How the line numbering works

  1. Step onePaste your text. Each line break starts a new line.
  2. Step twoChoose the first number, the text between the number and the line, and whether to pad the numbers.
  3. Step threeCopy the numbered text from the result box.

What this tool does not do

  • It numbers lines as they are broken in the box; it does not wrap long lines for you.
  • It does not make a real numbered list with indentation, as a word processor does.
  • It adds the numbers to the text only; it does not remove numbers that are already there.

Frequently asked questions

Can the numbering start at 0?

Yes. Type 0 in the first number box. Whole numbers from 0 to 999,999,999 are accepted.

What does padding do?

Padding gives every number the same width so the lines stay lined up: spaces on the left ( 9, 10) or zeros (09, 10).

Are empty lines numbered?

Not by default, so the numbers follow your real lines. Untick the box to number empty lines too.
