Split Cell Contents To New Rows?

I'm trying to split the contents of a cell to a new row (with data from other columns on the row copying across) below the originating cells row. Most of the split cell macro posts I've seen split the contents to a new row at the bottom of a range, however I'm looking to split the contents to a new row directly beneath the original row where data will already exist. I don't want to copy over this data I just want to push the data down depending on the number of rows created.

The contents in the cell being split can vary (1:n), so the number of rows needed to be inserted depends on the count. The majority of the contents in the cell is separated by a line feed (Alt Enter) but some may be separated by a tab or comma.

Essentially what I'm trying to achieve is something from this
A
B
C
D
