This is a CSV to JSON converter that I developed on top of Mr. Data Converter, allowing CSVs to be tranlated into JSON, and other formats, and back again. The part I added was the ability to save on Github, using an entirely client-based solution leveraging the Github API to write JSON, CSV and other files to the master repository.
API Evangelist Tools
While not all my tools are ready for prime time, I try to keep them each in their own Github Repo, with as much of the backstory, code, data, and other definitions needed to understand what is going on. When I feel a tool is relevant, or maybe publish a story about it, I will usually add it to this list of API Evangelist tools, and share as part of my regular research, and even sometimes to operate my business.
I am working to update these regularly, and add new ones for other areas of my research, and running API Evangelist when I can. While many of my tools are functional, and I actively use them in my work, you should check with me before ever puttting them into a production environment.
If there is a specific area you'd like to see a tool for, feel free to let me know. I'm happy to priotize a specific stop along the API lifecycle, as well as take on paid work to develop micro tooling, when it contributes to the API community.
