Answer 1

It doesn't work that way with PDF. You find a plugin that can read it, study it. But in essence, all the work there is reduced to

ДайМнеСимволыИзПрямоугольникаСКоординатами(100, 50, 140, 30);

Those. works great with documents where only the numbers in the columns change and you just calculate its position once. If every time you need to look for a string that you don’t understand where it can appear, then everything is not so rosy.
