nodejs lib for extracting data from PDF files

pdf.js-extract

extracts text from PDF files

This is just a library packaged out of the examples for usage of pdf.js with nodejs.

It reads a pdf file and exports all pages & texts with coordinates. This can be e.g. used to extract structured table data.

This package includes a single file build of pdf.js, so it does not depend on other npm packages any more.

Note: NO OCR!

Install

		console.log(data);
	});
