Kisahnya

BAGAIMANA XLS
TERCIPTA.

1985

1987

2007

Excel 2.0 for Windows shipped in 1987 with .xls as its native binary format. An earlier Excel 1.0 had launched on Mac in 1985, but the Windows version’s timing — just ahead of the Windows 3.0 explosion — made Excel the spreadsheet that ate Lotus 1-2-3. By the mid-1990s Excel had roughly 90% market share and .xls had become the universal grammar of financial modelling.

Like .doc, .xls converted in Excel 97 to the OLE Compound File container. And like .doc, it was replaced by a ZIP+XML successor (.xlsx) in Office 2007. For two decades .xls was the file every accountant, banker, and analyst spent their career in. You still find .xls attached to emails from long-established businesses, regulators, and older government portals.

FAKTA UNIK &
TRIVIA.

Excel 97 raised the row limit from 16 384 to 65 536; Excel 2007 (XLSX) exploded it to 1 048 576.

The famous "VLOOKUP" function first appeared in Excel 2.0 in 1987 and has not changed its argument order in 38 years.

Early Excel files could contain executable macros in XLM (pre-VBA) — a format attackers still use for malware because antivirus tools often miss it.

Every .xls file contains a hidden stream called "Workbook" that holds the actual cells; metadata lives in separate streams.

The maximum column count in Excel 97-2003 is 256 (A-IV) — which is why ancient CSV imports truncate at column IV.

KEUNGGULAN &
KETERBATASAN.

Keunggulan

Universal legacy — every Excel since 1997 opens .xls natively.
Binary format is compact and loads quickly.
Full support for formulas, charts, pivots, and VBA macros.
Deep integration with every accounting and ERP system of the 1990s-2000s.

Keterbatasan

Row/column limits are ~64× smaller than modern XLSX.
Macro-enabled variants are a notorious malware vector.
Binary corruption often means total data loss.
Cannot represent modern Excel features (dynamic arrays, LAMBDA, structured references).
Microsoft stopped evolving the format in 2007.
