need a softeware that should works as print merge from COREL DRAW or mail merge from MS WORD.

Need a software that works like print merge. As I am currently using COREL DRAW, but it takes lot time to convert it to pdf. Faster solution is MS WORD mail merge but it is not fluid as COREL DRAW.
The COREL DRAW takes around 1 and half hour for 2800 pages to completly merge the .csv or .txt(tab delimited) file to design and again convert it into pdf. For processing 2800 pages twice, first merging then exporting to pdf will consume my whole 256 GB of RAM.
where as
The MS WORD takes around 5 min and can works on 4 GB RAM pc but with some less fluedity.
