Data Format Comparison Guide
| Format | Best For | Readability | Use Cases |
|---|---|---|---|
| JSON | APIs, web data | 🟢 Good | REST APIs, config files |
| XML | Legacy systems, SOAP | 🟡 Verbose | Enterprise, documents |
| YAML | Configuration files | 🟢 Excellent | Docker, Kubernetes |
| TOML | Config files | 🟢 Very Good | Rust, Python projects |
| CSV | Tabular data | 🟢 Simple | Spreadsheets, exports |
💡 Tip: For APIs
JSON is the de facto standard for modern REST APIs. Lightweight, fast, and universally supported.
💡 Tip: For Configs
YAML and TOML are most readable for configuration files. YAML for complex nested structures, TOML for simpler configs.
💡 Tip: For Data Export
CSV is perfect for tabular data exports that need to open in Excel or other spreadsheet applications.
