How to use this tool

  1. Enter source text, first line number, last line number.
  2. Select Update result to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Normalize line endings to LF and number lines starting at one. Return the inclusive slice from first through last; reject ranges beyond the available lines.

A WORKED EXAMPLE

Using source text = First line Second line Third line Fourth line, first line number = 2, last line number = 3, the result is Second line Third line. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

Yes. Selecting 2 through 3 returns both line 2 and line 3. Soft wrapping on screen does not create additional numbered lines.

What to keep in mind

A final newline creates a final empty line. This tool counts lines, not sentences or displayed soft wraps.

Common questions

Are the first and last lines included?
