Your two sides scenario tallies with my own, except I'd imagine they're not usually part of the same company (but other people will have different use cases, of course). In your example, you could absolutely use an existing CSV or XLS parser to do this. The problem is that you're now responsible for making sure that you've got the latest data, have parsed it, and have imported it. As a developer, Sheetlabs allows you to put the onus back on the data publisher to ensure that they're giving you the latest data. Plus it's in an easier to consume format too!
