Privacy
JSON to TypeScript runs entirely in your browser on FileToolsHub. Your json is processed in this tab and is never uploaded to our servers.
That means passwords, tokens, personal notes, and documents you paste or load stay on your device. Clear the page or close the tab when you are finished on a shared computer.
You still need a network connection to load the page the first time. After that, the core processing for JSON to TypeScript does not require sending your content to FileToolsHub.
Limitations
- JSON to TypeScript depends on your browser. Very large inputs may slow or freeze older devices; try a smaller sample if the tab becomes unresponsive.
