Regular Expression

A Regular Expression is a sequence of characters that forms a search pattern. Regular Expressions are very similar across all programming languages.


  • Action

    The function will always return the index and the length of found matches.

    First match only returns the information for the first match found.

    All matches returns a list of all matches found.

    Replace will use the ‘Replace with’ field to replace content matching the pattern.

    Split will split the string at the matched pattern. The matched pattern is not returned.

    If you are, for example, looking for a comma to split a string (1,2) by, then a list containing two rows is returned. The comma will not be returned.

  • Expression

    The search pattern to apply to the text. See some examples

  • Input string

    The string to apply the pattern to.

  • Options

    A set of standard Regular Expression options to pick from. Here is a detailed description of these options.

  • Replace with

    A string to replace matched content with.

  • Loop results

    A flag to indicate if lists returned by the function should be looped or provided as a ‘list object’.
