Tabular-JSON
Tabular-JSON is a data format. It is a superset of JSON, adding CSV-like tables and optional quotes. It is:
- A replacement for CSV without its ambiguities and limitation of tabular data structures
- A replacement for JSON without its verbosity
- A replacement for NDJSON without its verbosity
Tabular-JSON aims to be just as simple as JSON and CSV. It combines the best of JSON, CSV, and NDJSON, but without their drawbacks. It is human-readable, compact, and supports rich data structures and streaming. The aim of Tabular-JSON is to be a data format, not a configuration format.

swimming,
biking
],

2, joe, New York, "1st Ave"
3, sarah, Washington, "18th Street NW"
---,
address: {
city: New York,
street: "1st Ave"
}
