Is there any other PHP components like PHPExcel?
There is some class that generates PHP Excel files (real excel files, not that .csv thing). I use (DEPRICATED) See edit 2:

BUT: I have had a problem when trying to read these generated excel files with the java excel READER, so there might be bugs in this PHP script.
EDIT: Nice one: http://www.phpclasses.org/package/2037-PHP-Generate-spreadsheet-files-Excel-xls-XML-format.html
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.). https://github.com/PHPOffice/PhpSpreadsheet
