| Structure | Flat rows, columns, and sheets | Nested objects and arrays |
| Data types | Numbers, text, dates, booleans, formulas | Strings, numbers, booleans, null, nested objects |
| Formatting | Styles, colors, borders, charts | None (data only) |
| API compatibility | Not directly usable in APIs | The standard format for REST APIs |
| Programmatic access | Requires parser library | Native in JavaScript, Python, and most languages |
| Standard | ISO/IEC 26300 | ECMA-404 / RFC 8259 |
When to Convert
Common scenarios where this conversion is useful
Building API payloads from LibreOffice data
