Hi @Dixan Thomas,
It is not supported to apply two data validation on one cell. As a workaround, you can create a cascading dropdown list in Excel. Froe example, when A1="open", choices "yes" and "no" are available in another cell; when A1="closed", no choice is available in that cell. Take a reference to this article to create a cascading dropdown list: Make a dependent (cascading) drop down list in Excel.
Please let me know if you still have any question.
