• Internet access is needed only during the first dependency installation.

Build a portable EXE on Windows

1. Download or clone this repository.
2. Open the project folder in Windows Explorer.
3. Run build_exe.bat.
4. After a successful build, the executable will be here:

dist\OfficeConvertorPortable.exe

The EXE name intentionally keeps the historical OfficeConvertorPortable spelling for compatibility with earlier local builds.

Run from source on Windows

py -3 -m venv .venv
.venv\Scripts\python.exe -m pip install --upgrade pip setuptools wheel
.venv\Scripts\python.exe -m pip install -r requirements.txt
.venv\Scripts\python.exe office_converter.py

Smoke tests

On Windows:

run_smoke_tests.bat

Cross-platform developer check, for example in CI:

python tests/smoke_tests.py

The smoke tests cover the translated UI labels, absence of removed branding, basic path helpers, image/PDF conversion helpers, PDF merge/split and Windows batch-file line endings. Microsoft Word COM automation is not tested outside Windows with Word installed.

Notes and limitations

• Word automation requires installed Microsoft Word and runs only on Windows.
• PDF → DOCX attempts to reconstruct document structure; complex layouts may not convert perfectly.
• Unsigned PyInstaller binaries can trigger antivirus warnings. Build from source if you need maximum trust.
• Before publishing binaries or choosing a project license, read docs/LICENSE_CHOICE.md and docs/THIRD_PARTY_NOTICES.md, especially the PyMuPDF licensing note.
