Do you use the library called OpenCSV? With this library generate any csv file is more easy.

So, because the excel and scientific notation i needed put one equals(=) before the some values.

Using the annotation @CSVBindByName it’s possible with attribute called format.

@CSVBindByName(format = "=%s")
I had to read the case test of documentation to find any example of use this attribute, but, nice!
and that’s all folks!
