methods for creating objects from file

I’m looking for information on using a file as an object creation source- Think converting a log file with 500,000 to 1,000,000 lines into a series of objects (1 per line) at regular intervals along a path.

No problem making a parser that can translate the log file into a list of object references. I just need the recommended method required for lumberyard to convert the list into objects.

Would someone please point me in the right direction?

If you mean place them in editor, you could use editor python scripting to do that. (View->Open View Pane -> Python Scripts)
