Ghost2Jekyll: Converts ghost 0.4.2 sqlite db posts to jekyll 2.3.0 markdown posts.

Ghost to Jekyll

A utility that takes a Ghost 0.4.2 blog sqlite db file, extracts the posts and converts them to Jekyll 2.3.0 markdown format.

Requirements

  • Python 3

Quick Start

  • Download ghost2jekyll.py and post-template.md to a new folder.
  • Execute python3 ghost2jekyll.py --dbfile=/path/to/ghost.db

The posts are created in a subfolder called posts.
