How to Convert CSV to XML using Java

While there are various security concerns with data in XML format, there’s no doubt that XML represents a more flexible and web-focused data format option than CSV. If you’re looking to build that conversion into your application, we have an API that can help. Our CSV to XML API will handle that conversion instantaneously, and it’ll allow you to optionally specify if you are/are not using column headings. Below, we’ll walk through how you can structure your API call using code examples in Java.

First, let’s add the following reference to the repository in pom.xml to begin installing the Java SDK with Maven:

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

Then add a reference to the dependency in pom.xml:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

Now let’s add the import classes and call the API. Before you do so, ensure you have your input file parameter satisfied, and include your Cloudmersive API key for authentication. If you’re missing a key, you can get one easily by visiting our website and registering a free account:

// 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.ConvertDataApi;
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");
ConvertDataApi apiInstance = new ConvertDataApi();
File inputFile = new File("/path/to/inputfile"); // File | Input file to perform the operation on.
Boolean columnNamesFromFirstRow = true; // Boolean | Optional; If true, the first row will be used as the labels for the columns; if false, columns will be named Column0, Column1, etc.  Default is true.  Set to false if you are not using column headings, or have an irregular column structure.
try {
    byte[] result = apiInstance.convertDataCsvToXml(inputFile, columnNamesFromFirstRow);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertDataApi#convertDataCsvToXml");
    e.printStackTrace();
}

Just like that, you’re all done. No more code required, and your CSV to XML conversion needs are put to rest.
