Line Numbering Tool

Easily Add or Remove Line Numbers from Text

Need to reference specific lines in a document, code snippet, or log file? Our free online Line Numbering Tool adds sequential numbers to the beginning of each line in your text. Customize the starting number, separator style, and padding. You can also easily remove existing line numbers.

Why Use Line Numbers?

• Code Readability: Essential for discussing, debugging, and referencing specific lines of code.
• Document Referencing: Makes it easy to point to specific lines in legal documents, manuscripts, or educational materials.
• Log Analysis: Helps in tracking and referencing events in log files.
• Collaboration: Facilitates clear communication when discussing specific parts of a text with others.
• Organization: Provides a clear structure to lists, instructions, or any sequential text.

Features of Our Line Numbering Tool:

• Add & Remove: Both add line numbers to plain text and remove them from already numbered text.
• Custom Start Number: Begin numbering from any integer (e.g., 0, 1, 100).
• Flexible Separators: Choose from common separators like colons, periods, pipes, dashes, arrows, or just spaces.
• Number Padding: Add leading zeros (e.g., 001, 010, 100) for uniform alignment.
• Empty Line Handling: Optionally skip numbering empty lines or include numbers for them.
• Instant Preview: The input text area updates directly with the numbered/cleaned text.
• Copy & Download: Easily copy the result or download it as a .txt file.
