I didn't count, but you make extensive use of the Random() function.
Could that be the cause of slowness?
No, Random() is called only while records are populated - this step is

Trying to extend the import/export example of fpspreadsheet from a dBase

You need to check common cases, not uncommon cases like generating a

An empty cell occupies only a nil pointer.
It may sum up, though, if the table is large and sparsely populated.

Amazing. I tried the AVLTree used by fpspreadsheet and it needs 0.37 sec
