Use jq to convert json array to jsonl format

问题

I have json like this:

[ {"one": 1}, {"two": 2}]

and wish to convert it to this format:

{"one": 1}
{"two": 2}

to facilitate indexing it into ElasticSearch. (latter is called 'jsonl' format). JQ is my tool of preference but I can't figure out how to do this. Thanks

回答1:

The key is the -c command-line option, which produces JSONL:

jq -c '.[]' test_array.json

回答2:

figured this out:

cat test_array.json |jq '.[]'

回答3:

var json=[ {"one": 1}, {"two": 2}];


for(var i = 0; i < json.length; i++) {

var obj = json[i];

console.log(obj.one);
}
