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:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Dependency reference:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v2.32</version>
</dependency>
</dependencies>

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)
//Apikey.setApiKeyPrefix("Token");
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);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertDocumentApi#convertDocumentXlsxToPdf");
    e.printStackTrace();
}

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.
