This is awesome, btw. Could you talk about how you came about the idea?
Thanks for the compliment. As a developer working on a lot of systems that integrate service coverage data I'm constantly being sent spreadsheets that contain zip code / postcode level information, and I need to import this into my database or my client's databases. And normally my apps only want to lookup one or two values per day - but the third party is sending me their entire 100MB spreadsheet, as they don't have an API to publish it via. It's time consuming, error prone, and clunky. But they don't have the skill or resources to create an API, so I'm hoping something like this might remove some barriers.
The publisher, who cannot / will not create an API from their spreadsheets, but would like to (either to ease their own pain, or because their end users are asking for it, or because they don't want to share their entire dataset so often).
The consumer, who wants to access a little bit of their publisher's data without having to import spreadsheets en-masse regularly.
The publisher is the customer of the service ultimately, but the consumer will quite likely be the one driving the publisher to adopt it. Being self-critical, I'd say this makes it a bit of a tough sell (you're one step removed from the actual customer).
