It's a little ambiguous what you're after, without some examples of different inputs and what you would expect the outputs to be (and why).

Generally, you can't exactly "delete" something from a map, but similarly to the JSON approach, you could always structure an expression to build a new map from an existing map and just omit certain properties when needed.

it would be something like....

a!fromjson(substitute(a!tosjon(local!conditions), "logicalExpressions"":[]", null))

But you have to be care of closing tags, and keep the json structure

Can you pls give me an example for JSON approach

You ned to use a recursive approach... or try converting the array to json... replace the elements with a regular expression, and convert it again to an appian structure..

Yes you are correct

As far as I understand, this may require a recursive approach, given that the structure is hierarchical and can have multiple levels.
Please feel free to correct me if I’m mistaken.
