Look at the beginning of spm_eeg_convert. There are some default
parameters set there. The one that you need is called 'inputformat'.
Beware that if you change that SPM won't detect other formats
correctly.
You can also make a script by exporting the history from a processed
file using the reviewing tool. Then you can modify that script to
process other files.
