Repeat any text a set number of times with your choice of separator — for testing, data generation, and more.
Editing and transforming text manually is tedious and error-prone. Text Repeater automates the process so you can repeat any text a set number of times with your choice of separator — for testing, data generation, and more in one click. It works with any length of text, from a single sentence to thousands of lines, and runs entirely in your browser for complete privacy.
Text repetition has many practical applications: Software testing — generate large amounts of repeated placeholder data to test how applications handle long strings, database fields, or UI overflow. Data generation — create CSV rows, JSON arrays, or SQL INSERT statements by repeating a template. Design/layout — fill mockup designs with repeated "Lorem ipsum" style content. Music/poetry — create refrains, choruses, or anaphora patterns. Padding — create fixed-width strings or fill buffers for encoding tests.
This tool supports up to 10,000 repetitions. Very large outputs (millions of characters) can slow down your browser since the text is processed entirely in JavaScript in your browser. For output larger than ~1 million characters, we show only a preview in the text area but copy the full string when you click "Copy Output." If you need to generate very large datasets regularly, consider scripting the repetition in Python or using a terminal command like yes "text" | head -n 1000.
The tool offers six preset separators: None (all repetitions joined together), Newline (each repetition on its own line), Comma (comma-space separated, great for CSV), Space (space-separated), Pipe (pipe-separated, useful for shell scripts or Markdown tables), and Tab (tab-separated for spreadsheet imports). The Custom option lets you enter any separator string, including multi-character separators like " | " or " → ".
