About ODS and XLS

ODS (OpenDocument Spreadsheet) is the open ISO-standard spreadsheet format used by LibreOffice Calc and OpenOffice Calc.

XLS (Microsoft Excel 97-2003 Workbook) is Excel's legacy binary format, still common on older systems though superseded by XLSX.

What to expect: ODS and XLS support similar formatting, so most content and structure should carry over cleanly.
