Getting Started

System Requirements

Aspose.Cells for Python via .NET is a platform‑independent API and can be used on any platform (Windows, Linux, and macOS) where Python is installed.

Python Version

  • Python 3.6 or higher

Installation

Windows:

You can easily use Aspose.Cells for Python via .NET from PyPI with the following command. 

 $ pip install aspose-cells-python

Linux:

You can easily use Aspose.Cells for Python via .NET from PyPI with the following command. 

 $ pip install aspose-cells-python

  • Note: You need to run the following command before installation 
    For Ubuntu/Debian: apt-get install libgdiplus 
For CentOS/RHEL/Fedora: yum install libgdiplus

macOS:

You can easily use Aspose.Cells for Python via .NET from PyPI with the following command. 

 $ pip install aspose-cells-python

  • Note: If your Python version is 3.7 (take Python 3.7 as an example), after installing aspose-cells-python, you may encounter errors such as
    '/usr/local/lib/libpython3.7m.dylib' (no such file) or '/usr/lib/libpython3.7m.dylib' (no such file).
    In such a situation, please add the following commands to your ~/.bash_profile (first locate where libpython3.7m.dylib resides, e.g., /Library/Frameworks/Python.framework/Versions/3.7/lib): 

    export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Library/Frameworks/Python.framework/Versions/3.7/lib"
export LIBRARY_PATH="$LIBRARY_PATH:/Library/Frameworks/Python.framework/Versions/3.7/lib/"

  • Note: Due to our reliance on the SkiaSharp graphics library, if you encounter the following error:

System.DllNotFoundException: Unable to load shared library ‘libSkiaSharp’ or one of its dependencies.

please install SkiaSharp. 

brew install nuget
nuget install SkiaSharp.NativeAssets.macOS -Version 2.88.6
After installation, run the following command: 
cp ./SkiaSharp.NativeAssets.macOS.2.88.6/runtimes/osx/native/libSkiaSharp.dylib /usr/local/lib/.

Of course, if you want a simpler approach, you can also download libSkiaSharp.dylib and then copy it to the /usr/local/lib directory.

⚠️ Note:
In some cases, after installing a new version of aspose-cells-python, users may encounter an error like the following:

While initializing the host for the ‘WrpNs_Aspose.WrpNs_Cells.WrpCs_Workbook_xxxxxx (Assembly=WrpInterop.Aspose.Cells)’ type, an error occurred – Method ‘call_000_xxxxxx’ not found

This indicates that the previous version was not completely uninstalled, leading to a conflict between the newly installed version and the old one.
You can resolve this issue by following the steps below:

  • First, create a clean virtual environment to ensure the latest version works properly on your Windows machine:
# Set up virtual environment
python -m venv .venv
.\.venv\Scripts\activate
# Install aspose-cells-python
pip install aspose-cells-python

Then run your program.

  • If you prefer to continue using your original environment, please try the following steps:
pip uninstall aspose-cells-python

Make sure the uninstallation is successful. If any errors occur during uninstallation, try running the command multiple times.

Alternatively, locate your site‑packages directory, typically something like:

\Python3x\Lib\site-packages

Then manually delete the following directories (if they exist):

aspose
aspose_cells*

After that, reinstall the package:

pip install aspose-cells-python
