Macro inputs from text file to draw nodes at x,y where x,y values are read from the file
I am drawing boxes using a macro like
newcommand{drawbox}[2]{
node[box, fill=green] at (#1,#2){};
}
where I specify the arguments #1 and #2 (that correspond to x,y values) when calling the macro.
Now I need to draw multiple boxes where values of the arguments #1 and #2 are in a column in a text file. I probably need a for loop but how can I read each line of the text file to get arguments #1 and #2?

A possible solution with datatool
documentclass[border = 5pt]{standalone}
usepackage{tikz}
usepackage{datatool}
DTLloaddb{coordinates}{points.csv}
newcommand{drawbox}[2]{
node[draw, fill=green] at (#1,#2){};
}
begin{document}
begin{tikzpicture}
DTLforeach*{coordinates}{x=x,y=y}{%
drawbox{x}{y}
}
end{tikzpicture}
end{document}
where points.csv has the structure
x,y
1,2
3,4
5,6
EDIT
A slightly modified version of your code, just to showcase the things you can do with this
documentclass[border = 5pt]{standalone}
usepackage{tikz}
usepackage{datatool}
DTLloaddb{coordinates}{points.csv}
begin{document}
begin{tikzpicture}[
box/.style={
draw,
fill = green,
minimum width = 2cm,
minimum height = 1cm,
label = center:#1,
opacity = 0.2
}
]
DTLforeach*{coordinates}{x=x,y=y,text=text}{%
node[box=text] (theDTLrowi) at (x, y){};
}
draw[red, ->] (1) to (2);
draw[red, ->] (2) to (3);
end{tikzpicture}
end{document}
In this case the input file is
x,y,text
1,2,foo
3,4,var
5,6,baz
