math, date, text, logic, and lookup functions. With each section providing practical examples and clear explanations to help you understand and apply these formulas effectively in your work. To see the formal is in action check out the audio currently created by Kenji Explains.
Math Functions
The AGGREGATE function is a versatile tool that handles operations like SUM and AVERAGE while ignoring errors. This is particularly useful when working with large datasets that may contain hidden rows or errors. For example, `=AGGREGATE(9, 5, A1:A10)` allows you to sum a range while ignoring any potential issues.
When you need to generate random numbers within specified ranges, the RANDARRAY function comes in handy. This formula is ideal for creating random samples or simulating data. For instance, `=RANDARRAY(5, 1, 1, 100, TRUE)` generates five random integers between 1 and 100, providing a quick way to populate cells with test data.
Date Functions
Calculating the difference between two dates is a common task in many projects. The DATEDIF function simplifies this process by allowing you to determine the difference in days, months, or years. For example, `=DATEDIF(A1, B1, “Y”)` gives you the number of years between two dates, which is useful for age calculations or project timelines.
When precision is key, the YEARFRAC function provides accurate year differences, taking into account leap years. This formula is particularly valuable for financial calculations. By using `=YEARFRAC(A1, B1)`, you can calculate the exact fraction of the year between two dates.
Project managers will appreciate the NETWORKDAYS function, which calculates the number of working days between two dates, excluding weekends and holidays. By incorporating `=NETWORKDAYS(A1, B1, holidays)` into your spreadsheets, you can easily determine the available working days for a given time period.

Text Functions
Combining text from multiple cells is a breeze with the TEXTJOIN function. By specifying a delimiter, you can create lists or concatenate data effortlessly. For example, `=TEXTJOIN(“, “, TRUE, A1:A5)` combines the text from cells A1 to A5, separating each item with a comma.
When you need to split text into columns based on a specific delimiter, the TEXTSPLIT function is your go-to solution. This formula is particularly handy for parsing data from external sources. By using `=TEXTSPLIT(A1, “,”)`, you can quickly split the text in cell A1 into separate columns wherever a comma is found.
Data cleanliness is essential for accurate analysis, and the TRIM function helps you achieve just that. By removing extra spaces from text, including leading, trailing, and multiple spaces between words, `=TRIM(A1)` ensures that your data is consistent and ready for further processing.
Formatting names or titles is a snap with the PROPER function. This formula capitalizes the first letter of each word, giving your data a professional touch. For instance, `=PROPER(A1)` converts “john doe” to “John Doe” instantly.
Logic Functions
The IF function is a fundamental tool for decision-making processes in Excel. It allows you to perform logical tests and return values based on specified conditions. For example, `=IF(A1 > 10, “High”, “Low”)` returns “High” if the value in cell A1 is greater than 10, and “Low” otherwise.
When you need to combine multiple conditions that must all be true, the AND function is your ally. This formula is useful for complex logical tests. For instance, `=AND(A1 > 10, B1 < 5)` returns TRUE only if both conditions are met.
In situations where you want to combine multiple conditions and return TRUE if at least one of them is met, the OR function comes into play. This formula provides flexibility in your criteria. For example, `=OR(A1 > 10, B1 < 5)` returns TRUE if either condition is satisfied.
Lookup Functions
Consolidating data from different sources is made easy with the VSTACK function. This formula merges multiple tables into one, streamlining your data management process. For instance, `=VSTACK(A1:B5, C1:D5)` stacks two ranges vertically, creating a single, unified table.
The GROUPBY function is a powerful alternative to pivot tables, allowing you to sum values by specified categories. This formula is invaluable for summarizing data quickly and efficiently. By using `=GROUPBY(A1:B10, A1:A10, “Sum”)`, you can group and sum data based on categories defined in your spreadsheet.
When you need to create a matrix of summarized data by rows and columns, the PIVOTBY function is your go-to solution. This formula is essential for in-depth data analysis, providing a clear overview of your information. For example, `=PIVOTBY(A1:C10, “Rows”, “Columns”, “Values”)` creates a pivot table-like summary, allowing you to explore your data from different angles.
- Master these essential Excel formulas to boost your productivity and data handling capabilities.
- Use math functions like AGGREGATE and RANDARRAY to handle complex calculations and generate test data.
- Simplify date calculations with DATEDIF, YEARFRAC, and NETWORKDAYS for accurate project planning.
- Streamline text manipulation using TEXTJOIN, TEXTSPLIT, TRIM, and PROPER for data consistency.
- Implement logical tests and decision-making processes with IF, AND, and OR functions.
- Consolidate and summarize data efficiently using VSTACK, GROUPBY, and PIVOTBY for comprehensive analysis.
By incorporating these Excel formulas into your workflow, you’ll be well-equipped to tackle a wide range of data manipulation and analysis tasks. This structured approach to learning and applying these formulas will enhance your proficiency and help you make the most of Excel’s powerful features in 2024 and beyond.
