I am trying to compare two PDF reports irrelevant of the actual data. I am more interested to ensure the coordinates of the data between the two reports are identical. is there a way to exclude the difference of data between two PDF reports using the pdfCompare library?

You can define areas of your document, that should be excluded from the comparison. Check out exclusions in the README. Some Background: PdfCompare renders PDF pages to images and does a pixel by pixel compare. All you can do is exclude rectangular areas from the comparison.
