Text Repeater
This text repeater duplicates whatever you type a set number of times, joined by any separator you choose — a newline, a comma, a tab, or literal text of your own. Numbering each copy turns it into a quick generator for test data, placeholder lists, numbered fixtures and repeated markup. It is also the fastest way to produce a long string for testing how a field, a database column or a layout handles length. The count is capped at ten thousand copies, which is enough for any realistic test while keeping the page responsive.
How it works
Repeats the text a set number of times, joined by whatever separator you choose. Use \n for a newline, \t for a tab, or type any literal text such as ", ".
Numbering each copy makes this useful for generating test data, placeholder lists or numbered fixtures.

Separators
The separator accepts escape sequences as well as literal text. \n puts each copy on its own line,
\t separates them with tabs for pasting into a spreadsheet, and anything else you type is used
exactly as written — including nothing at all, which runs the copies straight together.
Testing length limits
A common use is finding out what a system does with a value longer than it expects. Repeating a short string until you have exactly 256, 1000 or 65,536 characters gives you a precise test case, and the character count under the output tells you when you have hit the number you wanted.
Numbered output
Numbering makes each copy distinguishable, which matters when you are pasting rows into a form or a database and need to tell afterwards which one is which.
Frequently asked questions
How do I repeat text?
Type or paste the text, set how many copies you want, and choose the separator. The result appears immediately.
How do I separate copies with a newline?
Type \n in the separator field. \t gives a tab, and any literal text such as ", " works as written.
Can I number the copies?
Yes. Tick "Number each copy" and every repetition is prefixed with its position, starting at 1.
What is the maximum?
Ten thousand copies. That is enough for any realistic test while keeping the page responsive.
What is this useful for?
Generating test data, filling a form field to check its length limit, producing placeholder lists, and testing how a layout behaves with long content.
Is my text sent anywhere?
No. Everything happens in your browser.
