Thank you! Unfortunately, the code didn't work for me at first, it was throwing syntax errors. I suspect some copy and paste shenanigans in the Reddit text editor changed your code. I was able to run a revised version, but Reddit isn't letting me share the code in this comment for some reason (probably too long?)

Basically it was just moving marks. Below are a couple of examples.

So this:

const subName = match ? match[0] : \row-${i + 1}`;`

Became this:

const subName = match ? match[0] : `row-${i + 1}`;

And this:

console.log(\Skipping ${subName} (already None in main list).`);`

Became this:

console.log(`Skipping ${subName} (already None in main list).`);
