Line Numberer
Add line numbers with control over the starting number, separator and padding.
Numbered lines, your way
When plain sequential numbers are not quite enough, this gives you the controls: start the count from any number, choose what sits between the number and the line — a dot, a bracket, a colon, a tab — and pad the numbers so they line up in a neat column. It turns a block of text into a properly numbered list formatted the way you want.
Paste the text, set the options, and each line is numbered to match.
When the formatting matters
The control pays off when the numbering has to fit a specific style: continuing a list that started at 100, matching a legal or reference format, aligning numbers so a two-digit and a three-digit line still line up down the left edge. For a quick, plain numbering you do not need all that — the simple line number tool covers it — but when the format is fixed, these options get it exactly right.
Frequently asked questions
Can I start numbering from a number other than one?
Yes — set any starting number, which is handy for continuing a list.
Can I change the separator and padding?
Yes — choose what goes between the number and the line, and pad the numbers so they align.
Is my text uploaded?
