We have APEX 4.2. We have created Interactive report on a table. When we download that report to csv, everything is fine except for loan number which is a varchar2(50 Byte) (e.g. 210568900000000012). It is shown as 2.10569E+15. When we try to format the cell as text, it rounds off the number (e.g 210568900000000000).
I encountered this issue previously, but regarding leading zeroes. It was really a battle with Excel - not APEX.
Although I'd be interested to see if anyone has found a workaround that made Excel interpret it as a character instead of a number. We tried a few leads but to no avail.
