In my experience, most businesses are running some portion of their operations in spreadsheets.
More importantly: they don't want to change. They're running things out of spreadsheets because that represents the technical skills their staff has. They don't want to learn a new, specialized tool for a process when a spreadsheet works. They don't want to pay for that specialized tool. They don't want to deal with troubleshooting it when it fails.
