Converting a text file to JSON format using Adobe Acrobat: A tutorial on proper referencing

I am facing an issue with converting a string from a file attached to my PDF (JSONTEST.txt) into JSON format so that I can reference it using obj[key]. Despite trying to use eval(), I encounter the following error every time:

SyntaxError: missing ; before statement
5:Document-Level:jsontest

Here is the script I am currently using:

console.show(); console.clear();
var oFile = this.getDataObjectContents("JSONTEST.txt");
var cFile = util.stringFromStream(oFile, "utf-8");
var obj = eval(cFile);

What could be causing this error and how can I rectify it? Once resolved, will I be able to reference it as intended?

Answer №1

After some pondering, I have come to a realization, although I am still in the process of mastering the proper method for referencing fields. My JSON data was enclosed within curly brackets ( {} ), when it should have been placed inside square brackets ( [] ). It was as simple as that, so I made the adjustment:

var obj = eval('[' + cFile + ']');

And lo and behold, it appears to be functioning correctly now.
