Export an expression to a byte array representing an XLS file:
bytes = ExportByteArray[{{1, 2}, {3, 4}, {5, 6}}, "XLS"]Check the format of the byte array:
ByteArrayFormat[bytes]Import the data from the byte array:
ImportByteArray[bytes]Write the bytes to an XLS file:
BinaryWrite["file.xls", bytes];
