JSON
JSON (JavaScript Object Notation) stores structured data as human-readable text using key-value pairs, arrays, and nested objects. Lightweight and language-independent. Uses curly braces for objects, square brackets for arrays. Supports strings, numbers, booleans, null. Maximum size limited by parser implementation. Universal data interchange format for APIs and configuration. Based on JavaScript syntax but language-agnostic.

No compression—larger files than XLSX. Maximum 65,536 rows and 256 columns per sheet. Gradually replaced by XLSX since Office 2007 but widely compatible with older systems.
