How to Validate a CSV File in Node.js

There are a few common errors that can occur in CSV documents. Before we store those files or send them anywhere, we should double-check the quality of our data first.

Using the below ready-to-run Node.js code, we can quickly validate CSV files with a free-to-use API solution. If there are any errors in the document, we’ll receive a nested response object with an error description, a path to the error, and a URI to the error.

We can begin structuring our API call by first installing the Node.js SDK. We can either run the following command:

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

Or add the following snippet to our package.json:

  "dependencies": {
    "cloudmersive-convert-api-client": "^2.6.3"
  }

We can now copy the code examples below into our file and enter a free-tier API key to authorize our request. We can get our free-tier API key by registering a free account on the Cloudmersive website:

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.ValidateDocumentApi();

var inputFile = Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer); // 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.validateDocumentCsvValidation(inputFile, callback);

Now we can make quick API requests with CSV file form data and get quick results.
