Repeat Text

What Repeat Text helps you do

Repeat a string a chosen number of times with an optional separator between copies. Useful for generating padding, test data, dividers or long strings without copy-pasting by hand. The separator is inserted between copies only, so the last copy does not end with it.

Repetition is computed locally in your browser and nothing is uploaded.

How it works

Line tools split the pasted text into lines, apply one operation to the list, and rejoin it with a newline. A blank line is still a line, so it participates in sorting, numbering and shuffling unless you remove it first. The transformation runs in the browser and keeps the existing line order except where the tool's purpose is to change it. Nothing is uploaded, and the output replaces the preview rather than the source. If the input ends with a newline, the final empty line can affect a count or a shuffle; trim the input first when that matters.

How to use Repeat Text

1. Enter the text to repeat and the number of copies.
2. Add a separator such as a comma or newline if you need one between copies.
3. Generate and check the first and last copies.
4. Copy the repeated output.

When to use it

• Create a line of repeated characters as a visual divider.
• Fill test fixtures with a known repeated value.
• Pad a string to a target length for a fixed-width field.
• Generate repeated placeholders for a template.
• Build a comma-separated run of identical values.
• Create a long sample string for a layout test.

When not to use it

• Do not use it for very large outputs that exceed the character cap.
• Do not use it to generate random data; the result is deterministic.
• Do not expect the separator to appear after the final copy.

Example

Repeating ab three times with a dash separator gives ab-ab-ab. With a newline separator, each copy appears on its own line. A count of zero returns an empty string, and a very high count is capped so the browser stays responsive.

What you can do with Repeat Text

• Repeat a string from 0 to 10,000 times.
• Insert a custom separator between copies.
• Use a newline, comma, dash or no separator.
• Cap very large output to keep the page responsive.
• Copy the repeated result.
• Run the repetition locally with no upload.

Example: check the line structure first

Paste a small sample and note how many lines it has, including blank lines and a possible trailing newline. The count explains most surprises after sorting, numbering or filtering.

Apply the operation and compare the first and last lines with the source. If the structure is right, run the full text; if not, remove the blank lines or trim the input first.

Copy or download the result and keep the original until the destination accepts it. Line tools are one-way, so the source is the only undo.

For a list pasted from a spreadsheet, check for hidden carriage returns or wrapping quotes before transforming it. A stray quote can sort differently or survive a filter that looks correct at a glance.

When the result feeds another tool, run a second pass only after confirming the first. Chaining a sort and a deduplication is safe, but chaining two numbering steps produces duplicated prefixes.

If the output is going into a version-controlled file, check the diff before committing. A blank-line or line-ending change can look like a content change in review even when the words are unchanged.

What to know before you start

• Large repeat counts produce very long output that can slow the browser.
• The separator is inserted between copies only, not after the final one.
• Output is capped around 500,000 characters.
• The result is deterministic, not randomized.

Common mistakes

• Expecting a trailing separator after the last copy.
• Repeating a long string thousands of times and hitting the output cap.
• Forgetting that the separator counts toward the output size.
• Using a count of zero and expecting one copy.

Troubleshooting

If the output is shorter than requested, the character cap limited the count.

If there is no separator, the field may be empty or an escaped sequence was not interpreted.

If the result is empty, the count is zero or the source string is empty.

If the page slows down, reduce the repeat count.

• A newline is a single line separator in Unix text; Windows files may use CRLF.
• Modern JavaScript sorts are stable, so equal lines keep their relative order.
• Blank lines are entries, not separators, in these transformations.
• A trailing newline is a text convention, not content; remove it before counting lines.
