Are they all similar sizes?
Because if so then making them all exportable essentially at once (or in 100 presses rather than 500) and then firing them through something like irfanview batch mode helps more.
That said I don't know. I tend not to make sprite sheets or anything like that (I am usually more interested in editing something than exporting it, and if I did care then most times the VRAM viewers or simple tile viewers once set up properly do what I need) so tend not to look at command line options for it all, and if this is going to be something more exotic like 8bpp GBA format (most older tile editors I would expect to use for this tend to top out at 4bpp GBA if you are lucky) in a large tile format (graphical tile viewers are hard enough to find doing that) then that gets even more fun.
If you figured out the pointers (or at least how large each sprite is) and have a command line program you could probably slice it up and fire it through with the relevant options.
