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
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.
