I have this sample JSON response { “elements1”:[ { “id”:“1111”, “lineitems”: { “elements2”: [ { “name”: “One”, “modifications”: { “elements3”: [ { “name”: “large”, “quantity”: 5 }, { “name”: “medium”, “quantity”: 10 } ] } }, { “name”: “Two”, “modifications”: { “elements3”: [ { “name”: “large”, “quantity”: 6 }, { “name”: “medium”, “quantity”: 9 } ] } } ] }, “id”:“1111”, “lineitems”: { “elements2”: [ { “name”: “One”, “modifications”: { “elements3”: [ { “name”: “large”, “quantity”: 5 } ] } }, { “name”: “Three”, “modifications”: { “elements3”: [ { “name”: “large”, “quantity”: 6 }, { “name”: “medium”, “quantity”: 9 } ] } }, { “name”: “Four”, “modifications”: { “elements3”: [ { “name”: “large”, “quantity”: 6 }, { “name”: “medium”, “quantity”: 9 } ] } } ] } } ] } As you can see, elements2 may have none, one or more values. My question is how can you get the values of elements2 using a dynamic loop? Thank you in advance for your help. PS. Sorry, I don’t know how to indent appropriately. ---

It’s very helpful that you posted the JSON response but it’s not valid JSON. There must be a bracket missing. You can paste your JSON response into [Best JSON Viewer and JSON Beautifier Online](https://codebeautify.org/jsonviewer) on the left side and then click Tree Viewer to see the valid JSON (or error message) on the right side. **Edit:** It _was_ valid JSON but the forums converter your quotes to non-standard quotes. I replaced them and it now works on CodeBeautify. [This site](https://jsonlint.com/) will indent JSON (click Validate JSON). To keep the indentations when posting on the forums, include three back ticks (```) before and after the text. ```auto { “ elements1”: [{ “ id”: “1111”, “lineitems”: { “ elements2”: [{ “ name”: “One”, “modifications”: { “ elements3”: [{ “ name”: “large”, “quantity”: 5 }, { “ name”: “medium”, “quantity”: 10 }] } }, { “ name”: “Two”, “modifications”: { “ elements3”: [{ “ name”: “large”, “quantity”: 6 }, { “ name”: “medium”, “quantity”: 9 }] } }] }, “id”: “1111”, “lineitems”: { “ elements2”: [{ “ name”: “One”, “modifications”: { “ elements3”: [{ “ name”: “large”, “quantity”: 5 }] } }, { “ name”: “Three”, “modifications”: { “ elements3”: [{ “ name”: “large”, “quantity”: 6 }, { “ name”: “medium”, “quantity”: 9 }] } }, { “ name”: “Four”, “modifications”: { “ elements3”: [{ “ name”: “large”, “quantity”: 6 }, { “ name”: “medium”, “quantity”: 9 }] } } ] } }] } ``` Here’s what the Tree View looks like after replacing the quotes: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/b/8bf20e2a7b8c7c133985549aa622a1642b74a383.png) ---

See the screen titled “@arty3mm” in this project for an example of how to loop through the “elements2” property: [https://x.thunkable.com/copy/9a4fbb5093b10e308084b402c8a6101e](https://x.thunkable.com/copy/9a4fbb5093b10e308084b402c8a6101e) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/a/6a8d94f8b2abb6637f8ceadf5d259fda6b309c4f.png) Note that I’m using a shorthand property reference of “elements1[1].lineitems.elements2”. This is the same as getting the “elements2” property from the “lineitems” property from the first item of the list generated by the “elements1” property. ---

Hi Tatiang, Thank you for your answer. I was able to see your output and how your blocks work. Can I update the question to how are you going to display the JSON data like the one below: ID Name Size Quantity 1111 One Large 5 1111 One Medium 10 1111 Two Large 6 1111 Two Medium 9 1111 One Large 5 1111 Three Large 6 1111 Three Medium 9 1111 Four Large 6 1111 Four Medium 9 Each line can can be displayed in a single label joined together with wait control like in your sample blocks. Thanks. ---

Here’s an updated project that includes references to each of the properties you’re wanting: [https://x.thunkable.com/copy/80a8d28669a36e41bf91fc26f8474c74](https://x.thunkable.com/copy/80a8d28669a36e41bf91fc26f8474c74) It doesn’t loop through them but it may get you started on figuring out how to do that. ---

Hi Tatiang, Your last suggestion was the one I started before but I discovered that elements2 is a dynamic list, it can be none, one or more. This prompted me to ask for help. Can I use **For-Each Block** within **For-each Block** , the outer For-Each will be for the Name in elements1 and the inner For-Each will be for the Name and Modifications in elements2? But I’m not sure what to put in the **Get-Property** and **Of-Object** in the inner For-Each block. Thanks. ---

Yes, you can nest loop blocks. You may have to adjust the timing a little with a Wait 0 Seconds block (which actually waits more than 0 seconds!) but I’d try it first without any delays and see if it works. If you get stuck, post screenshots or a link to your project and we can go from there. Another option is to loop through the outer JSON array/list and store that in a variable. Then, in the second loop, use that variable as input for parsing the next info. That way you don’t have to worry as much about the timing. ---
