Microsoft Excel has long been a go-to tool for professionals across various industries, offering a wide range of features and functions to streamline data analysis and reporting. With the introduction of new formulas, Excel has become even more powerful, allowing users to tackle complex tasks with ease. In this guide, we’ll explore five innovative Excel formulas: CHOOSECOLS, TEXTSPLIT, TEXTJOIN, REGEX, and GROUPBY, along with AI-powered functions and the versatile DATEDIF function. By mastering these formulas, you’ll be able to enhance your spreadsheets, boost productivity, and make data-driven decisions with confidence.
Excel Formulas
Simplifying Column Selection with CHOOSECOLS
The CHOOSECOLS formula is a catalyst when it comes to selecting specific columns from a table. This formula allows you to streamline your data analysis process by quickly and easily extracting the data you need. By combining CHOOSECOLS with other functions like SORT and TAKE, you can organize and limit your data efficiently, saving valuable time and effort.
Consider this scenario: you have a large dataset containing customer information, including names, addresses, phone numbers, and email addresses. However, for your current analysis, you only need the customer names and email addresses. With CHOOSECOLS, you can:
- Specify the table range containing your data
- Indicate the column numbers or names you want to select (e.g., 1 and 4 for names and email addresses)
- Instantly extract the desired columns into a new table or range
By eliminating the need to manually copy and paste columns, CHOOSECOLS simplifies the process of working with specific subsets of your data.

Mastering Text Manipulation with TEXTSPLIT and TEXTJOIN
Text manipulation is a common task in Excel, and the TEXTSPLIT and TEXTJOIN formulas make it easier than ever to split and combine text data.
TEXTSPLIT is a powerful tool for separating text into columns based on specified delimiters. This is particularly useful when working with data from CSV files or when you need to separate names and addresses into individual components. For example, if you have a column containing full names in the format “LastName, FirstName,” you can use TEXTSPLIT to:
- Specify the cell or range containing the full names
- Indicate the delimiter (in this case, a comma)
- Split the names into separate columns for last name and first name
On the other hand, TEXTJOIN allows you to combine data from multiple columns into a single text string with specified separators. This is particularly handy when creating concatenated lists or merging data from different sources. For instance, if you have separate columns for first name, last name, and email address, you can use TEXTJOIN to:
- Specify the desired separator (e.g., a semicolon)
- Indicate the range containing the columns you want to join
- Create a single text string with the combined data (e.g., “FirstName LastName; Email”)
By leveraging TEXTSPLIT and TEXTJOIN, you can efficiently manipulate text data, saving time and reducing the risk of errors associated with manual data entry.
Unlocking the Power of Pattern Matching with REGEX
Regular expressions, or REGEX, bring the power of advanced pattern matching to Excel. With REGEX functions, you can find and extract complex data patterns, making it easier to validate and analyze your data.
One common use case for REGEX is password validation. If you need to ensure that a column of passwords meets specific criteria (e.g., at least one uppercase letter, one number, and one special character), REGEX can automate this process. You can:
- Define the pattern for a valid password using REGEX syntax
- Apply the REGEX formula to the column containing the passwords
- Instantly identify which passwords meet the criteria and which ones need to be updated
REGEX is also invaluable for extracting specific data from text strings, such as email addresses or phone numbers. By defining the appropriate REGEX pattern, you can quickly isolate and extract the desired information, streamlining your data analysis process.
Streamlining Data Aggregation with GROUPBY
The GROUPBY function is a powerful tool for summarizing and analyzing large datasets. With GROUPBY, you can quickly group data based on specified criteria and perform aggregate functions like SUM, AVERAGE, or COUNT on the resulting groups.
Imagine you have a large dataset containing sales data for multiple regions and product categories. With GROUPBY, you can:
- Specify the columns to group by (e.g., region and product category)
- Indicate the aggregate function to apply (e.g., SUM of sales)
- Create a summary table showing total sales for each unique combination of region and product category
GROUPBY also allows you to customize the output by including headers and removing totals, making it easy to create professional-looking reports tailored to your specific needs.
Harnessing the Power of AI with Advanced Functions
AI-powered functions, such as those provided by the ChatGPT add-in, take Excel’s data extraction capabilities to new heights. These functions leverage artificial intelligence to identify and extract key information from text data, such as:
- Identifying countries and continents mentioned in a text string
- Extracting email addresses or phone numbers from unstructured data
- Categorizing customer feedback based on sentiment or topic
By incorporating AI-powered functions into your Excel workflow, you can automate complex data extraction tasks, saving time and increasing accuracy. This is particularly valuable when dealing with large volumes of unstructured data, such as customer reviews or social media posts.
Calculating Date Differences with DATEDIF
The DATEDIF function is a versatile tool for calculating the difference between two dates in days, months, or years. This function is particularly useful for:
- Tracking project timelines and calculating the duration between milestones
- Determining employee tenure or the length of service
- Calculating the age of an asset or the time since a specific event
For example, if you need to calculate the number of days between a project start date and end date, DATEDIF provides a simple and accurate solution. By specifying the start date, end date, and the desired unit of measurement (e.g., “D” for days), you can quickly determine the duration of the project.
The new Excel formulas discussed in this guide—CHOOSECOLS, TEXTSPLIT, TEXTJOIN, REGEX, GROUPBY, and AI-powered functions—along with the DATEDIF function, provide a powerful toolkit for enhancing your spreadsheet functionality. By mastering these formulas and incorporating them into your workflow, you can streamline data analysis, improve data manipulation, and boost overall productivity.
Whether you’re a data analyst, project manager, or business professional, these advanced Excel techniques will help you make the most of your data, driving better insights and more informed decisions. By leveraging the power of these formulas, you’ll be able to tackle complex tasks with ease, saving time and increasing the impact of your work.
