How to convert XLSX to SDW
- Add your .XLSX file - drop it in the box above or click to browse.
- Convert it to .SDW in a few seconds.
- Download your new .SDW file.
What to expect
- SDW is a legacy word-processing format; spreadsheet data is flattened into a static table and formulas become values.
- Charts, pivot tables, and multi-sheet structure are not expected to survive.
- Support for SDW is limited to older suites and LibreOffice, so keep the original XLSX for future editing.
Frequently asked questions
What happens when I convert a spreadsheet to SDW?
SDW is a legacy StarWriter word-processing document, so this turns a spreadsheet into an old text-document format, with the cell data becoming a table in a word-processing file. It is an uncommon, backward-looking target.
Why would anyone convert XLSX to SDW?
Almost always for compatibility with very old StarOffice or StarWriter software that only reads the SDW format.
How faithful is the result?
Two things work against fidelity: the change from spreadsheet to word-processing document, and the age of the SDW format. Formulas become static values and rich spreadsheet features are not preserved.
Can modern software open SDW?
LibreOffice Writer can read SDW, but support elsewhere is limited, so converting the result to ODT or DOCX for ongoing use is wise.
