Useful Tools & Suggestions:

If you’re adjusting list length, Truncate a List is great when you need to cut things down to a specific size fast. And if you’re expanding instead of trimming, Right-pad a List can help keep the formatting consistent as you add space or filler. Whether you’re prepping a dataset, formatting output for code, or just keeping things tidy, those tools make it way easier to hit your target length without manual cleanup.
