About XLS and ODT

XLS (Microsoft Excel 97-2003 Workbook) is Excel's legacy binary format, still common on older systems though superseded by XLSX.

ODT (OpenDocument Text) is the open ISO-standard word processing format used by LibreOffice Writer and OpenOffice Writer.

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