Paste clipboard (stamp) as TEXT

I occasionally like to add "machine-tape" reconciliations to my pdf pages. Currently I do it with copying it to clipboard from Excel and then pasting via a stamp. However, this pastes an image. Is there a way to paste the text? The only way I could think of is by using a command line app called cpdf to merge the machine tape (exported to pdf) with the extracted original page (as the background) and then replacing the original page in the pdf file with the merged pdf file. That method does what I want and works fairly reliably, except for a few issues. Is there a way to either do this using an existing acrobat function or to script it in JS?
