I'm experiencing the same problem. Strings are being truncated at around 153 characters.I suspect the problem is occuring here: https://github.com/mongodb/mongo/blob/master/src/mongo/tools/export.cpp#L94From my understanding of the code, the toString() function defaults to not "full", so the full parameter should be set to true as follows:return csvEscape(object.toString(false, true), true);Could someone please confirm this is the case?Thanks,Josh
