About Text Repeater
Repeating text is simpler than it sounds — until you need the right separator, or to repeat hundreds of thousands of times without freezing your browser, or to avoid the character that breaks your destination system. Here's the tool and the footguns.
The common cases: generating sample data (500 rows of 'lorem' for a performance test), filling a field for validation testing (the max-length edge case), building seed content for a CMS migration, padding out a text file for a size-dependent test. Less common but legitimate: ASCII art, making placeholder decorative lines, filling spreadsheet cells for layout previews, and generating repetitive keyboard drills for typing practice.
The decision you care about is the separator. 'hello' repeated 5 times means five different things: `hellohellohellohellohello` (no separator), `hello hello hello hello hello` (space), `hello,hello,hello,hello,hello` (CSV), or `hello\nhello\nhello\nhello\nhello` (newline). This tool offers each — pick the one your destination expects. If you're pasting into a spreadsheet, use newline. Into a CSV column, use comma-no-space. Into a URL query parameter, use `,` or `;` (and remember to URL-encode after).
Large counts are where it gets interesting. Repeating a 10-character string 100,000 times produces 1MB of text. Most browsers handle that fine; pasting it into a <textarea> is where things slow down because the DOM has to render every character. If you need a million reps, generate into a file and download rather than copying.
What's the maximum count I can use?
The tool allows up to 100,000 repetitions to protect against accidental billion-character outputs. If you need more, chunk it: run 10 separate repeats and concatenate. Most real use-cases don't go above a few thousand.
Why is my output cut off?
If it looks cut off, it's usually the textarea scrolling rather than a truncation. Copy the content — the full repeated string is there. If you're pasting into another tool and THAT tool is cutting off, it likely has a field-length limit; check there.
Does it preserve special characters?
Yes — emoji, Unicode, tabs, and newlines inside the source text are preserved verbatim. If your input has a trailing newline, every repetition has that trailing newline.
Can I repeat with a random count each time?
Not from this tool — repetition here is deterministic. If you need 'between 3 and 7 times each', use a scripting language (Python/JS) with a random range. Randomness defeats most of the deterministic-testing reasons people use a repeater.
Will it handle multi-line source text?
Yes. If your source is `line1\nline2`, repeating 3x with newline-separator gives you six lines total. If that's not what you want, paste the source without its trailing newline or use a different separator.
