Should I just write the whole post in a markdown card and copy to export it? Or does better ways exist?
I found this website which converts an URL http://heckyesmarkdown.com, but I wanted to know if there is some better alternative?
This is for an external story to be published on another website.
@MLFromScratch heckyesmarkdown.com sounds like a reasonable tool for the job if it’s a one-off, there are likely similar ones available all based on different underlying parsing/stringifying libraries.
https://unifiedjs.com is a really good go-to resource for doing this sort of thing if you’re a coder :) If you wanted markdown-formatted versions of all your content you could take the html value of posts via Ghost’s Content API and put them through a rehype.parse -> remark.stringify pipeline to get a markdown version (there’s a specific plugin for that).
Thanks Kevin, this looks good. This is most probably the first of many times I will need to export.
I’m not sure there is an advantage to the rehype plugin though, why would it be better? 
That comment was focused on tools to build an automated pipeline if this was something you needed to do for every post.
