Reference
JSON vs XML vs CSV
Each format trades off differently — here's when each one actually fits.
| Format | Best For | Supports Nesting | Typical Use |
|---|---|---|---|
| JSON | APIs, config files | Yes | Web APIs, app configuration, NoSQL documents |
| XML | Documents, structured messaging | Yes | HL7/SOAP integrations, RSS, legacy enterprise systems |
| CSV | Tabular/spreadsheet data | No | Spreadsheet exports, bulk data import/export, reporting |
Beyond formatting a file
We build the integrations that move this data in the first place.
From HL7 feeds to REST APIs and bulk data exports, structured data integration is one piece of a larger interoperability strategy. That's what we do.
