How to convert Excel XLSX to PDF in Java

Today we will look at how to convert the all-important Excel spreadsheet into the more-presentable PDF document, for all your web displaying and printing needs.

The first thing that we need to do is add references to the Maven POM file.

Repository reference:


Dependency reference:


And then pull the trigger on convertDocumentXlsxToPdf:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.ConvertDocumentApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
ConvertDocumentApi apiInstance = new ConvertDocumentApi();
File inputFile = new File("/path/to/file"); // File | Input file to perform the operation on.
try {
byte[] result = apiInstance.convertDocumentXlsxToPdf(inputFile);
} catch (ApiException e) {
System.err.println("Exception when calling ConvertDocumentApi#convertDocumentXlsxToPdf");

And you’re done! Now you can go enjoy all the time you just saved. A useful related API is called convertDocumentAutodetectToPdf, which provides the same functionality, but with the ability to accept most document formats as inputs and without the need to specify said formats.
