Format Details
XLS
XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1987 through the Office 2003 era, based on Microsoft's proprietary Binary Interchange File Format (BIFF). It stores worksheets, formulas, charts, and macros in a binary structure that requires Microsoft's format specification to parse correctly. XLS remains common in older enterprise systems and when compatibility with legacy versions of Excel is required.
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.
