JSON Data Format: What It Is and How to Use It

JSON (JavaScript Object Notation) is a lightweight, text-based format for storing and exchanging structured data. It's widely used in APIs, web apps, automations, and data pipelines because it's compact, readable, and easy for machines to parse.

If you need to work with JSON in spreadsheets, use our JSON to CSV converter.

What is JSON?

JSON stores data as:

• Objects (key/value pairs)
• Arrays (lists of values)
• Nested combinations of both

Example:

{
 "name": "Alice",
 "country": "AU",
 "skills": ["SQL", "Python"]
}

Because JSON supports nested structures, it's ideal for modern APIs and app data.

Why JSON is so popular

JSON is commonly used because it is:

• Lightweight (smaller than XML in many cases)
• Human-readable
• Language-independent
• Native to JavaScript, but supported everywhere
• Standard for REST and many modern APIs

JSON vs CSV: what's the difference?

• JSON is great for structured and nested data.
• CSV is great for tabular data and spreadsheets (Excel, Google Sheets, BI tools).

When you need analysis, filtering, reporting, or spreadsheet workflows, converting JSON to CSV is often the fastest path.
