===============

|PyPI| |Build Status| |Say Thanks!|

`oletools <http://www.decalage.info/python/oletools>`__ is a package of
python tools to analyze `Microsoft OLE2
files <http://en.wikipedia.org/wiki/Compound_File_Binary_Format>`__
(also called Structured Storage, Compound File Binary Format or Compound
Document File Format), such as Microsoft Office 97-2003 documents, MSI
files or Outlook messages, mainly for malware analysis, forensics and
debugging. It is based on the
`olefile <http://www.decalage.info/olefile>`__ parser.

It also provides tools to analyze RTF files and files based on the
`OpenXML format <https://en.wikipedia.org/wiki/Office_Open_XML>`__ (aka
OOXML) such as MS Office 2007+ documents, XPS or MSIX files.

For example, oletools can detect, extract and analyse VBA macros, OLE
objects, Excel 4 macros (XLM) and DDE links.

See http://www.decalage.info/python/oletools for more info.

Download and Install:
---------------------

The recommended way to download and install/update the **latest stable
release** of oletools is to use
`pip <https://pip.pypa.io/en/stable/installing/>`__:

-  On Linux/Mac: ``sudo -H pip install -U oletools[full]``
-  On Windows: ``pip install -U oletools[full]``

This should automatically create command-line scripts to run each tool
from any directory: ``olevba``, ``mraptor``, ``rtfobj``, etc.

The keyword ``[full]`` means that all optional dependencies will be
installed, such as XLMMacroDeobfuscator. If you prefer a lighter version
without optional dependencies, just remove ``[full]`` from the command
line.

To get the **latest development version** instead:
