![]() ![]() One line of output per each innermost line item found. You may have multiple line items (so iterate over multiple keys), and you will have “hostname”, “cheese” # Two keys at this current levelĪ “line item” is the key iterated-over to produce each line of the csv.Ī line item is given with the ‘+’ sign before a key. (map access) operator applied on the “hostname” key “hostname” # Print key hostname at current level Unless you are using an op to change level, the quoted key should be followedĪ key may be anywhere before, after, or inside a line item,Īnd the keys will be output in the order they appear. If a key is NOT prefixed with an operation, it becomes a value printed. If the key is prefixed with an operation, it is used to REACH a value. The format str is a series of operations and keys, plus zero or more “line item”s.Įvery key name listed in the format string is quoted with double-quotes. ![]() Format Stringīecause csv is a fixed-format field and json is free-format, a meta language had to be developed to describe the various movements to find and output values into a fixerd format. JsonToCsv solves this by defining a meta language (format string) which can be used to define repeatable and fixed-format steps, allowing the flattening of the wide json domain space into the slim csv space. Csv on the other hand is a fixed single-type format. The problem with converting json to csv is that json is a dynamic, multi-typed, nested format. The output csv is RFC 4180 compliant by default (behaviour can be changed with options). Converts json data to csv via a meta language (format string)
