Good morning!
Yes tile tag data can be exported from CharPad Pro although currently only in the form of an asm/text file...
File >> Import/Export >> Text/Asm >> Export Tile Set (and attributes)
If it would be more convenient to have the data as a raw binary file then you could just trim out the tile data section in that file, assemble it and trim off the first two bytes of the resulting PRG file (the load address).
A binary export option might be useful though I guess, I will add it to the todo list.
