How to convert CSV to JSON in Node.JS

Let’s look at how to set up format conversion between CSV and JSON. I won’t lie to you, this is normally quite a chore. That said, I do have a nice shortcut to show you. Let’s dive in.

Before we do anything else, we need to add the following reference to our package.json file. This will begin installation of our API client and allow us to continue.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Next we just need to call our function: convertDataCsvToJson.

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';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDataApi();
var inputFile = "/path/to/file"; // File | Input file to perform the operation on.
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.convertDataCsvToJson(inputFile, callback);

Done! Yes, you read correctly, that’s all there is to it. Now any CSV file you input will be returned as a JSON.
