Oracle: Comma Separated String To Rows 10g Onwards

One simple way for single string
with t as
(select '01,05,10,15,20,25,30,35,50,75,23,03,04,00,00,00,00,00' txt from dual)
select regexp_substr ( txt, '[^,]+', 1, level) data from t CONNECT BY level <= length (txt) - length (replace (txt, ',')) + 1

For Multiple Rows with comma Separated values:
with mytable as
(
    select 'nimish' col,  '1,2,3,4,5' txt from dual
    union
    select 'garg' col,  '6,7,8,9' txt from dual
)
select    
    mytable.col,  
    regexp_substr ( mytable.txt, '[^,]+', 1, n) as num
from  
    mytable,
    (
        select  
            level n
        from  
            (
                select
                    max ( length (txt) - length (replace (txt, ',')))    as max_commas
                from  
                    mytable

            )
        connect by level <= 1 + max_commas
    ) ctr
where
    ctr.n    <= 1 + length (txt) - length (replace (txt, ','))
order by
    mytable.col,
    ctr.n
