The easier way will be exporting the .xls to a .csv or .xml format, and
yes, is doable very easy, But not with js, is done server sided, PHP or
ASP or Perl can do all that on the server, preprocess it, and Then, serve
the ouput HTML file to the client, quite often done with many records of
all types, I think you can do it directly to an .xls through SQL ODBC
object accessing in PHP or ASP, but is done on the server.
