Please advice, I am new to postman. I am trying to export postman xml file into sql. where do I start from? Any documentation/video will be helpful
Welcome to the Postman Community 
I’m not entirely sure what you’re referring too here? Has the XML file been created from Postman via a Collection Run with the Postman CLI or Newman?
Postman wouldn’t be able to convert anything to SQL.
Can you expand on the information here and provide more information, please?
