Tools needed in exporting file from .Pdf to word format

My boss has sent me a report I should work on via email in a .Pdf format. My report contains images, tables and word documents. I’m having trouble exporting the file to word format. Every time I export it to word format, the tables doesn’t seem to be recognized and it only gets converted to some square characters. The word documents' formatting also gets messed up, that I have to spend so much time editing it all over again. I need to finish my report on time. Is there any way that I could fix this as to save me time? Are there tools available that I could use? Can i convert pdf to word via internet?
