What is a DOCX file?
DOCX stands for Word document. It was created by Microsoft and first released in 2007. DOCX has been Word's default format since 2007. Like XLSX it is a ZIP archive of XML files, which is how its text can be read without Word.

Tips for converting DOCX files without losing anything
Converting a DOCX file keeps the words exactly; what can change is formatting and layout, depending on what the target format can hold.
- Keep the original document; exporting to plain text or HTML drops layout that cannot be added back.
- Use HTML or Markdown when you want to keep headings, lists and links, and TXT when you only need the words.
- For scanned documents, OCR is the only way to get text; converting the file format alone will not find words in an image.
- Save text as UTF-8 so every language is preserved.
- Check headings after converting to HTML or Markdown; they come from the styles used in the original, so manual bold text stays plain text.
- Plain text has no pages, so page numbers and headers from the original document are dropped.
- For long documents, convert once and search the text output rather than scrolling the original.
- Markdown and HTML both keep links, so check that relative links still point somewhere once the document moves.
