Add Text to Each Line

What is Add Text to Each Line?

Add Text to Each Line is a text processing tool that appends constant or variable text to the beginning (prefix) or end (suffix) of each line in your text. This tool is particularly useful for formatting lists, preparing data for specific formats, adding line numbers, or creating structured content from plain text.

Why Use Add Text to Each Line?

Adding text to each line has several practical applications:

• List Formatting: Convert plain text lists into HTML, Markdown, or other formatted lists by adding appropriate markers
• Code Generation: Add prefixes like variable declarations or suffixes like semicolons to multiple lines of code
• Data Preparation: Format data for import into spreadsheets or databases by adding delimiters or field markers
• Line Numbering: Add sequential numbers to lines for reference or documentation purposes
• Comment Addition: Add comment symbols to multiple lines of code simultaneously
• URL Manipulation: Add domain prefixes or query parameters to lists of URLs
• Citation Formatting: Add consistent citation markers or formatting to bibliographic entries

Understanding Text Addition Options

Constant Text

Constant text addition applies the same text to every line in your input:

• Prefix: Text added to the beginning of each line
• Suffix: Text added to the end of each line

For example, adding the prefix "- " and suffix ";" to a list would transform:

Apple
Banana
Orange

Into:

- Apple;
- Banana;
- Orange;

Variable Text

Variable text changes for each line, allowing for dynamic content:

Line Numbers

Add sequential numbers to your lines with customizable options:

• Starting number (default: 1)
• Step value for incrementation (default: 1)
• Position (prefix or suffix)
• Separators before and after the number

Incremental Text

Add text with a pattern containing incrementing numbers:

• Text pattern with {n} placeholder for the number
• Starting number and step value
• Position (prefix or suffix)

Common Use Cases

Creating Formatted Lists

Convert plain text lists into various formatted lists:

• HTML Lists: Add "<li>" prefix and "</li>" suffix
• Markdown Lists: Add "- " or "* " prefix
• Numbered Lists: Add line numbers with a period

Code Manipulation

Efficiently modify multiple lines of code:

• Add comment symbols (// or #) to comment out blocks of code
• Add variable declarations (var, let, const) to lists of variable names
• Add semicolons or other syntax elements to the end of each line

Data Formatting

Prepare data for specific formats or systems:

• Add CSV delimiters or field markers
• Add SQL syntax elements (VALUES, INSERT, etc.)
• Add XML or JSON formatting elements
