No, I just mean some program that converts output made by other programs to the internal format used by openRPGmaker. No need to reinvent the wheel.
On a similar note, there are people developping complete map editors with gui for old games (example : Aridia for PS3). Great, but it's so much easier to just write a converter from ROM format to TMX format, edit TMX with Tiled, then insert back in the ROM with another converter (I did this with PS3 precisely, when Aridia didn't handle maps, I believe it's the case now).
Often, the project involves so much work just in the GUI part that it's left unfinished (Aridia is a bad example in this sens, the program is great and functional).
