Regular Expression Precondition

This is the JSU for Jira Cloud documentation. If you are using JSU on Jira Server or Data Center, see our Server/Data Center documentation.


The Regular Expression precondition compares the value of a text, number, or URL field against a regular expression. Use it to verify that the content matches a specified format.


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

Example of the Regular Expression precondition as described on this page.
  • [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 in Oracle's documentation for a technical documentation, or at 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.
