Plain Text to Google Sheets

I have a block of plain text where every entry sits on its own line. Your job is to move that data into a Google Sheets document laid out in exactly 10 columns.

The source file will arrive as a simple .txt file—no commas, tabs, or other delimiters beyond its line breaks—so you’ll need to decide the most efficient way to distribute those lines across the ten-column layout (array formulas, split functions, scripts, or a quick import wizard; whichever gets the cleanest result).

Deliverable: a shareable Google Sheet with all rows neatly filled, ready for me to review and start using right away.
