This is the documentation of JSU for Jira Cloud. If you are using JSU on Jira Server/Data Center, you can find the documentation here.



The 'Regular Expression Check' compares the value of a text, number, or url field against a regular expression. You could verify that the content matches a given format with it.


You must select the field to be checked and enter the regular expression. For example:

  • [0-9]{4}-[0-9]{4} allows numbers such as: 1245-7783
  • [0-9]+ EUR$ allows price tags such as: 34 EUR
  • [a-z]* allows an empty string, or any lower case word such as: yellow
  • Option [A,B] allows a selection of options: Option A, Option B or both.

Detailed Documentation on regular expressions can be found on for a technical documentation, or for a more straightforward description. Another good resource for developing and testing regular expressions is


A workflow is configured so that the 'Create' transition has the 'Regular Expression Check Precondition'. If the summary contains the phrase "Onboarding" or "onboarding", a sub-task will be created for the creation of the user account in the company's systems.
