What happens to your file
LibreOffice opens the XLSX with its Calc filter and exports ODS. Calc has its own list of allowed outputs — a spreadsheet cannot be exported straight to a Writer or Impress format, which is why some targets route through an intermediate step instead.

What changes
- Formulas are exported as their last calculated values. Recalculate in the target app if the numbers need to stay live.
- If the document uses a font the server does not have, a substitution is picked before rendering — a close match, not the original. Line breaks and page counts can shift as a result, which is why it is worth opening an important file before sending it on.
