Recently brought my php_excel extension back to life. Native C extension for Excel in PHP wrapping LibXL.
2.0 syncs with current LibXL, adds PHP 8.3+ support, 6 new classes (rich text, conditional formatting, form controls, tables, core properties), full typed arginfo, and an actual CI/CD pipeline.
Still 9-10x faster than PhpSpreadsheet, with lower memory use.
