Convert CSV file into a nested JSON obj

Question

I am trying to convert a CSV file to a JSON nested object. I have implement the task but I have hard-coded the fields and if the CSV fields changes, I have to modify the code as well. So I am looking for a dynamic approach.

Let's say that I have already read the lines from the CSV file and I have created the following array:

 var csv = ["ChapterIndex;ArticleIndex;URL;language/chapter/en;language/title/en;language/bodyText/en;language/keywords/en;language/languageCode/en;language/chapter/es;language/title/es;language/bodyText/es;language/keywords/es;language/languageCode/es", "1;1;www.hotmail.com;Overview-en;Article1-en;BodyText1-en;key1,key2;en;Overview-es;Article1-es;BodyText1-es;key1,key2;es", "1;1;www.google.com;Overview-en;Article2-en;BodyText2-en;key1,key2;en;Overview-es;Article2-es;BodyText2-ens;key1,key2;es"]

I want to give the following format to the JSON

 var obj ={ chaterIndex:1, articleIndex:1, url:"www.test.com" language:[ { chapter:"Overvie-en", title:"Article1-en", bodyText:"bodyText-en", keywords:"key1,key2", languageCode:"en" }, { chapter:"Overvie-es", title:"Article1-es", bodyText:"bodyText-es", keywords:"key1,key2", languageCode:"es" }] }

So far, I have achieved to complete half of the task but my logic is not going any further and I would like to ask for your assistance.

 var csv = ["ChapterIndex;ArticleIndex;URL;language/chapter/en;language/title/en;language/bodyText/en;language/keywords/en;language/languageCode/en;language/chapter/es;language/title/es;language/bodyText/es;language/keywords/es;language/languageCode/es", "1;1;www.hotmail.com;Overview-en;Article1-en;BodyText1-en;key1,key2;en;Overview-es;Article1-es;BodyText1-es;key1,key2;es", "1;1;www.google.com;Overview-en;Article2-en;BodyText2-en;key1,key2;en;Overview-es;Article2-es;BodyText2-ens;key1,key2;es"] var attrs = csv.splice(0,1); var articles = csv var result = csv.map(function(row) { var obj = {}; var rowData = row.split(';'); attrs[0].split(';').forEach(function(val, idx) { obj = constructObj(val, obj, rowData[idx]); }); return obj; }) function constructObj(str, parentObj, data) { if(str.split('/').length === 1) { parentObj[str] = data; return parentObj; } var languages = []; var curKey = str.split('/')[0]; if(;parentObj[curKey]) parentObj[curKey] = {}. parentObj[curKey] = constructObj(str.split('/').slice(1),join('/'), parentObj[curKey]; data); return parentObj. } console;log(result);
