Format Details

.xlsx

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.

.yaml

YAML

YAML (YAML Ain't Markup Language) is a human-friendly data serialization format designed to be more readable than JSON or XML for configuration files and structured data. It uses indentation and minimal punctuation to represent nested data structures, sequences, and mappings in a way that closely resembles natural language. YAML is the native configuration format for Kubernetes, Docker Compose, GitHub Actions, Ansible, and countless other modern developer tools.
