Installation & Usage

Installation

You need to have Python with version in range 3.6 to 3.9 and pip installed on your system, then run in the terminal:

pip install pptx2md

(Python 3.10 breaks dependent package python-pptx)

Usage

Once you have installed it, use the command pptx2md [pptx filename] to convert pptx file into markdown.

The default output filename is out.md, and any pictures extracted (and inserted into .md) will be placed in /img/ folder.

Note: older .ppt files are not supported, convert them to the new .pptx version first.

Upgrade & Remove:

pip install --upgrade pptx2md

pip uninstall pptx2md

Custom Titles

By default, this tool parse all the pptx titles into level 1 markdown titles, in order to get a hierarchical table of contents, provide your predefined title list in a file and provide it with -t argument.

This is a sample title file (titles.txt):

Heading 1
  Heading 1.1
    Heading 1.1.1
  Heading 1.2
  Heading 1.3
Heading 2
  Heading 2.1
  Heading 2.2
    Heading 2.1.1
    Heading 2.1.2
  Heading 2.3
Heading 3

The first line with spaces in the begining is considered a second level heading and the number of spaces is the unit of indents. In this case, Heading 1.1 will be outputted as ## Heading 1.1 . As it has two spaces at the begining, 2 is the unit of heading indent, so Heading 1.1.1 with 4 spaces will be outputted as ### Heading 1.1.1. Header texts are matched with fuzzy matching, unmatched pptx titles will be regarded as the deepest header.

Use it with pptx2md [filename] -t titles.txt.

Other Arguments

• -t [filename] provide the title file
• -o [filename] path of the output file
• -i [path] directory of the extracted pictures
• --image-width [width] the maximum width of the pictures, in px. If set, images are put as html img tag.
• --disable-image disable the image extraction
• --disable-escaping do not attempt to escape special characters
• --disable-wmf keep wmf formatted image untouched (avoid exceptions under linux)
• --disable-color disable color tags in HTML
• --min-block-size [size] the minimum number of characters for a text block to be outputted
• --wiki / --mdk if you happen to be using tiddlywiki or madoko, this argument outputs the corresponding markup language
