What it does

Adds a sequence number in front of each line.

Options

  • Start and Step: for example, start at 10 and count by 10 (10, 20, 30…). Negative numbers work too.
  • Format: the number goes where {n} appears. Use any pattern you like, such as {n}. , {n}) , [{n}] or No.{n}\t. If you leave out {n}, the number is placed in front of the format.
  • Pad with zeros: pads numbers to the width of the last number, as in 01, 02 … 10. Useful for file names or codes that need to sort correctly.
  • Skip blank lines: on by default, so blank lines get no number and do not use one up.

When to use it

Use it to number a presentation order, a checklist or a participant list, or to prepare code review material that needs line numbers. To number after sorting, place it after Sort.

To renumber lines that already have numbers, add Remove line numbers and bullets in an earlier step to remove the existing numbers first.
