My output has an extra empty object at the end

you have a trailing newline in your CSV. Delete the last blank line and re-paste.

Fields are showing as strings but I need numbers

CSV doesn't have types. You'll need to post-process the JSON. In JavaScript: `data.map(row => ({ ...row, age: Number(row.age) }))`.

your header row probably has extra spaces or inconsistent casing. Check for `name ` vs `name` or `Name` vs `name`.

that field needs to be wrapped in double quotes in your source CSV. Go back and fix the raw data first.
