Frequently asked questions
How do I convert DOCX to TXT?
LibreOffice command line: `libreoffice --headless --convert-to txt input.docx`. Pandoc: `pandoc input.docx -o output.txt`. In Word: File → Save As → Plain Text (.txt). All methods lose formatting — only the text content is preserved.
Does TXT support Unicode and emoji?
Yes — with UTF-8 encoding, TXT files support all Unicode characters including emoji, Chinese, Arabic, and every other script. When saving TXT, always choose UTF-8 encoding (not ANSI or Latin-1) for maximum compatibility with non-ASCII characters.
Can I open DOCX in Notepad?
Technically yes, but you'll see raw XML and binary data — not readable text. DOCX is a ZIP archive of XML files. To read the text content of a DOCX in a simple editor, extract the archive and open the word/document.xml file. Alternatively, LibreOffice Writer or Word Online (free) open DOCX properly.
