How to convert a PowerPoint PPTX to Text TXT in Java

Sometimes big clunky formats like PPTX can cause problems with compatibility, etc. At times like these, you need a quick means of simply converting these files into a more friendly simple format, such as plain text. Instead of going the parsing route, which takes forever to set up, we will be taking a shortcut that will have us finishing up in no time at all.

First we need our repository reference for Jitpack.

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

Then our dependency reference for our client.

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v3.54</version>
</dependency>
</dependencies>

And once our library is installed, we can proceed to call our function, as you see here.

// 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 {
TextConversionResult result = apiInstance.convertDocumentPptxToTxt(inputFile);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling ConvertDocumentApi#convertDocumentPptxToTxt");
e.printStackTrace();
}

Done!
