Hi Snehal,
You can use the Excel Importer (https://marketplace.mendix.com/link/component/726) who works with Excel files and CSV files, or the CSV Importer module (https://marketplace.mendix.com/link/component/108605) to achieve this.
With this module you can define an import template that allows you to map the data in your csv file to entities + attributes in your mendix domain module.
Good luck!
