Generate insert statement using columns from all_tab_cols view

Question

i am trying to generate a dynamic insert statement using the columns for a table from the all_tab_cols view. if i do a select, i get the output as rows. How do i convert the row out to columns so that i get something like this : INSERT INTO TABLE_NAME (COL1, COL2, COL3,COL4.....) .
Any help will be appreciated!
