Excel Spreadsheet as Data Source & Copying that Data to an Existing SharePoint List

Question

Hello,
I have an Excel spreadsheet that I get daily and cut and paste into an existing SharePoint list. Is there a way to make that Excel spreadsheet a data source and copy the data to an existing SharePoint list with less manual involvement?
Tools at my disposal include: SharePoint 2010 Designer, InfoPath, and Access.
I thought there might be a REST method I could use via InfoPath but I'm not aware of any offhand.
Goal is to have a method to upload/overwrite an Excel file (stored in a SharePoint library), every day, and then automate the process of copy it to a SharePoint list (actually overwriting the old data in the SharePoint list).
Any help would be greatly appreciated.

Hi,
We can create a console application and use C# code to read the data from the Excel file and using SharePoint .Net Client Object Model to add the data into a SharePoint list, then create a windows job to execute the console application.
