title: Read earth coordinates from an excel file, and draw markers in a map
body: <p>I have an excell file with a column with earth coordinates inside Spain.I want to create a script or application that reads that data, and put a marker in a map of Spain, how can I generate those markers in a map? I don't need details, but just abstract information.</p>
  
  <p>Should I create a macro maybe? Should I use google maps?</p>
