How to Convert RTF to HTML in Node.js

Converting any file type to HTML allows us to view content on our web browser client with ease.

Using the below code, we can convert our Rich Text Format (RTF) documents to HTML with a free API solution. To authorize our API request, we’ll just need a free-tier API key, which will allow us to make up to 800 conversions per month with no additional commitment.

To install the SDK, let’s either run this command:

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

Or add this snippet to our package.json:

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

Finally, let’s add the ready-to-run code examples below to our file:

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.ConvertDocumentApi();

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.convertDocumentRtfToHtml(inputFile, callback);

That’s all there is to it — no more code required!
