Respected sir,
Let me just start this message by thanking you for all the noble work you have been doing for learner’s like us. Your work of automation has really simplified my work and saved more of my productive time.
Need a help from you sir. At my work in a day I get around 100 to 200 pdf files which needs to be merged in a set of 3 pdf files into one which really takes a lot of my productive time. So I was thinking if you could possibly help me with a macro for merging the same in one go. For instance I will be saving pdf files in the format of 1.pdf 2.pdf 3.pdf 4.pdf 5.pdf 6.pdf. Now here the macro would work on the constrain of 3 that I provide to it. And it would merge that 1.pdf+2.pdf+3.pdf and give me and output in other folder as 1.pdf/test1.pdf and on the loop it will merge 4.pdf+5.pdf+6.pdf and give output as 2.pdf/test2.pdf and so on it will run the process until the last set is completed and on completion it would give a message box of completion.
Is this possible with excel via sir. Really looking forward to your response sir. Would be really very Greatfull to you for this as it would really save a lot of my productive time sir. Please please help me in this.
