Parse User Pasted Text and use in SQL query

Question

I am trying to take some user pasted text (typically would come from Excel) and parse those values and put into a query.
text area:
":P11_text"
query:
"select *
from table
where column in :P11_text;"
I have tried some variations of replace and translate in order to parse that list of values...something like: translate(:P11_text, chr(10)||chr(13), ',' ).....and many variations of this.
I have been able to replace the end of lines with the commas, but it appears that I am not getting my single quotes captured, even when trying to force them in. The best attempt returned single quotes and commas in between values but not at the beginning and end of the list of values.
I would bet that there is an easy way to accomplish this or an easy way to accomplish the requirement in a different way altogether.
Please point me in the right direction.

I finally got this one figured out!
create or replace type myTableType as table
of varchar2(4000)
create or replace
function in_list( p_string in varchar2 ) return myTableType
as
l_string long default p_string || ',';
l_data myTableType := myTableType();
n number;
begin
loop
exit when l_string is null;
n := instr( l_string, ',' );
l_data.extend;
l_data(l_data.count) :=
ltrim( rtrim( substr( l_string, 1, n-1 ) ) );
l_string := substr( l_string, n+1 );
end loop;
return l_data;
end;
--The SQL Query is:
select *
from t wher c in (select *
from THE
( select cast( in_list(translate(:p10_prolist,chr(10)||chr(13),',')) as
mytableType ) from dual ) a);
