What is a Text Duplicator?
A text duplicator takes a block of text and repeats it a specified number of times, with optional separators between repetitions. It's a simple but surprisingly useful tool for developers, testers, and content creators.
Common Use Cases
- Testing UI layouts: Fill a text area with repeated dummy content to test overflow, wrapping, or scrolling behavior.
- Load testing data: Generate repetitive test records (usernames, addresses, items) for bulk import testing.
- Form validation testing: Test character limits by duplicating text until you hit the limit.
- Repetitive content generation: Create legally repetitive disclaimers, terms, or boilerplate text.
- Music lyrics or chants: Quickly repeat a chorus or phrase many times for practice sheets.
How to Duplicate Text Online
1Open the Text Duplicator tool.
2Type or paste the text you want to repeat.
3Enter the number of repetitions (e.g., 5, 10, 100).
4Choose a separator: none, newline, comma, pipe, or custom.
5Click Duplicate and copy the output.
💡 Dev Tip: Use the duplicator to quickly generate placeholder list items, table rows, or div blocks for HTML/CSS layout prototyping. Just duplicate a single element and paste into your editor.
Separator Options
- None: All repetitions joined together without any space or break.
- Newline: Each repetition on its own line — great for lists.
- Comma: Useful for CSV data or function arguments.
- Custom: Use any separator, such as a pipe
|, dash—, or space.
FAQ
Is there a maximum number of duplications?
The tool runs in your browser, so very high repetition counts (10,000+) with long text may slow down or freeze the tab. For most practical uses (1–1,000 repetitions), it works instantly.
