About the Line Numbering Tool

The Line Numbering Tool prepends a sequential number and a configurable separator to the beginning of every line in your input. You can set any positive integer as the starting number, which is useful when continuing an existing numbered list or when splitting a long document across pages. Four separator formats are available: period-space ("1. Text"), parenthesis-space ("1) Text"), dash ("1 - Text"), and colon ("1: Text"). Every line receives a number, including blank lines, ensuring consistent alignment when the output is pasted into a document. Common use cases include numbering the steps in a how-to guide, adding line references to code snippets shared in code reviews, creating numbered agendas for meetings, and preparing legal documents where each clause must be sequentially identified.

Can I start from a number other than 1?

Yes — enter any positive integer as the start number. This is useful when continuing an existing numbered list or when your list starts at a different point.

Does it number blank lines?

Yes — every line in the input (including blank lines) gets a sequential number. This preserves the alignment of your content.

What separator formats are available?

Four formats: "1. Text" (period-space), "1) Text" (parenthesis-space), "1 - Text" (space-dash-space), and "1: Text" (colon-space). Choose whichever fits your document style.
