title: Data in Excel add-in
body: <p>How would I go about extracting data from an Excel sheet into a list in an Excel Add-In? Ideally I would need to get each row from a sheet and save it in a list of tuples in the add-in. </p>
  
  <p>It's a C# add-in and the data will be stored within the add-in in a worksheet. The data doesn't need to be stored from session to session. Any ideas?</p>
