import { PdfReader } from "pdfreader";
new PdfReader().parseFileItems("./GeM-Bidding-3342395.pdf", (err, item) => {
if (err) console.error("error:", err);
else if (!item) console.warn("end of file");
else if (item.text) console.log(item.text);
});

From any OS console system (Linux Mac Windows) the easiest way to parse a PDF is to use either of the utility commands pdftotext - Xpdf or Poppler (generally 64 bit) Windows binary here
To export say two pages to console use pdftotext -nopgbrk -f 1 -l 2 GeM-Bidding-3342395.pdf -
To save in a file use a filename in place of - or pipe to another command
The sequence of output can vary depending on options so the above without mod looks like this:-
However if I add -layout in the poppler version its more like this:-
And there are other options in the Xpdf version such as -table -simple -simple2, so you need to pick the one best suited to your desire.
