About XLS
XLS is the older binary spreadsheet format used by Excel versions before 2007.
Still needed when working with legacy systems or older software that doesn't support XLSX.
XLS files are limited to 65,536 rows and 256 columns, a fraction of the modern XLSX capacity.
💡 The XLS binary format dates back to 1987, making it older than the World Wide Web itself.
About CSV
CSV (Comma-Separated Values) stores tabular data as plain text, with each line representing a row and commas separating columns.
The universal format for importing and exporting data between databases, spreadsheets, and analytics tools.
CSV has no official standard until RFC 4180 was published in 2005, decades after the format was already widely used.
💡 Despite the name, CSV files can technically use semicolons, tabs, or other delimiters instead of commas.
