Excel is spreadsheet application. It is not related to the parent post, which discusses networked CRUD application, with various integration points, DB, caching, redundant deployments, etc..

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.

lol, HN melodrama-purists downvoting

No, Excel is not relevant to the conversation. Excel is a standalone desktop application. No, Excel is not an example of a "no-code" webapp. Do you seriously need another adult to tell you these things?
