jolt | JSON to JSON transformation library written in Java | JSON Processing library

There should be a logical relation between buttons state and checkbox state, something like this:

You can prepend the values of the attributes other than test1 by label[0] while distinguishing objects by prepending &1 as the leading in order to substitute the indexes of them element such as

You can use a shift transformation spec such as

You can refine more by adding @(3,poi_id) as value (as being right hand side, raise the needed level from 2 to 3) in order to distinguish objects more such as

One more level of node is needed. For this aim, you can prepend all values of the innermost attributes by &1..

Then an extra shift transformation is added to remove unwanted key names and square brackets wrapping the objects.

So, you can use the following specs :

You should add each added node and use "*" wildcard to represent the rest of the attributes within the cardinality transformation such as

You can use shift transformations along with # operators in order to represent the fixed element values for the new lists to be created.

For the first case( if we have "arrayModule": ["KK", "VV"] for the input ) :

Just nest one more step by replacing the part

"link_promo": "promo_links[]" with "link_promo": { "*": "promo_links" }

in order to reach innermost part of the JSON as in the following spec

You're so close to reach the solution. Just seperate the values by @(3,base) while walking through the indexes of the frontItem list such as
