What Repeat a Number can do:

The tool reads each line and repeats it the number of times you choose, using your custom separator. If you enable trimming, it cleans up the number first super useful when importing messy lists or manually typed input.

Each change you make reflects instantly in the output box. The live counter shows how many items were processed. And with the export button, you can drop your results into a spreadsheet or text editor in seconds.

You can use anything as a separator: spaces, commas, dashes, even emojis.

Example:

Input:

5
42

Settings: Times to repeat: 4, Separator: ” – “, Trim whitespace: ON

Output:

5 - 5 - 5 - 5
42 - 42 - 42 - 42
