Better ways of incorporating data into soap ui

Hi,
I am working on an eligibility engine project and I have created a excel file incorporating all the rules. I am populating that excel and importing it into soap UI and checking for request and response. The problem I am facing is with the excel, since the amount of data I am putting in excel is so big, sometimes the formulas are crashing. What is the best way to incorporate these data into soap ui without using excel.

Thank you.
