csvjson.com retired? Or just want more? csvtodashboard does CSV↔JSON with real type detection — numbers, booleans, nulls preserved — plus NDJSON, nested flattening, validation and 170 more tools, locally in your browser.
CSVJSON earned its place as the go-to CSV↔JSON converter for years — simple, predictable, and good enough for everyday payloads. Plenty of developers still have it bookmarked.
| csvtodashboard | CSVJSON | |
|---|---|---|
| Type fidelity | Conversions are type-aware: numbers stay numbers, booleans stay booleans, empty cells can be null — not everything-as-strings. | Simple converters often emit all values as strings. |
| Direction & dialects | Both directions plus the neighbors: NDJSON, JSON→Excel/SQL/typed schemas (TypeScript, Zod, Pydantic), nested-JSON flattening with honest one-way labeling. | CSVJSON covers the classic pair. |
| File size | Multi-hundred-MB files are fine — parsing runs off the main thread. | Paste-area tools are sized for paste-able data. |
| Privacy | Everything runs locally; nothing is uploaded. | Varies by tool — check each site's policy. |

Drop a CSV on the dashboard builder or open the editor with DevTools' Network tab open — you'll see your file never leaves the machine. That's the architectural difference everything else flows from.
