Flatten array objects with parent values? · Issue #646 · stedolan/jq , Is there a generic pattern in jq to flatten a 1-level nested array like this? $in.date] + [$h[]]|@csv' 646.json 1,"2014-12-30",1,"2014-12-30" Approach to flatten JSON. There are many ways to flatten JSON. There is one recursive way and another by using the json-flatten library. Recursive Approach: Now we can flatten the dictionary array by a recursive approach which is quite easy to understand. The recursive approach is a bit slower than using json-flatten library. Example:
Wrestling JSON with jq by Arjan van der Gaag, Jq is a command-line tool to tranform JSON streams into other JSON construct paths through our JSON document by joining nested keys with For learning how to construct jq queries, it is more useful to look at the tutorial and manual than the "man" page.
