Add Line Numbers

Add sequential numbers to pasted text lines. Choose the first number and a literal separator to prepare notes, checklists or numbered examples.

Start a sequence

Set Start at to 1 and keep the default period-space separator to make a conventional numbered list.

Continue existing notes

Start at 21 to continue a previous twenty-item list. Numbering increases by one for every input line.

Handle blank entries

An empty line still consumes one number. Remove blank lines with Clean Text Whitespace beforehand if they should not count.

Choose a copy format

Replace the separator with a colon, a closing bracket or a tab to match the destination document. Existing numbers are retained as text.

Add Line Numbers FAQs

No. Existing prefixes remain part of each line, so clean them before applying a new sequence.
Enter 0 as the starting value; the first three lines receive 0, 1 and 2.
