How to Generate Line Combinations Online

TL;DR: Need every possible combination from multiple lists? The Line Combination Generator tool creates all combinations from two or more lists, with delimiters between items, prefix and suffix wrapping, shuffle, and duplicate removal. Everything runs in your browser.

You have a list of first names and a list of last names and need every possible full name. Or a set of product colors, sizes, and materials that must be combined into every variant. Writing nested loops or doing it by hand wastes time and invites mistakes.

TextModifier's Line Combination Generator tool takes multiple lists and produces every combination instantly, with full control over formatting and filtering.

How It Works

1. Enter items in List 1, one per line
2. Add one or more additional lists with the Add List button
3. Optionally set a delimiter between each pair of lists
4. Configure prefix, suffix, and join separator as needed
5. Click Generate

The tool multiplies every item in List 1 by every item in List 2, and so on for each additional list. The combination count updates in real time before you generate, so you know exactly how many results to expect.

Adding Multiple Lists

Click Add List to create as many lists as you need. Each list gets its own text area where you enter items one per line. Remove a list by clicking the X button next to its header.

You can reorder lists by dragging and dropping them. Each text area also accepts drag-and-drop file uploads. Drop a .txt file directly onto a list to load its contents.

Delimiters Between Lists

A delimiter field appears between each pair of adjacent lists. This controls the text inserted between items from those two lists in each combination.

For example, with List 1 containing first names and List 2 containing last names, setting the delimiter to a space produces John Smith. Setting it to , produces John, Smith. Leave it empty to concatenate items directly.

The delimiter supports escape sequences. Use \n for a line break and \t for a tab character.

Wrapping Combinations with Prefix and Suffix

The Prefix field adds text to the beginning of each combination. The Suffix field adds text to the end. Together, they wrap every result in a consistent format.

For example, with prefix <option> and suffix </option>, a combination of "Red" and "Large" with a space delimiter produces:

<option>Red Large</option>

Built-In Presets

Use the Presets dropdown to fill both prefix and suffix fields with a single click:

• Double Quotes: "..."
• Single Quotes: '...'
• Parentheses: (...)
• Square Brackets: [...]
• Curly Braces: {...}
• HTML <li>: <li>...</li>
• HTML <p>: <p>...</p>
• SQL Values: ('...') with trailing comma
• Comma Suffix: appends ,
• Tab Prefix: prepends a tab character

Controlling the Join Separator

The Join separator field defines the text placed between each combination in the output. The default is \n (newline), which puts each combination on its own line. Change it to , for a comma-separated list, or \n\n for double-spaced output.

Filtering and Cleaning Options

Four checkboxes refine the output before it's displayed:

Skip Empty Lines

Enable Skip empty lines to ignore blank lines in each list when generating combinations. Without this, an empty line counts as an item and produces combinations with missing parts.

Trim Items

Enable Trim items to remove leading and trailing spaces from each item before combining. This cleans up inconsistent spacing from copy-pasted data.

Shuffle Output

Enable Shuffle output to randomize the order of the generated combinations. The default order is systematic: List 1 item 1 paired with every List 2 item, then List 1 item 2, and so on. Shuffling is useful for randomized test data or avoiding predictable patterns.

Remove Duplicates

Enable Remove duplicates to eliminate identical combinations from the output. This matters when lists contain repeated items that would produce the same result.

Real-World Use Cases

Generating Product Variants

Combine lists of colors, sizes, and styles to produce every SKU or product variant. Set the delimiter to - to get results like Red - Large - Cotton.

Creating Test Data

Build combinations of usernames, domains, and TLDs to generate test email addresses. Shuffle the output for randomized test datasets.

Building URL Paths

Combine base paths, categories, and slugs to generate all possible URL structures for a sitemap or redirect map.

Producing Keyword Combinations

Combine modifier words, core keywords, and location terms to expand a seed keyword list for SEO or PPC campaigns.

Generating Name Lists

Combine first names and last names to create a full roster. Use prefix and suffix to wrap each result in the format your destination system expects.

Privacy and Speed
