or **easy_install olefile** for the first installation.
To update olefile, run **pip install -U olefile**.
Otherwise, see http://olefile.readthedocs.io/en/latest/Install.html
Features
--------
- Parse, read and write any OLE file such as Microsoft Office 97-2003 legacy document formats (Word .doc, Excel .xls,
PowerPoint .ppt, Visio .vsd, Project .mpp), MSI files, Image Composer and FlashPix files, Outlook messages, StickyNotes,
Zeiss AxioVision ZVI files, Olympus FluoView OIB files, etc
- List all the streams and storages contained in an OLE file
- Open streams as files
- Parse and read property streams, containing metadata of the file
- Portable, pure Python module, no dependency
olefile can be used as an independent package or with PIL/Pillow.
olefile is mostly meant for developers. If you are looking for tools to analyze OLE files or to extract data (especially
for security purposes such as malware analysis and forensics), then please also check my
[python-oletools](https://www.decalage.info/python/oletools), which are built upon olefile and provide a higher-level interface.
Documentation
-------------
Please see the [online documentation](http://olefile.readthedocs.io/en/latest) for more information.
