String Repeat
Repeat text any number of times with a custom separator. Fast, free, and 100% browser-based.
How does the string repeat tool work?
Enter your text, set the number of repetitions and an optional separator. The tool instantly repeats your text the specified number of times, joining each copy with the separator you chose.
What separators can I use?
You can use any character as a separator, including spaces, commas, semicolons, pipes, and special sequences like \n for newlines and \t for tabs.
What is the maximum number of repetitions?
The tool supports up to 10,000 repetitions. This limit ensures smooth browser performance even with long input text.
Is my text data sent to a server?
No. All text processing happens entirely in your browser. Your data never leaves your device, ensuring complete privacy.
What are common uses for repeating text?
Common uses include generating test data, creating placeholder content, building repeated HTML or CSS patterns, producing sample log entries, and duplicating text for design mockups.
Does the tool support Unicode and emoji?
Yes, the tool fully supports Unicode characters, accented letters, CJK characters, emoji, and all other character types.
Can I use this tool on my phone?
Yes, the tool is fully responsive and works on smartphones, tablets, and desktop browsers without any installation.
Is there an empty separator option?
Yes, leave the separator field empty to concatenate repeated text with no characters between copies.
How is this different from copy and paste?
This tool automates repetition with a single click, supports custom separators, and handles thousands of repetitions instantly - far more efficient than manual copy-paste.
Can I use the result as test data for programming?
Yes, developers commonly use this tool to generate repeated test strings, mock data patterns, SQL value lists, and CSV test content.
How to Use String Repeat
Repeat a piece of text as many times as you need, joined by any separator, entirely in your browser. Nothing you type is ever sent to a server.
- Type or paste the text you want to duplicate into the input area.
- Set Repeat count: to the number of copies you need, for example 10 or 100.
- Fill in Separator: with characters to place between copies, such as a newline, comma, or space; leave it empty to glue the copies together.
- Copy the repeated output below the input for use in your notes, code, or tests.
A newline as separator is an easy way to generate repeated mock rows for test data or quick filler content.
