Yes, it must be a simple ASCII text file.
Open Document Text format doesn't work, so the file extension .odt is misleading here.
I assume the coordinates file was created with LibreOffice Writer and then saved as text format.
In this case it is better to name the file whatever.txt.

Alternatively use more basic text editors like Notepad or Gedit for this, as they use text format by default.

Or, as mentioned in this post:

You can use Excel or LibreOffice Calc and export as CSV file. This option is unbeatable when the coordinates are described by an equation.
Then the spreadsheet can do the math and you have a base for parametrable drawings.

Anyhow, many thanks for writing this down and share your experience.
I think we should transfer this to our wiki and also take it into account for the documentation.
