What is JSON?

JSON (JavaScript Object Notation) is a lightweight, human-readable format for exchanging structured data. It is the standard output of most REST APIs and is natively supported by JavaScript, Python, and hundreds of other tools.

When to use CSV vs Excel?

CSV is a plain-text format compatible with any spreadsheet application (Excel, Google Sheets, LibreOffice Calc) and any programming language. Use it when you need maximum compatibility or plan to process the data programmatically.

Excel (.xlsx) is a rich binary format that preserves data types (numbers, dates) and works directly in Microsoft Excel without import dialogs. Use it when sharing with non-technical users.
