How it works

Each non-blank line receives the next number in sequence, optionally zero-padded to the width of the largest number so everything stays aligned in monospaced output.

Frequently asked questions

Can I start from zero?

Yes. Set the start value to 0 or any other number, including negatives.

Will it renumber an existing list?

It prefixes new numbers; remove old ones first with the find-and-replace tool.
