Transfer data via cvs

Hello everyone, I have developed a CRM application that enables users to store their customers’ information, such as their names and addresses. Some users who already have their own customer databases may need to transfer their data to my app, and I’m wondering how this can be accomplished. If a user has a CSV file containing their data, is it a simple process to upload it to my app?

yes, there are workflows for upload CSV…there are also free plugins that help
