CSV stands for Comma Separated Values. It’s a simple, text-based format for storing tabular data. Each line in a CSV file represents a row, and values within each row are separated by commas. This makes CSV files highly readable and easily importable into various applications like spreadsheets. For instance, a
CSV file might contain customer data with columns for name, email, and address.
Key features of CSV files
- Simplicity and readability: Easily understood and edited with basic text editors.
- Wide compatibility: Supported by most spreadsheet software and programming languages.
- Lightweight: Smaller file sizes compared to other formats like Excel.
- Limitations: Lacks data type information, making it less versatile than JSON for complex applications.
Understanding JSON Data
What is a JSON file?
JSON stands for JavaScript Object Notation. Unlike CSV, JSON is a human-readable data format that uses a key-value pair structure. It’s based on JavaScript, but it’s language-independent and is widely used for data interchange on the web. A JSON object is similar to a dictionary, where each key (in quotes) maps to a value. Values can be primitive data types (numbers, strings, booleans) or nested JSON objects and arrays.
Key features of JSON files
- Flexibility: Supports nested structures, allowing for complex data representation.
- Data types: Specifies data types (numbers, strings, booleans, arrays, objects), providing more context.
- Wide use in web applications: Used extensively for API communication and data storage.
- Readability: Relatively easy to read and understand compared to binary formats.
Why Convert Between CSV and JSON?
