Complete Guide to Handling JSON Strings in Java

When handling JSON data in Web APIs and configuration files, JSON compression (Minify) that removes unnecessary spaces and line breaks is an essential technique for reducing data transfer volume. This article thoroughly explains implementation code examples in major programming languages like JavaScript, Python, and Java.

In Java development, when you want to avoid complex dependencies and achieve lightweight and simple JSON processing, the json-simple library is an excellent choice. This article thoroughly explains basic operations from JSON data generation, parsing (reading), and value retrieval using JSONObject, the main class of json-simple, to array handling and comparisons with more modern libraries, all with specific code examples.

In Python data analysis, Pandas is the most powerful library, but there are many opportunities to handle JSON format data commonly used in Web APIs and configuration files. This article thoroughly explains basic operations from reading JSON files into DataFrames to outputting DataFrames as JSON, and advanced techniques for efficiently flattening complex nested JSON structures with specific code examples.
