Hi @lwx228,
One resource within JMP that is very helpful is the Scripting Index platform under Help.
You'll want to use the Save As on your data table. After you've opened it and done whatever you want to it, you would do something like:
dt << Save As("Filepath\filename.xlsx")
You can have all sorts of extensions, csv, txt, etc. It then saves it according to the extension.
You can even create an Excel workbook with somethign like:
Create Excel Workbook("filepath\filename.xlsx",{"data table name 1", "data table name 2"}, {"Worksheet name 1", "Worksheet name 2"})
It sounds like what you want to do is something more like the last option.
Hope this helps!,
DS
