Excel test data in jenkins

I execute my test suites with parameterized variables from an excel sheet, that is in the project folder.
When executing the suites in Jenkins the excel file ofc can’t be found by the path that was used usually. (C:\Prj\dat1\… for example)

How can you achieve that the test data is still found, or is there another solution?

I dont want to use internal data, I want others to be able to adjust the variables of the file without having to open the whole project. Also the data in convert to excel, which was the most compatible way for now.

use relative path in definition and place file in project folder so it can be pulled from git
