odt

Two ODT files: a 1 page document of 4.7 KB and a 10 page document of 4.8 KB. ODT is the OpenDocument text format used by LibreOffice, and it is a government and open-source standard in many countries. Like DOCX it is a zip of XML, but with its own structure, so tools that read Word files often fail on it. Use these files to test whether your site accepts .odt, whether previews and text extraction work, and whether a converter to PDF is able to read it. The 10 page version helps with page count and pagination checks.
