Useful Tools & Suggestions:

If you’re converting newlines to commas, Convert Column to Comma is another useful one especially when your data is in a strict vertical format. And if there’s junk in between, like gaps or extra returns, Remove Empty Lines helps clean it out before the merge. It’s a smooth way to go from multi-line lists to a tight, inline format for CSVs, JSON, or quick copy-paste tasks.
