Quick Presets Explained

• Bullet List

Adds "- " prefix to each line creating markdown-style bullet list. Perfect for to-do lists, item lists, or unordered lists. Example: "- Item 1", "- Item 2", "- Item 3". Compatible with markdown editors.

1. Numbered List

Enables automatic line numbering with "1. " format. Each line gets sequential number (1. 2. 3. etc.). Customize start number if needed. Perfect for ordered lists, steps, instructions, or rankings.

"" Quotes

Wraps each line in double quotes. Prefix: """, Suffix: """. Creates "text" format. Essential for CSV files, string arrays, JSON data, or quoted lists. Example: "apple", "banana", "cherry".

[] Brackets

Wraps each line in square brackets. Prefix: "[", Suffix: "]". Creates [text] format. Useful for array notation, markdown links, tags, or structured data. Example: [item1], [item2], [item3].

() Parentheses

Wraps each line in parentheses. Prefix: "(", Suffix: ")". Creates (text) format. Good for function calls, mathematical expressions, notes, or grouping. Example: (value1), (value2), (value3).

`` Code Backticks

Wraps each line in backticks. Prefix: "`", Suffix: "`". Creates `text` format for inline code in markdown. Perfect for variable names, function names, or code snippets in documentation. Example: `variable`, `function()`, `class`.

Common Use Cases

Markdown List Creation: Convert plain text to markdown bullet lists (- prefix) or numbered lists (1. 2. 3.). Perfect for README files, documentation, or GitHub markdown.

CSV Data Formatting: Wrap text in quotes for CSV columns. Add commas as suffix. Create properly formatted CSV data from plain lists.

Code Generation: Add language-specific syntax. Examples: add "console.log(" prefix and ");" suffix for JavaScript logging, "print(" and ")" for Python.

SQL Query Building: Create bulk INSERT statements. Add "INSERT INTO table VALUES ('" prefix and "');" suffix to each line.

HTML List Formatting: Convert text to HTML lists. Add "

  • " prefix and "
  • " suffix for ordered/unordered lists.

    JSON Array Creation: Wrap items in quotes and add commas. Create JSON-compatible arrays from plain text lists.

    URL Processing: Add "https://" prefix to domain names. Add "/" suffix to URLs. Batch process URL lists.

    File Path Formatting: Add directory prefixes to filenames. Add extensions as suffix. Create full file paths from filenames.

    Perfect For

    • Software developers & programmers
    • Content writers & editors
    • Data analysts

    • Technical writers
    • Database administrators
    • SEO specialists
    • Office administrators
    • Students & researchers
    • Markdown users
    • Documentation writers
    • Anyone formatting text lists

    Skip Empty Lines Option

    When Enabled (Default): Empty lines remain empty without prefix/suffix. Preserves blank lines for spacing and readability. Useful when you want to format text but maintain paragraph breaks.

    When Disabled: Empty lines also get prefix/suffix. Creates lines with only prefix+suffix. Useful when you need consistent formatting on every line regardless of content.

    Best Practice: Keep enabled for document formatting. Disable for code generation where every line needs wrapping (quotes, brackets, etc.).

    Pro Tips for Prefix & Suffix

    • Use Quick Presets: Save time with one-click presets. Customize afterwards if needed. Presets configure both prefix and suffix.
    • Combine with Line Numbers: Use numbered preset or enable line numbering manually. Customize start number for specific needs.
    • Markdown Lists: Use "- " for bullets, "* " alternative, or enable numbering for ordered lists. Great for GitHub README files.
    • CSV Creation: Wrap in quotes (""), add comma suffix (","), copy to spreadsheet. Last line may need manual comma removal.
    • Code Wrapping: Add function calls or logging statements. Example: "console.log('" + "');" wraps each line in console.log.
    • HTML Lists: Add "<li>" and "</li>" for list items. Wrap output in <ul> or <ol> tags manually.
    • Swap for Multi-Step: Format once, swap to input, apply different formatting. Build complex formats step-by-step.
    • Special Characters: Use any Unicode characters. Emojis work too: "👉 " prefix creates emoji bullets.
    • Empty Line Control: Toggle "Skip Empty Lines" based on needs. Enable for documents, disable for data.
    • Copy Line-by-Line: For huge lists, process in chunks to avoid browser slowdown.

    Code Generation Examples

    JavaScript Console Logs: Prefix: "console.log('", Suffix: "');" - Wraps each line in console.log statement for debugging.

    Python Print Statements: Prefix: "print('", Suffix: "')" - Creates Python print statements from text lines.

    SQL INSERT Statements: Prefix: "INSERT INTO table VALUES ('", Suffix: "');" - Generates SQL insert statements.

    Array Initialization: Prefix: " '", Suffix: "'," - Creates string array elements with proper formatting.

    CSS Classes: Prefix: ".", Suffix: " " - Creates CSS class selectors from class names.

    HTML Links: Prefix: "<a href='", Suffix: "'>Link</a>" - Converts URLs to HTML anchor tags.

    Markdown Formatting Guide

    Unordered Lists: Use "- " or "* " as prefix. Creates markdown bullet points. Example: - Item creates bullet in markdown.

    Ordered Lists: Enable line numbering for "1. 2. 3." format. Markdown renders as numbered list automatically.

    Blockquotes: Use "> " as prefix. Creates quoted text in markdown. Good for citations or quotes.

    Code Blocks: Use "`" prefix and suffix for inline code. For code blocks, add "```" before/after entire text manually.

    Checkboxes: Use "- [ ] " for unchecked tasks, "- [x] " for completed. Creates interactive checkboxes in GitHub markdown.

    Headings: Use "# ", "## ", "### " as prefix for different heading levels (H1, H2, H3).

    Data Format Conversion

    Plain Text to CSV: Wrap in quotes (""), add comma suffix. Each line becomes CSV row. Import to Excel/Sheets.

    List to JSON Array: Wrap in quotes and brackets with presets. Add commas as suffix. Combine lines in JSON array format.

    URLs to HTML Links: Add "<a href='" prefix and "'>Link</a>" suffix. Convert URL list to clickable HTML links.

    Names to Email List: Add company email domain as suffix. Example: suffix "@company.com" converts names to emails.

    Filenames to Paths: Add directory prefix "C:/folder/" and extension suffix ".txt". Creates full file paths.

    Line Numbering Details

    How It Works: Adds sequential numbers before prefix. Format: "1. text", "2. text", "3. text". Numbers increment automatically.

    Custom Start Number: Default starts at 1. Change to start at 0 (0-based indexing), 100, or any number. Useful for continuing existing lists.

    Combine with Prefix/Suffix: Line numbers appear before prefix. Example with "- " prefix: "1. - item". Customize as needed.

    Empty Lines: Empty lines still get numbered unless "Skip Empty Lines" enabled. Control numbering behavior with skip option.

    Multi-Step Formatting

    Step 1: Apply first format (e.g., wrap in quotes). Result: "text".

    Step 2: Click swap to move output to input. Output becomes new input.

    Step 3: Apply second format (e.g., add comma suffix). Result: "text",

    Step 4: Continue swapping and formatting to build complex formats. Create nested wrappers or multi-layer formatting.

    Example: Plain text → [quote] → [bracket] → [comma] = ["text"], for JSON array creation.

    HTML & XML Formatting

    List Items: Prefix: "<li>", Suffix: "</li>" - Creates HTML list items. Wrap in <ul> or <ol> tags manually.

    Paragraphs: Prefix: "<p>", Suffix: "</p>" - Wraps each line in paragraph tags. Good for converting plain text to HTML.

    Divs with Classes: Prefix: "<div class='item'>", Suffix: "</div>" - Creates styled div containers.

    Table Rows: Prefix: "<tr><td>", Suffix: "</td></tr>" - Converts lines to table rows. Add more <td> tags for multiple columns.

    XML Tags: Add custom XML tags as prefix/suffix. Create structured XML data from plain text.
