How to use macro as a `foreach` range?

These two loops do not produce the same result:

\documentclass{article}

\usepackage{tikz}

\begin{document}

\foreach \i in {a,b,c} {%
    \i+
}

\def\Index{a,b,c}
\foreach \i in {\Index} {%
    \i+
}

\end{document}

Why is this? How do I get \foreach to iterate over the comma-separated content of \Index even though it looks like a single token?

Look at https://tex.stackexchange.com/q/12091/1952 and replace \foreach \i in {\Index} by \foreach \i in \Index – Ignasi Oct 15 '19 at 14:20
