require('php-excel-reader/excel_reader2.php');
require('SpreadsheetReader.php');
try
{
$Spreadsheet = new SpreadsheetReader($Filepath);
/* for reading only first sheet */
/*
   foreach ($Spreadsheet as $Row)
   {
       print_r($Row);
   }*/
   /* for reading all first sheet or reading specific sheet */
$Sheets = $Spreadsheet -> Sheets();
foreach ($Sheets as $Index => $Name)
{
echo '*** Sheet '.$Name.' ***'.PHP_EOL;
$Spreadsheet -> ChangeSheet($Index);
foreach ($Spreadsheet as $Key => $Row)
