Hi HN! I use Trello as my personal KB and wanted a way to back it all up locally, but I decided that the .json wasn't enough - I wanted to be able to view it offline easily as well.<p>So I wrote t2md, which after backing up the .json files constructs a folder tree of markdown files and attachments to represent your boards, lists and cards. From each card the description, comments and checklists are formatted into separate markdown files. Any attachment URLs you've embedded as links or images are then updated to their new relative paths so they continue to display. (The readme shows an example).<p>This was also my project to learn modern C# .NET Core async, which means it runs fast, is cross-platform and is a single-file binary. Let me know what you think!
