Java CSV to JSON and JSON to CSV Converter API - Installation
To export JSON to CSV or large CSV to JSON in java, I will be using the Java SDK of GroupDocs.Conversion Cloud API. This Java library is easy to install and offers a wide range of methods to achieve CSV to JSON and JSON to CSV conversion, without installing any 3rd party software. Java file format conversion API allows you to convert your documents and images of any supported file format to any format you need. Quickly convert between more than 50 types of documents and images online like Word, PDF, PowerPoint, Excel, HTML, CAD, raster images, etc.
However, you can either download the APIs JAR file or install API using Maven configurations. Add repository and dependency into your project’s pom.xml file. Below are the steps for Maven:
<repository> <id>groupdocs-artifact-repository</id> <name>GroupDocs Artifact Repository</name> <url>https://repository.groupdocs.cloud/repo</url> </repository>
<dependency> <groupId>com.groupdocs</groupId <artifactId>groupdocs-conversion-cloud</artifactId> <version>22.10</version> <scope>compile</scope> </dependency>
Please get your Client ID and Secret from the dashboard before following the mentioned steps. Once you have your ID and secret, add code snippet in a Java-based application:
