How to Convert CSV to XML in Node.JS

When working with and transmitting raw data, CSV and XML are two of the most widely used file formats, with CSV providing a simple way to organize data and XML displaying data using markup language. XML, however, is the preferable format when needing to perform complex data manipulation or data transfer between an array of applications as it has wider support across programs than CSV. The following API will convert any CSV file to XML instantly; the parameters for the function are the input CSV file and a true or false input indicating whether column names should be used in the completed XML file.

You can use this API by running the following command to install the SDK:

npm install cloudmersive-convert-api-client --save

Or, you can add this snippet to your package.json:

"dependencies": {
"cloudmersive-convert-api-client": "^2.4.8"

Then, you can call the function:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDataApi();var inputFile = Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer); // File | Input file to perform the operation on.var opts = {
'columnNamesFromFirstRow': true // Boolean | Optional; If true, the first row will be used as the labels for the columns; if false, columns will be named Column0, Column1, etc. Default is true. Set to false if you are not using column headings, or have an irregular column structure.
var callback = function(error, data, response) {
if (error) {
} else {
console.log('API called successfully. Returned data: ' + data);
apiInstance.convertDataCsvToXml(inputFile, opts, callback);

You can retrieve the API Key for this function at no cost and with no commitment on the Cloudmersive website. This will give you access to 800 monthly calls across our entire API library.
