Variable Transformation

Shared by Ines • February 09, 2026

It is now possible to modify existing variables during test execution using natural language, super handy to clean, reformat, combine, or reuse data without re-extracting or regenerating anything

Examples

  • Remove leading zeroes from [PHONE]
  • Convert [USERNAME] to lowercase
  • Copy [TOKEN] into [AUTH_TOKEN]
  • Extract domain from [URL] and store in [DOMAIN]
  • Combine [FIRST_NAME] and [LAST_NAME] into [FIRST_NAME]
  • Subtract [DISCOUNT] percent from [PRICE] and store in [PRICE]

The extract web action work exactly like before, it always retrieves the full text from the page.

If you need to adapt or clean the value, you must add a separate transform step.
