How it works

Every key across every object becomes a column, values are quoted whenever they contain the delimiter or a line break, and nested objects are flattened into dotted column names such as address.city.

Frequently asked questions

What if objects have different keys?

The union of all keys becomes the header row, and missing values are written as empty cells.

How are nested objects handled?

They are flattened with dot notation, so {"user":{"id":1}} becomes a user.id column.
