Note

GroupDocs.Parser for Python via .NET ships as a self-contained wheel that bundles the .NET runtime it needs. No Microsoft Office, third-party document editor, .NET install or Mono install is required. On Linux and macOS a few system packages are needed; see Platform Dependencies. To install the library, follow the steps in the Installation guide.

GroupDocs.Parser for Python via .NET runs on Windows, Linux, and macOS. The package ships as a platform-specific .whl on PyPI and pip picks the correct one automatically.

• Microsoft Windows 10 (x64)
• Microsoft Windows 11 (x64)
• Microsoft Windows Server 2016 and later

The Windows wheel is 64-bit only: use a 64-bit Python. Version 25.12 also shipped a 32-bit wheel; 26.10 does not.

• Any x86-64 distribution with glibc 2.27 or newer - for example Ubuntu 18.04+, Debian 10+, RHEL 8+. The embedded .NET runtime needs glibc 2.27, and the wheel’s manylinux_2_27_x86_64 tag says so, so pip refuses an older system.

• macOS 13 (Ventura) and later - Intel and Apple Silicon (M-series). The wheels are tagged macosx_13_0_*.
• OCR needs macOS 13.3 or newer. Recognizing text in scanned pages and images uses the bundled ONNX Runtime library, which declares macOS 13.3. On macOS 13.0-13.2 an OCR call (TextOptions(False, True), or text from an image file) raises GroupDocsParserException naming Microsoft.ML.OnnxRuntime.NativeMethods and DllNotFoundException; every other feature works. Update macOS to use OCR.
• Microsoft supports .NET 10 on macOS 14 and later; the embedded runtime itself starts on macOS 12.

GroupDocs.Parser for Python via .NET supports Python 3.5 through 3.14. The wheel uses the py3-none-{platform} tag, meaning it works with any Python 3.x version in that range without per-version rebuilds.

GroupDocs.Parser for Python via .NET is distributed via PyPI:

pip install groupdocs-parser-net

The PyPI index hosts one wheel per platform:

pip 20.3 or newer picks the right wheel for your platform; older versions do not recognise these tags, so upgrade with python -m pip install --upgrade pip (on Python 3.5, python -m pip install "pip==20.3.4"). On an Intel Mac, a Python built against a pre-11 macOS SDK reports its system as macOS 10.16 - there use pip 24.1 or newer, or run SYSTEM_VERSION_COMPAT=0 pip install groupdocs-parser-net.

Install ICU, fontconfig, the Liberation fonts and libgdiplus:

sudo apt-get update
sudo apt-get install -y libicu-dev libfontconfig1 fonts-liberation libgdiplus

What each package is for, measured on the 26.8 engine that 26.10 ships:

• ICU (libicu-dev, any version your distribution ships) - without it the runtime cannot start: the first call aborts the Python process with “Couldn’t find a valid ICU package”. Do not set DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 to work around it.

• fontconfig (libfontconfig1) - the bundled SkiaSharp library loads libfontconfig.so.1.

• Liberation fonts (fonts-liberation) - without them, get_structure() reports the merged cells of a Word table at the wrong row and with the wrong row span. Other fonts (DejaVu, Carlito, Caladea, or the Microsoft core fonts) do not take their place.

• libgdiplus (libgdiplus) - presentations need it. Without it, these raise GroupDocsParserException naming the Gdip type initializer and DllNotFoundException:

  • the page preview of every PowerPoint and OpenDocument presentation;
  • every operation except get_metadata() on ODP and OTP files, and on PPT, PPS and POT files that contain a table;
  • get_hyperlinks() on a PowerPoint file that contains a table or a hyperlink.

  Every other format works without it.

Note

Not required: the Microsoft core fonts (ttf-mscorefonts-installer). Every example in this documentation gives the same output with and without them.

Install mono-libgdiplus for presentations, as on Linux:

brew install mono-libgdiplus

Nothing else is needed.

If you see a DllNotFoundException: libSkiaSharp error after upgrading, an older system copy of SkiaSharp is shadowing the one bundled with the wheel. Rename it so the bundled copy wins:

sudo mv /usr/local/lib/libSkiaSharp.dylib /usr/local/lib/libSkiaSharp.dylib.bak

No extra dependencies - the wheel is self-contained.

GroupDocs.Parser for Python via .NET can be used with any text editor or IDE that supports Python development, including PyCharm, Visual Studio Code, Jupyter Notebook and Spyder.
