We are facing a issue when we are trying to convert an excel file with below
values to csv file.

Cell value : 3E-104
5E-104
5E-106

All the above values are getting converted to 0 , in a csv . Cell format in MS
Excel is 'General'

Java code used for the conversion

DataFormatter formatter = new DataFormatter(true);
String fmtCellValue = formatter.formatCellValue(cell);

I am attaching the sample of excel file.

Versions tested : POI - 3.9, 3.10-Final, 3.10.1, 3.11-beta3

Can you post your code? Preferrably as simple unit-test, so we can reproduce. I
tried quickly, but could not reproduce your problem with the sample file given.

I could reproduce it now, FYI, POI internally does the following, which fails
for such small numbers:

        DecimalFormat format = new DecimalFormat("#.##########", new
DecimalFormatSymbols(Locale.getDefault()));
        double d = 3.0E-104;

        assertEquals("3.0E-104", format.format(d));
