Doesn't handle wildcards/multiple inputs

If you run te2a3 with a * it only processes the first .textexpander file

That's true, but it's not something I plan on changing, because it's not really worth the effort, sorry.

You could try to use a bash loop to convert each file:

for i in *; do te2a3 "$i"; done
