Excel for Dummies – Using Regular Expressions with XLOOKUP

Excel for Dummies has recently introduced “Regular Expressions.” Another name for this function is regex. These are powerful search patterns used to match and process text. Excel, according to its developers, presents this aging innovation as “highly advanced search functions,” writes https://xrust.ru/. They are capable of searching for complex character strings based on patterns, not just exact matches. Regular expressions allow you to find text that matches a specific pattern, for example, all words starting with a vowel (e.g., “^[AEIOUaeiou]”) or any number consisting of exactly five digits (e.g., “^\d5$”). These patterns help make searches more flexible and efficient, especially when working with large datasets. Thematic books cover the XLOOKUP function and describe its arguments in detail. However, regular expressions are so new that they have not yet made it into the printed versions of many books.

To use a regular expression with XLOOKUP, you need to specify the regular expression pattern in the lookup value argument and set the match type argument to 3. For example, suppose you have an Excel table named Data, and you want to return the total sales for the first vendor whose name contains the word “Fruit.” Below is the formula that will perform the search:

`=XLOOKUP(“\bFruit\b”, Data[Vendor], Data[Total Sales], ,3)`
