About Column Types

Column Types was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Processing runs locally in your browser using modern Web APIs. Nothing is uploaded, nothing is logged, and there is no quota to worry about for casual use. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
