I've successfully converted PDF's into workable formats for my job, and then used conditions to extract the correct data that I want. Literally converting a manual 45 minute job into a automatic 30 second job

To get the PDF into Excel, I firstly open the PDF, select all, and then copy and paste that into Excel. I then use Text to Columns (by spaces) to split all the data up into separate columns.
That should probably be a good start.

If this isn't what your looking for... Then I suggest you seek a paid program to do the job for you. Some are good and keep the same format once converted to xlsx.. but some are not. It depends on the PDF itself and the program that your using.
