我需要将大型 CSV 数据集转换为 JSON,但输出应该是这样的 JSON 字典:
var products = {
"crystal": {
"description": "This is a crystal",
"price": "2.95"
},
"emerald": {
"description": "This is a emerald",
"price": "5.95"
}
};
This is what the CSV table would look like:

我正在使用引用的脚本here生成 JSON:
var csv = require('csv')
var fs = require('fs')
var f = fs.createReadStream('Fielding.csv')
var w = fs.createWriteStream('out.txt')
w.write('[');
csv()
.from.stream(f, {columns:true})
.transform(function(row, index) {
return (index === 0 ? '' : ',\n') + JSON.stringify(row);
})
.to.stream(w, {columns: true, end: false})
.on('end', function() {
w.write(']');
w.end();
});
然而,该脚本的输出是以这种格式创建的:
[
{
"name": "crystal",
"description": "This is a crystal",
"price": "2.95"
},
{
"name": "emerald",
"description": "This is a emerald",
"price": "5.95"
}
]
我将如何修改脚本以获得我想要的“字典”格式?
