title: Access excel data without opening it in application
body: <p>I am looking for a very fast way to process excel files stored on a network location. I need to check certain values in the excel files but my standard method of opening workbook, look for what I need and close is taking way to long for this huge pile of excel files.</p>
  
  <p>Are there other method to access excel content without having to open them?</p>
  
  <p>I have read about EPplus, but are there others?</p>
