                    "=9", "=11", true, true, Clng(COLOR_RED)

' Export Excel file
response.write("Writing file: C:\Samples\Tutorial14 - conditional formatting in Excel.xlsx<br>")
workbook.easy_WriteXLSXFile("C:\Samples\Tutorial14 - conditional formatting in Excel.xlsx")

' Confirm export of Excel file
if workbook.easy_getError() = "" then
    response.write("File successfully created.")
    response.write("Error encountered: " + workbook.easy_getError())
end if

' Dispose memory

Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
