Adobe Acrobat is a great application, without doubt, but this doesn`t mean it can`t be improved. Sometimes a plug-in comes along, like this PDF Page Size Split, that adds new functions.
With PDF Page Size Split you can divide the pages that make up a PDF according to the size of the page you indicate; for example, fragment documents to be able to print them on A3 paper. You can also combine different sizes; for example the first 10 pages in A3 and the rest in A5 format.
Thus, it lets you export the reports to CSV format. If PDF Page Size Split is useful for you, you also have another version that can do batch processing: PDF Page Size Split Batch.
