             Summary: Investigate use of org.apache.poi.ss.usermodel.DataFormatter in Excel translator
                 Key: TEIID-4995
                 URL: https://issues.jboss.org/browse/TEIID-4995
             Project: Teiid
          Issue Type: Enhancement
          Components: Misc. Connectors
    Affects Versions: 9.2.4, 8.12.11.6_3, 8.7.12.6_2
         Environment: Excel translator
Integer values in string columns
            Reporter: Marc Shirley
            Assignee: Steven Hawkins


For integer values in a string column, values are displayed as a decimal value (for example, a value "5" is displayed as "5.0").  It looks like org.apache.poi.ss.usermodel.DataFormatter [1] by default attempts to format values in the same manner as Excel would display it [2], and would result in the integer value "5" being displayed as "5".  In the case of string columns, this would avoid the user needing to modify source data to compensate as indicated as workarounds in TEIID-3947.

[2] The default number format will mimic the Excel General format: "#" for whole numbers and "#.##########" for decimal numbers.
