About TXT and ODT

Plain Text .txt

Just characters. No fonts, no sizes, no layout — which is exactly why it will still open, unchanged, in fifty years.

Good for

  • Universally readable, now and indefinitely
  • Tiny, and works with every text tool ever written
  • Nothing hidden — what you see is the whole file

Trade-offs

  • No formatting, images or structure whatsoever
  • Character encoding must be right or accents break
  • Line endings differ between Windows and everything else

text/plain

OpenDocument Text .odt

The OpenDocument text format — an ISO-standardised, vendor-neutral alternative to DOCX, and the native format of LibreOffice.

Good for

  • An open standard, not tied to one vendor
  • Native to LibreOffice and OpenOffice
  • Preferred or mandated by many public bodies

Trade-offs

  • Word opens it but does not always round-trip it cleanly
  • Less common in commercial workflows

What changes when you convert TXT to ODT

It becomes editable, not formatted

The result is a genuine ODT you can open and edit in a word processor — but a text file carries no formatting to bring with it, so what you get is your text in a default typeface with default margins. Headings, styles and structure are yours to add afterwards. Nothing in a TXT tells the converter which line was meant to be a title.

Rendered by LibreOffice

The conversion runs through headless LibreOffice — the same engine behind the desktop suite. Fonts are the thing to watch: the document is typeset with what the server has available, and a substituted typeface rarely occupies exactly the same width as the one it replaces, so line breaks can fall differently than they would on your machine.

Read as UTF-8

A TXT is a text file, and a text file does not record which encoding it uses — that is the one thing the format cannot tell you about itself. We read it as UTF-8, which is right for essentially anything produced this decade. A file saved long ago in a regional encoding can arrive with accented characters mangled, and the fix is to re-save it as UTF-8 before converting rather than after. Tabs and spaces used to line columns up will also shift once the text is set in a proportional typeface.
