Bring content you already have into your Grav Helios projects.
Two browser-based tools that convert a Common Cartridge export or a Pressbooks export into ready-to-use Markdown pages for Grav Helios Course Hub or Grav Helios Open Reader – both designed to be an enjoyable, modern experience for the students or readers who'll use them. No installation required to see what carries over.
Upload your export and browse the converted Markdown right in your browser – no Grav or Helios installation needed to see what transfers.
Common Cartridge → Course Hub Modules, pages, learning objectives, embedded video, course image, license, and syllabus – arriving in Course Hub's weekly structure, with visual course cards and search scoped to the current course.
Pressbooks → Open Reader Sections, chapters, learning objectives, H5P activity links, cover image, license, and OER attribution – arriving in Open Reader's clean, distraction-free layout with light and dark mode.
Both converters produce plain Markdown files – portable text you can read, edit, and keep, whether or not you ever install Course Hub or Open Reader.
See before you commit Upload your export and browse example converted Markdown Previews right in your browser, or download the resulting Markdown file pages and review them on your desktop – no Grav or Helios installation needed to find out what the results of the move might look like.
A faithful match, not a rough draft Common Cartridge and Pressbooks exports both follow a single, consistent format, so each converter is purpose-built for one source and one destination – conversions are typically a close match to your original course or book, not something you have to substantially rebuild.
Free, with nothing to install or maintain No account, no license, no database. Upload a file, browse or download the result, and you’re done.
Built for the destination, not just the migration Converted content picks up real destination features automatically: Open Reader books get Keep My Place, so readers pick up right where they left off, and any single page of course or reader content can be embedded into Canvas, Moodle or other learning platforms.
