In the files, each layout box is separated by a newline. And each paper is separated by two newlines
The data structure of each layout box is as follows : "Unique code"(\t)"Metadata label"(\t)"Text"(\t)"x0 value "(\s)"y0 value"(\s)"x1value"(\s)"y1value"(\s)"width value" (\s)"height value"(\s)"font size"
