What to expect

Frequently asked questions
Does SXC stay a working spreadsheet?
Yes. SXC is the StarOffice/OpenOffice.org 1.x Calc spreadsheet format, so cells and formulas are preserved as a spreadsheet rather than flattened to values.
Why convert an XLS to SXC?
SXC is the early ZIP-plus-XML spreadsheet format that predates ODF, useful when a file must match that legacy OpenOffice.org 1.x era format.
What opens an SXC file?
LibreOffice opens SXC directly on Windows, macOS and Linux.
Is SXC a good format to keep files in?
It is obsolete, so the practical step is usually to re-save the result as ODS or XLSX so it stays usable long-term.
