Converting a string into a list extracted from a text document

Question

Within a file, the data (list) is structured as follows:

[5,[5,[5,100,-200],200,-400],300,-500]

Upon reading this file in an angular application, the contents are converted into a string object like so:

"[5,[5,[5,100,-200],200,-400],300,-500]"

Is there a way to revert this string back to its original list format?

While there is one method to tackle a different problem, where the file contains data:

The string can be split using:

var newData = fileContent.split('\n');
desiredList = []
for(var z=0;z<newData.length;z++){
        desiredList.push(parseInt(newData[z]))
    }

This provides the desired list structure. However, for the initial question posed, is there an alternative solution?

One way to utilize the eval() function is shown below:

var arr = "[10,[10,[10,500,-1000],1000,-2000],2000,-3000]";
var parsedArr = eval(arr);
console.log(parsedArr);
