How to use Repeat a String
- 1. Paste the string to repeat. Enter the text you want duplicated into the input pane, whether it's a single character, a word, or a longer phrase.
- 2. Set how many times. Enter a number into Times to control how many copies appear in the result, from a couple of repeats to a large batch.
- 3. Choose a separator between copies. Pick Nothing, Newline or Space in Separate copies with, depending on whether the repeated copies should run together, stack on separate lines, or sit apart with spaces.
- 4. Copy the repeated result. Copy the duplicated text from the output pane into test data, a filler block, or wherever repetition is needed.
When to use Repeat a String
Repeat a String duplicates a piece of text a chosen number of times, joined however you like, with nothing between copies, a newline, or a space. It's for building filler content, test data and repeated patterns quickly, without a loop or a spreadsheet formula.
- Building filler test data quickly. You need a placeholder value repeated many times to fill a table or list for a UI mockup. Setting Times to 20 with a newline separator produces a ready-made column.
- Creating a visual separator line. You want a horizontal rule made of dashes or equals signs for a plain-text document. Repeating the character with no separator gives you a solid line of any length.
- Generating a stress-test payload. A load test needs a large repeated string to simulate a bulky request body. Repeating a short pattern many times with no separator quickly builds that payload.
- Padding out a demo transcript. You're preparing sample content for a chat UI demo and want a repeated phrase across several lines to simulate multiple messages, using the newline separator to stack them.

About the Repeat a String tool
