Repeat any text a set number of times with a separator

String Repeater takes a piece of text and repeats it as many times as you specify, optionally joining the copies with a separator of your choice. Enter the string, set the count, pick a separator — a comma, space, new line or custom text — and the multiplied output appears instantly. It replaces the tedium of copying and pasting the same snippet dozens of times and gives you precise, repeatable output every single time.

The tool is a quiet workhorse for developers and testers. Need a thousand rows of sample data, a long string to stress-test an input field, or a block of repeated markup for a mockup? Repeating text handles all of it in one click. Writers and designers use it too, for building separator lines, filler content, or repeated placeholders, while anyone dealing with spreadsheets can generate comma- or newline-separated values ready to paste straight into a column.

Because it runs entirely in your browser, repetition is instant and completely private — your input and output never touch a server. After generating, the tool reports the total character and line count so you know exactly how large the result is, and you can copy it to the clipboard or download it as a text file. There is no signup, no install, and no limit beyond what keeps your browser responsive.

Why use String Repeater?

Custom separators

Join repetitions with commas, spaces, new lines or any custom text to fit your format.

Precise repeat counts

Specify exactly how many copies you need for reliable, repeatable output every time.

Output statistics

See the total character and line count of the result so you always know its size.

Fast and private

Runs in your browser with no uploads, so even proprietary text stays on your device.

Common use cases

Generate test data

Create long lists or repeated rows to populate databases and test application behavior.

Stress-test inputs

Frequently asked questions

What can I use a string repeater for?

Repeating text is handy for generating test data, creating filler content, building repetitive markup, producing separator lines, and stress-testing input fields with long strings. Developers, QA testers, writers and designers all use it to save the tedium of copying and pasting the same snippet over and over.

Can I add a separator between repetitions?

Yes. You can insert any separator between each copy, including commas, spaces, new lines, or custom text. New-line separation is especially useful for building lists, while comma separation quickly produces CSV-style values. The separator is not added after the final repetition.

Is there a maximum number of repetitions?

The tool allows large counts, but because everything runs in your browser, extremely high numbers combined with long text can produce huge output that slows your device. A sensible upper bound keeps the interface responsive; for most testing and formatting needs a few hundred to a few thousand repetitions is plenty.

Does it count the output for me?

Yes. After generating, the tool shows the total character and line count of the result so you know exactly how much text was produced. You can then copy it to the clipboard or download it as a text file with a single click.

Will my input be sent anywhere?

No. Repetition is performed entirely in your browser using JavaScript. Your input and the generated output stay on your device and are never uploaded, logged or stored, so the tool is safe to use with private or proprietary text.

Your privacy matters

String Repeater runs entirely in your web browser. Your files, text, and data are never uploaded to any server, never stored, and never seen by us or any third party. This client-side architecture means you can safely process confidential business documents, personal records, and proprietary data without privacy concerns.
