Format Details
FWF
FWF (Fixed-Width Format) is a plain-text data format where each column occupies a predetermined number of character positions in every row, with no delimiter characters between fields. It originated on mainframes and is still common in government data releases, financial industry feeds, and legacy enterprise system exports. FWF files require a separate schema or data dictionary to correctly parse the column boundaries, making them less self-describing than CSV.
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.
