How to Use
- Enter the string or multiline block to repeat.
- Set repeat count and choose a separator — newline, comma, space, tab, custom, or random.
- Enable options such as per-line repeat, numbering, prefix, suffix, or reverse output order.
- Review live stats for output size, lines, and total generated items.
- Copy output, copy stats, or download. Chain with Number Lines or Sort Lines from Formatting Tools.
Repeat Modes Explained
Each mode builds output differently — pick the pattern that matches your mock data or list generation task.
Repeat each line
Repeats every input line separately — ideal for multiline lists.
In: A / B
Out: A×n then B×n
Numbered repetitions
Adds 1., 2., 3. before each repeated item.
In: user
Out: 1. user / 2. user / 3. user
Prefix + repeat
Prepends a fixed prefix to every copy.
In: John
Out: ID_John / ID_John / ID_John
Suffix + repeat
Appends a fixed suffix to every copy.
In: Item
Out: Item_2026 / Item_2026
Reverse order
Flips the sequence of generated items after repeating.
In: A / B / C
Out: C / B / A
Custom separator
Join copies with any delimiter you define.
In: apple
Out: apple, apple, apple
No separator
Concatenates copies directly with no delimiter.
In: Hi
Out: HiHiHi

Separator Comparison
| Separator | Delimiter | Example | Best for |
|---|---|---|---|
| New line | \n | HelloHello | CSV rows, lists, line-by-line output |
| Space | | Hello Hello | Inline text, tags, single-line output |
| Comma | , | Hello, Hello | CSV inline, comma-separated values |
| Pipe | | | Hello | Hello | Pipe-delimited exports |
| Dash | - | Hello - Hello | Readable inline separators |
| Tab | TAB | Hello[TAB]Hello | Spreadsheet paste, TSV columns |
| Custom | User-defined | Hello::Hello | JSON fragments, SQL, special formats |
Generation Patterns
Markdown lists
Input - item, newline separator, repeat 3×.
- item - item - item
HTML lists
Repeat <li>value</li> with newline separator.
<li>value</li> <li>value</li>
CSV rows
One value per repetition — paste into spreadsheet columns.
apple apple apple
JSON arrays
Repeat quoted values with comma separator.
"id", "id", "id"
SQL value lists
Repeat ('value') with comma for IN clauses.
('value'), ('value'), ('value')
Repeat vs Copy-Paste
| Factor | Repeat Text tool | Manual copy-paste |
|---|---|---|
| Speed | Instant at any count up to 10,000 | Slow — multiple paste cycles |
| Consistency | Identical copies every time | Easy to miss or duplicate rows |
| Error reduction | Change count once — no manual counting | Off-by-one mistakes common |
| Large outputs | Built for hundreds or thousands of rows | Impractical at scale |
| Live updates | Separator, prefix, and count update output instantly | Must redo entire paste workflow |

Frequently Asked Questions
How many repetitions are supported?
Up to 10,000 repetitions per run. Very large counts may take longer depending on your device — generate in batches if needed.
Can I repeat multiline text?
Yes. The entire multiline block repeats as one unit by default. Enable preserve original formatting to keep internal line breaks.
Can I repeat each line separately?
Yes. Enable repeat each line separately to duplicate every input row on its own before moving to the next line.
Can I add numbering?
Yes. Enable number repeated items to prefix output with 1., 2., 3., and so on.
Can I add prefixes?
Yes. Enter a prefix value to prepend every repeated copy — for example ID_ before each username.
Can I add suffixes?
Yes. Enter a suffix value to append every repeated copy — for example _2026 after each item.
Can separators be empty?
Yes. Choose no separator to concatenate copies directly with no delimiter between them.
Will spaces be preserved?
Yes. Spaces in your input repeat exactly as entered unless you enable trim whitespace before repeating.
Can I generate CSV rows?
Yes. Paste one value per line, set repeat count, and use newline separator to build duplicate CSV-style rows.
Can I reverse the output order?
Yes. Enable reverse output order to flip the sequence of generated items after repeating.
Does this work with Unicode?
Yes. Unicode letters, numbers, and symbols are preserved in repeated output.
Is my text uploaded?
No. Generation runs entirely in your browser. Your text is not uploaded to a server.
Can I download the result?
Yes. Use Download .txt to save the output, or Copy Output to paste it elsewhere.
