获取此applescript代码的javascript版本

Question

我想获取此代码的javascript版本。但是我失败了。

我不知道如何在javascript中表达“导出到文件exportName”。

调用导出方法时，我总是遇到类型错误。

tell application "Numbers"

    set theFilePath to POSIX file ("/Users/cong/Desktop/")
    set exportName to (theFilePath as text) & "test1.xlsx"

    open POSIX file "/Users/cong/Desktop/test1.csv"
    tell front document
        export to file exportName as Microsoft Excel
        close
    end tell
end tell
