json-2-csv
Advanced tools
The json-2-csv npm package is a utility for converting JSON data to CSV format and vice versa. It is useful for data transformation tasks, especially when dealing with data interchange between systems that use different formats.
Convert JSON to CSV
This feature allows you to convert an array of JSON objects into a CSV string. The code sample demonstrates how to use the json2csv function to transform JSON data into CSV format.
const json2csv = require('json-2-csv');
const json = [
{ name: 'John', age: 30, city: 'New York' },
{ name: 'Anna', age: 22, city: 'London' },
{ name: 'Mike', age: 32, city: 'Chicago' }
];
json2csv.json2csv(json, (err, csv) => {
if (err) {
throw err;
}
console.log(csv);
});
Convert CSV to JSON
This feature allows you to convert a CSV string into an array of JSON objects. The code sample demonstrates how to use the csv2json function to transform CSV data into JSON format.
const json2csv = require('json-2-csv');
const csv = 'name,age,city\nJohn,30,New York\nAnna,22,London\nMike,32,Chicago';
json2csv.csv2json(csv, (err, json) => {
if (err) {
throw err;
}
console.log(json);
});
Custom Delimiters
This feature allows you to specify custom delimiters for fields and arrays when converting JSON to CSV. The code sample demonstrates how to use the json2csv function with custom delimiter options.
const json2csv = require('json-2-csv');
const json = [
{ name: 'John', age: 30, city: 'New York' },
{ name: 'Anna', age: 22, city: 'London' },
{ name: 'Mike', age: 32, city: 'Chicago' }
];
const options = {
delimiter: {
field: ';',
array: '|'
}
};
json2csv.json2csv(json, (err, csv) => {
if (err) {
throw err;
}
console.log(csv);
}, options);
The csv-parser package is a streaming CSV parser that converts CSV data into JSON objects. It is highly efficient for processing large CSV files. Unlike json-2-csv, which provides both JSON to CSV and CSV to JSON conversion, csv-parser focuses solely on parsing CSV to JSON.
The papaparse package is a powerful CSV parser that can handle large files and supports web workers for asynchronous parsing. It offers both CSV to JSON and JSON to CSV conversion, similar to json-2-csv, but with additional features like streaming and chunking for large datasets.
The fast-csv package is a comprehensive library for parsing and formatting CSV data. It supports both reading from and writing to CSV files, similar to json-2-csv. However, fast-csv is designed for high performance and can handle large datasets efficiently.
This is a node script that will let you convert JSON into a CSV string.
