where do you store your test data

It is PO's responsibility to provide test data.
    However in some instances, especially in negative test scenario
    I may need to generate test data.
    I use java faker to generate data
	How => Faker faker=new Faker();
    or String manupilation(substring concatination etc.)
	I store it  at SharePoint. Saved in my project
    in xls type under data package
