Converters
The same data shows up in different shapes depending on where it lives — a YAML config, a CSV export, a JSON API response. These converters translate between those formats faithfully, respecting the fiddly rules each one carries: RFC 4180 quoting for CSV fields that contain commas or newlines, significant indentation and the boolean gotchas of YAML, and pretty-printed JSON on the way out. Converting a config to JSON to inspect it, or a spreadsheet export into records your code can consume, becomes a paste-and-copy step rather than a scripting chore. As with every client tool here, the data is transformed locally and never uploaded.
