OP definitely needs to elaborate for a better answer, but I've seen this kind of CSV-ish structure used once or twice to define something like a tree structure (not that it's a great idea, more there was a CSV hammer and hence . . .).

Edit: Just to be slightly more concrete, they had something like this YAML

--- Top A: - A1 - A2: - A2.1 - A2.2 Top B: - B1: - B1.1 - B1.2

And they represented as something like:

Top A, Top A,A1, Top A,A2, Top A,A2,A2.1 Top A,A2,A2.2 Top B, Top B,B1 Top B,B1,B1.1 Top B,B1,B1.2

The cake is a lie.
