title: Change decimal and thousands separators in excel using Apache POI
body: <p>Does anyone know if using apache-poi library you can change the decimal and thousands separators for Microsoft Excel? </p>
  
  <p>I need to export in excel some data from an web application, and the numbers are formatted depending on some the user's settings. so when the data is exported the numbers should look exactly how they are in the application's page.</p>
  
  <p>Thanks</p>
