Prepare: Creating Custom Transformations Using Regular Expressions

When creating custom transformations, one option is to create a Find and Replace transformation. This transformation will "find" or look for certain elements in the report answers and replace them with another value that you specify. 

To create a more accurate Find and Replace custom transformation, you may want to consider using Regular Expressions.

A regular expression (regex or regexp for short) is a special text string for describing a search pattern. You can think of regular expressions as wildcards on steroids.

Simply input the regular expression into the Find column and click on the checkbox to "search using regex (less common)." 

For more detailed information about regular expressions, we recommend visiting this external guide. 

Although the modal will validate whether or not the regular expression is valid, we still recommend testing your regular expression in a regex tester tool such as RegEx Pal.
