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"
