TOOLNumber your lines in one click
Turn a plain list into a numbered one. This tool prefixes every line with a number — pick the starting value, the separator (a dot, bracket, colon, tab or space), and whether to skip blank lines. Handy for making ordered lists, referencing lines, or numbering steps.

Frequently asked questions
How do I add numbers to each line?
Paste your text and the tool prefixes each line with a number. You can set the starting number and choose the separator between the number and the line.
Can I start numbering from a different value?
Yes. Set any starting number — for example 0 or 100 — and the lines are numbered upward from there.
Can I skip blank lines?
Yes. Turn on skip blank lines and empty lines are left unnumbered so only lines with content get a number.
