Add Line Numbers to Text
Add line numbers to multi-line text with customizable format, alignment, and position
Tool Introduction
Feature Overview
Add line numbers to multi-line text. You can customize the line number format, alignment, and whether they appear at the beginning or end of lines.
Typical Scenarios
- Add line numbers to multi-line code for precise reference during review or discussion.
- Add line numbers to logs or configuration files to quickly locate and debug issues.
- Show code snippets with line numbers in technical articles or tutorials for better readability.
- Add line numbers to multi-line API responses to compare, record, or annotate data.
Usage Tips
- Format and clean up the text before adding line numbers so the result is easier to read.
- Use zero padding for line numbers in large files to keep numbers visually aligned.
- Line numbers at the beginning of lines are better for explanations; at the end preserve original indentation.
- For text with many blank lines, choose whether to skip blanks based on how you plan to reference lines.
