I found it was caused by the foreground color.
block it





block it:
   Dim titleStyle As PoiCellStyle
    titleStyle.Initialize(wb)
    titleStyle.BorderBottom = titleStyle.BORDER_THIN
    'titleStyle.ForegroundColor = fx.Colors.Green.As(Int)
 
    titleStyle.HorizontalAlignment = titleStyle.HORIZONTAL_CENTER

I changed it to this, but it didn't work

B4X:
titleStyle.ForegroundColor = xui.Color_Blue

Is there any way? Can use color on excel 2003.thank you all

I see this line
  • Supports both xls and xlsx (Excel 2007+ format). jExcel only supports the old format.
Also can only try Excel 2007

Currently there is only Excel 2003 version, so learn from JPOI first,

jPOI 5 + XLUtils . I checked the code, default Excel 2007, Requires Excel 2007 to be installed,If I need them, I need to install Excel 2007.. Thanks,Erel

I'm sorry to say but everything written here is wrong.

jPOI5 + XLUtils work with the old Excel 2003 format.
You don't need Excel to be installed.
