    I did a quick test and this is actually an Excel data representation issue. If you create a CSV file including the following three lines:

    id
    802334127760489980
    624764543663741950

     

     

    and open it in Excel then it will show it as

    id
    802334127760489000
    624764543663741000

    Tested with Excel 2016 for Mac.

    Is your excel column using Rounding?

    Thanks. Below is the XML code and I've attached part of the excel file.

    Hi Thomas, I don't think the numbers are rounded in the excel file. I'm guessing the number is out of the range of the Rapidminer's "real number type"? Any idea how to fix the problem? Thanks a lot.
