How to Intergarte Google maps with custom posts

I am using Types plugin for creating custom posts named preschools. The custom fields right now include address, contact number, photos etc. specific to preschool. Please let me know how I can add Google map to each preschool. Right now I import the data of preschools from csv file. Can I add longitude and latitude of map for each post in excel and import the complete data of a preschool post to wordpress database?
