About Data Converters
Every pairing between the formats structured data actually travels in: JSON, XML, YAML, CSV, TSV, TOML, HTML tables and RSS feeds. Converting between a nested format and a flat one is where most converters quietly lose information, so nested objects are expanded into addressable columns on the way out to CSV or TSV rather than being stringified or dropped, and column names that would be invalid XML element names are repaired automatically instead of producing a document that will not parse. Going the other way, a table with ragged rows is padded rather than truncated, and values that look like numbers or booleans are recognised as such where the source format has no types to tell you. The result is a working document you can use directly, not something you have to repair afterwards.
