The invention provides a data typesetting device comprising the following elements: a parameter parsing unit used for parsing a typesetting file so as to parse parameter information of fixed content and variable content in the typesetting file; a first file generation unit used for generating a first object file in a first format according to the parameter information of the fixed content; a second file generation unit used for generating a second object file in a second format according to the parameter information of the variable content, and used for re-generating the second object file according to changed parameter information of the variable content if the parameter information of the variable content is monitored to be changed. Correspondingly, the invention also provides a data typesetting method; the device and method can solve the problems in the prior art that typesetting parameter modification efficiency is low, thus improving typesetting parameter modification efficiency, and improving user experience.
