Regular Expressions

Search patterns for task automation.

While graphic design is often perceived as a purely visual discipline, professional work with layouts and interfaces inevitably involves processing large datasets. Regular expressions—or RegEx—is a specialized language for describing text patterns that significantly expands the capabilities of standard find-and-replace tools.

For instance, Adobe InDesign’s GREP styles (based on RegEx) can automatically handle orphan control by linking prepositions to following words, convert currency symbols to superscripts, or standardize units of measurement. In Figma, support for pattern matching allows you to rename layers and other project elements in seconds.

The true value of regular expressions lies in their ability to turn a chaotic mess of objects into a structured hierarchy based on a predefined rule. Calendar dates, phone numbers, web addresses—these are all strings with a clear structure. For example, the pattern (\d{2})\.(\d{2})\.(\d{4}) describes a date in the DD.MM.YYYY format. To reformat it to YYYY/MM/DD, you simply set the replacement to $3/$2/$1.

While the syntax may seem daunting at first, RegEx is worth mastering at a basic level. It allows you to tackle data processing tasks where manual work would, quite literally, take hours.
