JSON to CSV & CSV to JSON Converter – Free Online Tool

The JSON ⇄ CSV Converter by Qlix is a free online utility that allows you to convert JSON data into CSV format and CSV files back into JSON instantly. This tool is designed for developers, data analysts, SEO professionals, bloggers, and students who work with structured data and need fast, reliable format conversion without installing any software.

JSON (JavaScript Object Notation) is commonly used in APIs and web applications, while CSV (Comma-Separated Values) is widely supported by spreadsheet tools like Microsoft Excel, Google Sheets, and database systems. Converting between these formats helps make data easier to analyze, share, and reuse.

What Is JSON?

JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used in modern web development, REST APIs, configuration files, and mobile applications.

JSON stores data in key–value pairs and supports arrays and nested objects. Because of its flexibility, JSON is ideal for transferring complex structured data between systems. However, JSON is not always convenient for viewing or editing large datasets manually. 

 [ {"name": "John", "age": 30, "city": "Delhi"}, {"name": "Sara", "age": 25, "city": "Mumbai"} ]

What Is CSV?

CSV stands for Comma-Separated Values. It is a simple text-based format used to store tabular data where each row represents a record and each column represents a field.

CSV files are supported by almost all spreadsheet programs, data analysis tools, and database import systems. Because of its simplicity, CSV is often preferred for reporting, data analysis, and bulk data processing.
