The service looks interesting, but I'm wondering if there's a technical reason why it's a SaaS. CSVs could be parsed entirely on the client, and it should be possible for .XLS/.XLSX as well. If not with pure JavaScript+Web Workers then surely with WebAssembly.
Doing this traditionally on the backend is fine of course, but as others have mentioned, trusting you with potentially sensitive data is a hurdle for many companies and individuals.
