[ID CC2023] change format to batch of equations mathtype

How can I change the format of batch mathtype equations from a directory?
Would you please explain what do you mean by that? What is your present equations' format and what are you're expecting it to be? What are you going to do with these equations and so on. Certainly InDesign can't change any equations' format at all, so there is a little bit misunderstanding down here.
