Parse json containing date

Anonymous · ‎2018-09-07

Hi,

I have json as below. I need to get name, id and data values. Date under data changes everyday and I need dynamic json path to parse data field. Could some one please help ?

When I tried to perform metadata scanning from Json File, I am unable to get date under data dynamically.

    "id": 20,
    "data": {

@arunshankar , keep it in the same topic please !?! https://community.talend.com/t5/Design-and-Development/Parse-json-containing-hashmap/m-p/133144#M829...

As I've answered in the previous / linked topic... tJavaFlex... did you try? All of the talend JSON components need to map the 'key' to a column...

You could also write a custom routine where you load the "data" object from JSON and return a hashMap, arraylist or whatever you want.
If anybody has a different solution for this please let us know... because I also would like a component solution.
