I Needed a way to migrate my Trello boards to a different platform. The only export option Trello offers is massive json file. Since my new platform doesn't offer a direct import of this format, had to write A small Kotlin program that parses the file by looping through each list, then printing out each card, the description, and a few other pieces of metadata to the console.
This program is very basic, as it is set up to to work for my simple needs.
Feel free to fork and customize to meet your needs.
gradle run --args="<path-to-trello-exported.json>"
