You've probably already realized that →STR will help you out with this conversion. Note that it's not a 100% safe conversion, though. →STR will convert objects into strings which are similar to the object's representation when recalled to the stack, which doesn't necessarily contain an exact copy of the underlying data.

Some objects stored on your calculator may not have an exact "text equivalent". In those cases, you may find that →STR creates placeholders for the parts it can't directly convert.

Back in this thread, we discussed another issue that you might run into with this. In particular, the names of objects on the calculator may not be compatible with the SD card's file system, so you might run into trouble saving the files. I also recall finding that I would run into sporadic "invalid DOS name" errors when attempting to copy objects to the SD card, even when there was no compatibility issue with the name in question. But that may have been isolated to some sort of file system corruption on the SD card (see the thread I referenced). I never was able to find a sequence of steps that would recreate those errors, though.
