I imported an xlsx file to an empty table. The imported values of a column in the table are starts with "x000D" value, but in the original xlsx file these are new lines.
Running this query and exporting it to an XLSX file:
select EMPNO, CHR(13) || CHR(10) || ENAME as ename, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO
from emp
Importing that file back into the table
...but after that the table looked as I expected, with an actual line feed. I also tried with just CHR(13) instead of CHR(13) || CHR(10).
