our uncle Skip is frustrated because he can't find "split into rows." What's the problem?

Select an answer:

There are no delimiters to split by$.$ Thus, this option isn't available.

In the Split Column by Delimiter dialog box, he needs to click Advanced Options to expand that section.

The column has too many different delimiters. Thus, Split into Rows isn't available.

He didn't check the box to expand See Advanced Options.
