Frequently Asked Questions

What numbering formats are available?

You can choose from several formats: 1. Line (dot), [1] Line (bracket), (1) Line (parentheses), 1: Line (colon), and 1 - Line (dash). Each formats the number differently.

Can I customize the starting number and increment?

Yes, you can set any starting number and increment value. For example, start at 100 with an increment of 5 will number lines as 100, 105, 110, etc.

What happens to empty lines?

Empty lines will still get numbers in the sequence but will contain no text after the number prefix. The numbering continues based on the increment regardless of line content.

Can this be used for code files?

Yes, this is perfect for adding line numbers to code files before printing or sharing. However, for actual code editing, consider using an editor with built-in line numbering.
