Will this work dynamically for loop (such as “ForEachItem”)?
Be more specific , mostly its possible.
Explain what you are trying to achieve.
Say I have a json Data Array…I want for each number of item add something in a list and show it in a listview.
I have tried to use your extension in one of my recent project. I found that it returns only the value of index 1…rest of the value could not be processed. Then, the Json_tool by LukeGackle helped me. It extracted the data successfully from an array with ForEachNumber block.
Except this, I have found Json_Util extension by ColinTree the most easiest tool to extract data from json. I hope I was able to make u understand.
As there is a get array length block in the extension so you can use for each number from block.
Exactly same thing I’ve done…but I found the result of only index 1.
I think for complex json Data we need to parse the object repeatedly. And that’s not happening here.
Share some more details like apk,screenshot,demo,etc so that we can find what is wrong there.
Will try…
if possible share the JSON string.
If it’s sensitive share a similar structure.

I have personally messaged you the json file link… check it.
Link not working…

I think you forgot…
Could I get the source code from this extension for personal use? I’d like to add a feature myself
