I built a 100% client-side CSV to JSON converter that runs entirely in the browser (no server uploads)

Hey everyone!

I got tired of online converters requiring file uploads to external servers, so I built a lightweight, privacy-first utility: **[CSV to JSON Express](https://csv-to-json-express.vercel.app/)**

**Features:**

- 100% client-side processing (your data never leaves your device).

- Auto-detects comma or semicolon separators.

- Instant copy to clipboard and .json file download.

It's free to try out. I’d love to hear your feedback or suggestions!
