Populate Data Source with Tab Text file

Hi all,

As I know to populate a data source (I use the command append) I need a list of list.
I start from a tab text file that must be converted to a list of list with standard routine: I read tab text file from disk using delimiter and after for each record I split it into columns using “my” feature to speed up the conversion using property variable.
There is a trick or workaround to populate a data source “directly” with a tab text file (example 10000 records for 6 columns)?
Or maybe a Call Method to convert more faster a tab text file in AppleScript List of list?
