Flexible generation
Build repeated content without manual duplication
Use plain repetition for quick lists, line mode for multiple source values, or template variables to generate indexed labels and test data.
- Add source textUse one block or multiple non-empty lines.
- Configure outputSet count, numbering, separators, prefix, and suffix.
- Generate safelyReview the size estimate, then copy or download.
Common uses
Delimiter-separated data
Join repeated values with commas, tabs, spaces, line breaks, or escape-aware custom text.
Template generation
Combine {text}, {n}, {n0}, and {total} in source, prefix, or suffix.
Per-line repetition
Repeat every non-empty input line while maintaining one continuous output sequence.
Frequently asked questions
How do escape sequences work in a custom separator?
\n becomes a newline, \t becomes a tab, \r becomes a carriage return, and \\ becomes one backslash.
Why is output limited to 5 MB?
The limit protects mobile devices and browser tabs from accidental memory pressure caused by very large repetition counts.
Does the repeat count apply to every line?
Yes when per-line mode is enabled. Three source lines repeated five times produce fifteen output items.
