Parse a Json(with array and objects) and export the data into Excel file in Node.js

Question

I am new to Node.js. My requirement is, I need to parse a JSON and export the data into Excel file with all the fields in the JSON.

My JSON is as follows:

Answer 1

You are using the json2xls module which accepts either on object or an array, but nested level object structure. What I mean is that your definition would be fine if introduction and objectives were scalar properties. I.e.

{
    "id": 1255,
    "title": "...)",
    "description": "...",
    "keyTerms": "...",
    "visible": true,
    "introduction": "string/int/float/bool/date",
    "objectives": "string/int/float/bool/date"
}

or

[
{
    "id": 1255,
    "title": "...)",
    "description": "...",
    "keyTerms": "...",
    "visible": true,
    "introduction": "string/int/float/bool/date",
    "objectives": "string/int/float/bool/date"
},
{
    "id": 1256,
    "title": "...)",
    "description": "...",
    "keyTerms": "...",
    "visible": true,
    "introduction": "string/int/float/bool/date",
    "objectives": "string/int/float/bool/date"
}
]

but in your case introduction is an object with nested elements, and objectives is an array of objects, which both are interpreted as [object] [object]

I do not know what you want in your excel file, but you need to decide how to flatten the structure first.
