How to update Visual Studio project files from Azure server

I have an ASP.NET MVC5 website being hosted for free in Azure.

In my Visual Studio project solution there are some CSV files I use for data storage(instead of a SQL Server database to keep the website free) and these files are modified by users.

How do I update my local files with the files in the Azure server. Or better yet, how do I get any changes made in the Azure server to my local Visual Studio solution.
