Combining Documents is causing issues with Formatting

Hi Experts,

I am trying to combine multiple documents (some .docx and some .xlsx) together and once this job is done, the converter just changes the formatting, total number of pages increases from 28-30 to 100+.

Overall formatting changes, and pages print on multiple pages causing a total different look to the document. On the know issues, I saw that having Adobe reader and Adobe Acrobat Pro bot installed together can have issue, but that has been mitigated.

Please help.

Thanks!!!
