This is amazing, but there is no way that my firm will send any excels with our data to a relatively small and unknown third-party provider who will host it on a public URL. Are you thinking about allowing users to run this on-site?
I was about to say the same. I'd pay for a license to use a self-hosted version.
Sheetjs.com seems in the same space and you can self host.
you need a dev to make that work.
I guess OP value is "no dev needed"
That's true, though the things in the demos directory would simplify that.
This is a valid concern that people have shared with me before. It isn't in my immediate plans yet but depending on more feedback, we might offer an on-site solution in the future.
