Format Details
JSON
JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format derived from JavaScript object literal syntax. It natively supports objects, arrays, strings, numbers, booleans, and null, allowing it to represent arbitrarily nested data structures. JSON has become the universal standard for REST API responses, configuration files, and data interchange on the web, with native parsing support in virtually every programming language.
XLSX
XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, built on the Open XML standard and standardized by ISO. It stores worksheets, formulas, charts, pivot tables, and formatting in a compressed ZIP archive of XML files, making it more compact and corruption-resistant than the older XLS format. XLSX is supported by Google Sheets, LibreOffice Calc, Apple Numbers, and virtually every modern data tool.
