PHPExcel for, you guessed it, PHP. An order of magnitude less hassle than CSV ("the files you generate are wrong, but only on some computers! Fixitfixitfixit!!!"), and surprisingly powerful.

Note: Last time we used it for large data report generation results were slow and consumed huge amount of memory.

Depends on the amount of data, calculations, and formatting. For "output this array of arrays as XLSX instead of CSV", I find its current performance acceptable.
