How to create table in sqlite with changing number of colums

I am dealing with many excel files which i want to port into csv

i know how to do this for each file if i know the number of columns to create.  But is there a way to do so without knowing? 

for example instead of  _SQLite_SQLiteExe($sDatabaseFile, "CREATE TABLE test (test, test2, test3, test4);", $sOutputFile)

can i do _SQLite_SQLiteExe($sDatabaseFile, "CREATE TABLE test ($aArray1);", $sOutputFile)

thank in advance
