How can Regular Expressions (Regex) be used in Microsoft applications?

In Microsoft applications like Excel, Word, and PowerShell, Regular Expressions (Regex) are used to search, match, and manipulate text. In Excel, you can use Regex through VBA (Visual Basic for Applications) or external add-ins to find patterns in data. In Word, Regex is utilized in the Find and Replace feature, enabling complex text searches. PowerShell supports Regex directly with cmdlets like Select-String and -match, allowing text filtering and manipulation. Regex in Microsoft tools is essential for tasks like validation, extracting specific text patterns, and automating text-based workflows, improving efficiency in data processing and reporting.
