Understanding text repeating
One string, copied N times.
The smallest text utility — useful surprisingly often.
What it does and why.
Take a string, multiply it. The separator picks how the repetitions are joined: newline for a column of values (filling test data), comma for SQL IN (…) clauses, space for stress-testing line breaks, nothing for raw multiplication. The output is always the input N times exactly — useful for fixtures, load testing, layout testing, generating mock CSV columns.
Where it shows up unexpectedly.
Generating a list of unit-test inputs of a specific length. Filling a textarea to test scrolling. Building long URLs to verify a header limit. Making fake spreadsheet rows to demo a feature. None of these are common but every one happens often enough that having a lever for "make me fifty of these" feels right.
Practical limits.
The browser handles roughly a million characters before textareas start to feel sluggish. If you need genuinely enormous repeated payloads — gigabytes, for a load test — generate them server-side; this is a tool for everyday-scale repetition, not for stress-testing infrastructure.
