How is the delimiter detected?

Auto-mode counts tabs, commas, pipes, and semicolons on the first non-empty line and picks the most common one. For mixed data, pick the delimiter explicitly.

Does sorting handle numbers?

Yes — when both sides of a comparison are numeric, the sort uses numeric ordering. Mixed or non-numeric columns fall back to localeCompare.

Is the file uploaded?

No. Parsing and sorting happen in the browser. Even Load file just reads the file locally via FileReader.

What's the row limit?

Bound by browser memory. Tens of thousands of small rows render smoothly; millions may be slow because the table renders all rows.
