About XLSX
XLSX is Microsoft Excel's spreadsheet format, storing rows, columns, formulas, and formatting in a compressed XML archive.
The standard choice for budgets, data tables, and anything requiring formulas or multiple sheets.
A single XLSX sheet can hold over 1 million rows and more than 16,000 columns.
💡 Excel's grid limit was only 65,536 rows until 2007. The modern 1,048,576-row limit is exactly 2^20.
