CSV ↔ JSON running in Hexkit

// overview

What it does

CSV ↔ JSON is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Convert CSV rows to JSON arrays of objects (and back), header-aware.

Because Hexkit is a native app rather than a web page, anything you paste into the csv ↔ json stays local — there are no uploads, no accounts and no telemetry. You can reshape configs and API payloads even with the network turned off, which makes it safe for tokens, keys and production data.
