python-pptx-ng

python-pptx-ng is a Python library for creating, reading, and updating PowerPoint (.pptx) files.

This library is a continuation of the work done by Steve Canny (scanny) on the python-pptx_ project. The original project is no longer maintained and has been forked to continue development.

A typical use would be generating a PowerPoint presentation from dynamic content such as a database query, analytics output, or a JSON payload, perhaps in response to an HTTP request and downloading the generated PPTX file in response. It runs on any Python capable platform, including macOS and Linux, and does not require the PowerPoint application to be installed or licensed.

It can also be used to analyze PowerPoint files from a corpus, perhaps to extract search indexing text and images.

In can also be used to simply automate the production of a slide or two that would be tedious to get right by hand, which is how this all got started.

More information is available in the python-pptx-ng documentation_.

Release History

0.6.23 (2023-11-02) +++++++++++++++++++

• fix: #762 AttributeError: module 'collections' has no attribute 'abc' (Windows Python 3.10+)

0.6.21 (2021-09-20) +++++++++++++++++++

• Fix #741 _DirPkgReader must implement .contains()

0.6.20 (2021-09-14) +++++++++++++++++++

• Fix #206 accommodate NULL target-references in relationships.

• Fix #517 option to display chart categories/values in reverse order.
• Major refactoring of ancient package loading code.

0.6.19 (2021-05-17) +++++++++++++++++++

• Add shapes.add_ole_object(), allowing arbitrary Excel or other binary file to be embedded as a shape on a slide. The OLE object is represented as an icon.

0.6.18 (2019-05-02) +++++++++++++++++++

• .text property getters encode line-break as a vertical-tab (VT, '\v', ASCII 11/x0B). This is consistent with PowerPoint's copy/paste behavior and allows like-breaks (soft carriage-return) to be distinguished from paragraph boundary. Previously, a line-break was encoded as a newline ('\n') and was not distinguishable from a paragraph boundary.

  .text properties include Shape.text, _Cell.text, TextFrame.text, _Paragraph.text and _Run.text.

• .text property setters accept vertical-tab character and place a line-break element in that location. All other control characters other than horizontal-tab ('\t') and newline ('\n') in range \x00-\x1F are accepted and escaped with plain-text like "_x001B" for ESC (ASCII 27).

  Previously a control character other than tab or newline in an assigned string would trigger an exception related to invalid XML character.

0.5.0 (2014-09-13) ++++++++++++++++++

• Add support for creating and manipulating bar, column, line, and pie charts
• Major refactoring of XML layer (oxml)
• Rationalized graphical object shape access Note backward incompatibilities below

BACKWARD INCOMPATIBILITIES:

A table is no longer treated as a shape. Rather it is a graphical object contained in a GraphicFrame shape, as are Chart and SmartArt objects.

Example::

table = shapes.add_table(...)

# becomes

graphic_frame = shapes.add_table(...)
table = graphic_frame.table

# or

table = shapes.add_table(...).table

As the enclosing shape, the id, name, shape type, position, and size are attributes of the enclosing GraphicFrame object.

The contents of a GraphicFrame shape can be identified using three available properties on a shape: has_table, has_chart, and has_smart_art. The enclosed graphical object is obtained using the properties GraphicFrame.table and GraphicFrame.chart. SmartArt is not yet supported. Accessing one of these properties on a GraphicFrame not containing the corresponding object raises an exception.
