  2. Convert it to .DOCX in a few seconds.

What to expect

  • LibreOffice reads .sdw but cannot write back to it - always export to .docx or .odt immediately after opening.
  • SDW exists in three incompatible binary variants (StarWriter 3.x, 4.x, 5.x); very old files may import less accurately.
  • StarOffice-specific layout features have no Word equivalent and may be dropped or approximated in the .docx output.

Frequently asked questions

Can Microsoft Word open SDW files directly?
No - Word has no StarOffice SDW importer. Open the .sdw in LibreOffice Writer, save it as .docx, then open that file in Word.
Why can't LibreOffice save back to .sdw?
LibreOffice ships only a read filter for the legacy StarOffice binary format; it can import .sdw but writes only modern formats such as .docx and .odt.
Will my formatting survive the conversion?
Plain text and standard paragraph styles carry over well, but older StarWriter layouts and StarOffice-only features may shift or be dropped - review the document after converting.
Should I convert to DOCX or ODT?
Choose .docx for Microsoft Word compatibility; choose .odt if you want the closest preservation of the original structure and plan to stay in LibreOffice.
