Tentang Format XLS
XLS adalah format spreadsheet lama yang digunakan oleh Microsoft Excel dari versi 97 hingga 2003. XLS menyimpan data dalam Binary Interchange File Format (BIFF), struktur biner eksklusif yang mengkodekan nilai sel, rumus, pemformatan, bagan, dan makro. File XLS dibatasi hingga 65.536 baris dan 256 kolom per lembar kerja dibandingkan dengan lebih dari satu juta baris di XLSX modern.
Meskipun digantikan oleh XLSX, file XLS tetap umum di sistem perusahaan lama, lembaga pemerintah, dan data bisnis yang diarsipkan. Formatnya mendukung makro VBA, objek yang disematkan, dan beberapa lembar kerja. File XLS dapat dibuka di Excel modern, Google Sheets, LibreOffice Calc, dan sebagian besar aplikasi spreadsheet, meskipun disarankan untuk mengonversi ke XLSX untuk kinerja yang lebih baik, kapasitas data yang lebih besar, dan keamanan yang lebih baik.
