Line Numbering

Number your lines

• Add Line Numbers — Number every line, starting from 1.
• Restart Line Numbers — Number every line, resetting back to 1 after each blank line.
• Custom Line Numbering — Choose your own starting number and step between lines.
• Number Every Nth Line — Only number every 5th (or Nth) line, leaving the rest untouched.
• Add Numbers to Selected Lines — Number only the exact lines you list, like 1,3,5-7.
• Renumber Text — Strip any existing numbering and start clean from 1.

Clean up or dress up

• Remove Line Numbers — Strip leading numbers like "1.", "2)", or "3:" from every line.
• Add Prefix to Lines — Add any text you choose to the start of every line.
• Add Suffix to Lines — Add any text you choose to the end of every line.
• Add Bullets to Lines — Turn every non-empty line into a bullet point.
