Text Repeater

What it does

Repeating a string N times is a five-second task in code (Python `"abc" * 5`, JavaScript `"abc".repeat(5)`) but a useful browser utility when you don't have a terminal handy or need to do it in the middle of writing prose. Common use cases: generating filler content for design mockups (40 lorem ipsum lines), creating indented templates (50 spaces for an ASCII banner), test data generation (1,000 row CSV with synthetic data), markup repetition (10 identical <li> elements for layout testing), URL or path repetition (parent- directory traversals: ../../../), and stress-testing input fields with long strings (10,000 character paste to see how your form handles it).

The tool takes any text string, a repeat count, and optional separator (newline by default — appears between repetitions, not before/after), then outputs the result. For repeat count 5 of “abc” with comma separator: “abc,abc,abc,abc,abc”. With newline separator (default): each repetition on its own line. Plus options for number suffixes (“item-1”, “item-2”, “item-3”, etc.) and surrounding wrappers (each repetition wrapped in <li>...</li>). Performance: handles repeat counts up to ~100,000 reliably; above that, browser memory limits kick in.

Quick code-equivalent reference for developers who want the “how would I do this in code” answer: Python `"text" * 5`, JavaScript `"text".repeat(5)`, Ruby `"text" * 5` or `"text".upcase * 5`, Bash `printf "text%.0s" {1..5}`, PowerShell `"text" * 5`, Go `strings.Repeat("text", 5)`, Java `"text".repeat(5)` (since Java 11), C# `string.Concat( Enumerable.Repeat("text", 5))`. For the JOIN case (with separator), most languages have idiomatic `join` / `String.Join` methods. The browser tool combines repeat + join in one place.

How to use it

1. Enter the text or character to repeat.
2. Set the repeat count (1-100,000 typical).
3. Optionally pick a separator (newline default; comma, space, or custom).
4. Optionally enable numbering (item-1, item-2, item-3, ...).
5. Click Repeat — copy the result.

When to use this tool

• Generating filler content for design mockups (placeholder lines).
• Test data generation (50 rows, 1000 rows of identical structure).
• ASCII banner padding (50 dashes, 80 spaces for column alignment).
• Stress-testing input fields with long strings.
• Quick repetition without opening a code editor or terminal.

When not to use it

• Generating realistic-looking placeholder text — use lorem ipsum or faker libraries that produce varied content, not just repeat.
• Production code generation — use proper templating (Handlebars, Jinja, Mustache) for repeating templated content.
• Very large outputs (over 1 million characters) — browser hits memory limits; use a script.
• Variable content (each repeat slightly different) — text-repeater produces identical copies; needs different tool.

Common use cases

• Onboarding a colleague who needs the same calculation/conversion
• Verifying a number or output before passing it on
• Quick use during a typical workday
• Pre-decision sanity-check on inputs and outputs
