I've experienced Excel being used with all of those in bigger non-tech companies. Integration points: Everyone sends their version to Person A, and they integrate it, filter it, postprocess it, extracts parts into another sheet, etc. Caching: Everyone has their own version of the excel sheet in their local inbox. Redundant: There's typically plenty of shared directories on which you can find the same excel sheet in different versions.
