Converting text to an array (JSON) or passing in different datatype objects to a function

[elibarber]

Using the JSONtext add-on with the sample text provided, I have quick success looping through each "methods" object, and displaying key value of each one. I plan on passing these arrays into .NET Framework methods later on.

I have two options:

1. How can I pass in a datatype to a function in labview.

2. Or, How can I convert a string "[ 2, 4, ..., 6]" for example into a LabVIEW array

If you are not 100% sure how cluster or the read json looks like in advance, consider using something like here:https://pettaa123.github.io/labview-blog/2023/01/09/Set-Cluster-Elements-by-Ref-from-JSON.html

In JavaScript converting a JSON string to an actual array is extremely easy:

var stringArray = "[1,2,3]";
var actualArray = JSON.parse(stringArray);
console.log(actualArray); // Output: [1, 2, 3]

 Is there way to do it quick and easy like this in labVIEW?

Hi elibarber,

Use the malleable VI "Find Item (as LVtype).vim" to directly specify the data type:

For your use case, you can also use "Find Multiple Items (as LVtype).vim":

Note:  This VIM is part of the JSONtext Toolkit by JDP Science.  I use this library in almost all of my applications anymore.  It is an amazing toolkit.
