Data Interchange Formats
Data formats define how structured information is stored and transmitted between systems. Choosing the right format depends on your use case: human readability, file size, parsing speed, and tool compatibility all play roles.
JSON (JavaScript Object Notation)
JSON is the dominant format for web APIs and configuration files. It represents data as key-value pairs with support for nested objects and arrays. JSON is human-readable, well-supported in every programming language, and relatively compact. Its main limitation is no support for comments.
CSV (Comma-Separated Values)
CSV is the simplest tabular format—rows of values separated by commas. It's universally supported by spreadsheet software and databases. CSV works well for flat, table-like data but struggles with nested structures. There's no formal standard, so quoting and escaping vary between implementations.
YAML (YAML Ain't Markup Language)
YAML prioritizes human readability using indentation instead of brackets. It's the standard for Kubernetes configs, Docker Compose, GitHub Actions, and Ansible playbooks. YAML supports comments and complex data structures but is sensitive to whitespace—a misplaced space can break a file.
XML (eXtensible Markup Language)
XML predates JSON and remains important in enterprise systems, SOAP APIs, and document formats like DOCX. It's more verbose than JSON but supports namespaces, schemas, and mixed content (text with embedded tags).
Conversion Considerations
- JSON to CSV: Flatten nested structures; arrays become multiple rows or columns
- CSV to JSON: First row becomes keys; each subsequent row becomes an object
- JSON to YAML: Direct structure mapping; YAML is often more readable for configs
