console.log(csv);
});

Use as a module
Example 1
var tocsv = require('tocsv');
var json = [
{
"car": "Audi",
"price": 40000,
"color": "blue"
}, {
"car": "BMW",
"price": 35000,
"color": "black"
}, {
"car": "Porsche",
"price": 60000,
"color": "green"
}
];
tocsv({data: json, fields: ['car', 'price', 'color']}, function(err, csv) {
if (err) console.log(err);
fs.writeFile('file.csv', csv, function(err) {
if (err) throw err;
console.log('file saved');
});
});
The content of the "file.csv" should be
car, price, color
"Audi", 40000, "blue"
"BMW", 35000, "black"
"Porsche", 60000, "green"
Example 2
Similarly to mongoexport you can choose which fields to export
tocsv({data: json, fields: ['car', 'color']}, function(err, csv) {
if (err) console.log(err);
console.log(csv);
});
Results in
car, color
"Audi", "blue"
"BMW", "black"
"Porsche", "green"
Example 3
Use a custom delimiter to create tsv files. Add it as the value of the del property on the parameters:
tocsv({data: json, fields: ['car', 'price', 'color'], delimiter: '\t'}, function(err, tsv) {
if (err) console.log(err);
console.log(tsv);
});
Will output:
car price color
"Audi" 10000 "blue"
"BMW" 15000 "red"
"Mercedes" 20000 "yellow"
"Porsche" 30000 "green"
If no delimiter is specified, the default ,
is used
Example 4
You can choose custom column names for the exported file.
tocsv({data: json, fields: [ { name:'car', label:'Car Name'}, { name:'price','Price USD' } ] }, function(err, csv) {
if (err) console.log(err);
console.log(csv);
});
Results in
"Car Name", "Price USD"
"Audi", "blue"
"BMW", "black"
"Porsche", "green"
