Converting JSON to CSV is a common task, especially when you need to process data for analysis, or when you want to generate a human-readable, tabular format for data that's originally in JSON. Since CSV (Comma-Separated Values) is widely used for spreadsheets (like Excel or Google Sheets), it's a useful format for exporting data.
There are several ways to convert JSON to CSV in Java, using libraries such as Jackson, Gson, or OpenCSV.
Why Convert JSON to CSV?
Data Analysis: CSV is a widely accepted format for data analysis tools like Excel, R, or Python's pandas.
Data Export: Many systems or applications require data in CSV format for export or report generation.
Simplicity: CSV is a simple and lightweight format, perfect for flat data.
There are several ways to convert JSON to CSV in Java, depending on the libraries you prefer or are already using:
Jackson: Great for complex data and when you need both JSON and CSV capabilities in one library.
Gson with OpenCSV: A straightforward combination that allows for easy JSON parsing and CSV writing.
OpenCSV: A powerful tool for handling CSV writing, combined with either Jackson or org.json for JSON parsing.
