How to force save_as to use different file_type than the extension.

[rgacote]

Need to write to an intermediate filename with a non-csv extension.
Example code:
pyexcel.save_as( array=rows, dest_file_name=filename.csv.prg, encoding="utf-8", dialect="excel" ) os.rename(progress_path, export_path)
Tried adding dest_file_type argument, but that looks to only work when I write to memory.
Is there a way to tell save_as this is a .csv file even though the extension is not .csv?

yes, dest_file_type works only when the destination is a stream. I am afraid that pyexcel cannot do that ATM.

Let me think about it. It should not be a rocket science to get it supported. Your use case is symmetric to force file type on read: #148

example usage:

    def test_force_file_type(self):
        pe.save_as(array=[[1, 2]], dest_file_name="a.txt",
                   dest_force_file_type='csv')
        actual = pe.get_array(file_name="a.txt", force_file_type="csv")
        eq_([[1, 2]], actual)
        os.unlink("a.txt")

    def test_force_file_type_for_save_book_as(self):
        pe.save_as(bookdict={"sheet1": [[1, 2]]}, dest_file_name="a.bin",
                   dest_force_file_type='xls')
        actual = pe.get_book_dict(file_name="a.bin", force_file_type="xls")
        eq_({"sheet1": [[1, 2]]}, actual)
        os.unlink("a.bin")
