JSON Line writer

Generate a JSONL file on which you can append multiple JSON elements line by line. Every line is written as compact single-line JSON terminated by a newline.

Example

// 1st input:
{ "hello": "World" }

// 2nd input:
{ "hello": "France" }

// Configuration:
// Header: { "type": "header" }

// Output:
{ "type": "header" }
{ "hello": "World" }
{ "hello": "France" }

Parameters

Header

A list of JSON values written before the records, one per line. Each entry must be a valid JSON value — this keeps every line of the file, header included, valid JSONL.

Footer

A list of JSON values written after the records, one per line, under the same rule as the header.

Input

JSON elementrequired

All the JSON elements to append to the JSON file. It accepts fragment of JSON which will be merged if possible, or overwritten. For example:

Fragments of JSON

{"name": "John"}
{"age": "27"}
{"age": "42"}

Merged JSON

{"name": "John", "age": "42"}
