Whether it is the customer database, client database, employee database, SharePoint can help you with everything as it comes with unlimited space and provides you with easy access anytime you want.

In Access, you can export data from Access in various formats such as Excel, Word, and SharePoint list. Exporting an Access database to Excel will export an object to a worksheet in an Excel file.

You say you want it into Access because Access is a database, SharePoint already uses a SQL database, so it is technically already in a database.
