Repeat Text - Duplicate Text N Times

Example

Base text

Hello

Repeated 3× (newline)

Hello
Hello
Hello

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 entire text

Duplicates the full input block including internal line breaks.

In: Hello

Out: Hello / Hello / Hello
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`	`Hello` `Hello`	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

Typical Output Sizes

Small (10)

Quick lists, markdown bullets, sample API payloads.

~50 chars for Hello
Medium (100)

CSV test rows, form stress tests, placeholder columns.

~500 chars for Hello
Large (1,000)

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.
