Question

i have found this answer ,
PHP Converting CSV to XLS - phpExcel error
but i have tried it in Laravel 4 and i am not able to get it to work , any help would be appreciated.
My Code
public function CsvExcelConverter($filename){
$objReader = Excel::createReader('CSV');
$objReader->setDelimiter(";");
$objPHPExcel = $objReader->load('uploads/'.$filename);
$objWriter = Excel::createWriter($objPHPExcel, 'Excel5');
//new file
$new_filename = explode('.',$filename);
$new_name = $new_filename[1];
$objWriter->save($new_name.'.xls');
return $new_name.'.xls';
}

Answer 1

thank for the answers, but for some reason we cant seem to set the delimiter on load but i have found that you can set it in the config file .
vendeor/maatwebsite/excel/src/config/csv.php
then just specify the delimiter. this way when loading the file it actually separates each entry and when converting it each entry is in its own cell.
thanks for all the help.

/* Get the excel.php class here: http://www.phpclasses.org/browse/package/1919.html */
require_once("../classes/excel.php");
$inputFile=$argv[1];
$xlsFile=$argv[2];
if( empty($inputFile) || empty($xlsFile) ) {
die("Usage: ". basename($argv[0]) . " in.csv out.xls\n" );
}
$fh = fopen( $inputFile, "r" );
if( !is_resource($fh) ) {
die("Error opening $inputFile\n" );
}
/* Assuming that first line is column headings */
if( ($columns = fgetcsv($fh, 1024, "\t")) == false ) {
print( "Error, couldn't get header row\n" );
exit(-2);
}
$numColumns = count($columns);
/* Now read each of the rows, and construct a
big Array that holds the data to be Excel-ified: */
$xlsArray = array();
$xlsArray[] = $columns;
while( ($rows = fgetcsv($fh, 1024, "\t")) != FALSE ) {
$rowArray = array();
for( $i=0; $i<$numColumns;$i++ ) {
$key = $columns[$i];
$val = $rows[$i];
$rowArray["$key"] = $val;
}
$xlsArray[] = $rowArray;
unset($rowArray);
}
fclose($fh);
/* Now let the excel class work its magic. excel.php
has registered a stream wrapper for "xlsfile:/"
and that's what triggers its 'magic': */
$xlsFile = "xlsfile://".$xlsFile;
$fOut = fopen( $xlsFile, "wb" );
if( !is_resource($fOut) ) {
die( "Error opening $xlsFile\n" );
}
fwrite($fOut, serialize($xlsArray));
fclose($fOut);
exit(0);

If you use the maatwebsite/excel library in Laravel, you can only use native PHPExcel instance methods, not static methods. To convert from CSV to excel, this code can be found at Documentation page
Excel::load($filename, function($file) {
// modify file content
})->setFileName($new_name)->store('xls');

In theory, you should create your custom class to set delimiter:
class CSVExcel extends Excel {
protected $delimiter = ';';
}
and now you could use:
CSVExcel::load('csvfilename.csv')->setFileName('newfilename')->export('xls');
But the problem is, that $delimiter isn't used in this case. Delimiter support seems to be added not long time ago, so maybe there is a bug or it needs to be used in the other way. I've added issue just in case for that: https://github.com/Maatwebsite/Laravel-Excel/issues/262
