JSONとは

JSON (JavaScript Object Notation) is a text-based format for representing structured data. It uses key-value pairs and arrays to organize information. JSON is popular because it is lightweight, human-readable, and easy for machines to parse.

Common uses of JSON

  • Storing API responses (e.g., weather data, product catalogs, user details).
  • Configuration files for applications.
  • Transferring structured data between servers and browsers.

Example JSON:

{
  "name": "John Doe",
  "email": "john@example.com",
  "age": 29
}

What is CSV?

CSV (Comma-Separated Values) is a simple text-based format for storing tabular data. Each line in a CSV file represents a row, and each value is separated by commas.

Common uses of CSV

  • Import/export in Excel and Google Sheets.
  • Database uploads (MySQL, PostgreSQL, etc.).
  • Large datasets in analytics.

Example CSV:

name,email,age
John Doe,john@example.com,29
