I use this code to transform an excel-file to csv:
$reader = PHPExcel_IOFactory::createReader('Excel5');
$excel = $reader->load('datei.xls');
$writer = PHPExcel_IOFactory::createWriter($excel, 'CSV');
As long as all values are longer than 1 character it works fine.
If the excel-value is like "U" or "X" the result is "" (empty)
If the excel-value is "F4" or "HL1" the result comes correct as "F4" ...
So what can I do t receive single charater values in csv?
Sorry if this is a stupid question, but I spent already hours in searching for a solution
