Convert json array to CSV using Apache common-io in Java

by loke Updated: Dec 28, 2022

The technique for converting a JSON array to a CSV file using Apache Commons IO in Java can be helpful in several situations where you want to export data stored in a JSON array to a CSV file. This may be helpful in the following cases, for instance:  

  • converting data saved in a database or other storage system that is represented as a JSON array;  
  • exporting data from a web application or API that returns data in JSON format;  
  • Transforming data from one format to another is part of the ETL (extract, transform, load) process. 

 

It offers a large selection of classes and methods that can be utilized to carry out different I/O-related operations, including reading and writing files, navigating directories and files, reading and writing to input and output streams, and more. When working with I/O operations in Java, Apache Commons IO is a valuable tool in your toolbox because it is a widely used library.  

Here is an example of how you can convert JSON array to CSV using Apache common-io in Java for your application:
