Text Repeater & Multiplier

Sometimes the job is simply producing the same string many times over: seeding a test fixture, generating a CSS stress-test, filling a spreadsheet column, or building a rhythm in a creative piece. Typing it by hand is error-prone past about the fifth copy; most word processors offer no repeat primitive at all. Text Repeater takes a string and a count and handles every mechanical detail in a single step.

Six separator presets cover the most common layouts without requiring any manual stitching. New Line stacks each copy on its own row, Space runs them into a single line, Comma and Pipe produce formats that paste directly into spreadsheets or command-line argument lists, None concatenates copies with nothing in between, and Custom lets you type any arbitrary string as the glue.

Worked Example: Five Copies on Separate Lines

Click Load Sample to fill the input with Launch sequence confirmed. and set the count to 5 with the New Line separator active. The output textarea shows five lines, each containing the phrase exactly as typed. The stats bar reports 5 copies, 145 characters, and 5 lines.

• Switch the separator to Pipe and the output collapses to a single line: Launch sequence confirmed. | Launch sequence confirmed. | …— useful for building a lookup table or a shell one-liner.
• Switch to None to concatenate all copies with no gap. A five-copy run of na produces nanananana — handy for padding tests or synthetic data.
• The Trim whitespace checkbox strips any leading or trailing spaces from the input before repeating. Most visitors miss it on the first visit, yet it is the one control that prevents an invisible trailing space from corrupting a Comma or Pipe output.

What Each Separator Produces

• None joins copies with an empty string. Input length × count = output length exactly.
• New Line inserts a single \n between each copy. The line count equals the repeat count.
• Space inserts one space character. Output is a single line of space-separated copies.
• Comma inserts , (comma + space). Paste the result straight into a CSV cell or a JavaScript array literal.
• Pipe inserts | (space + pipe + space). Matches the column separator used by Markdown tables and many shell tools.
• Custom reveals a text field. Any string is valid, including multi-character sequences such as → or \t typed as two characters.

Size and Performance: Ceilings the Tool Enforces

• The repeat count is capped at 500. Entering 501 shows the message Maximum repeat count is 500 — enter a number between 1 and 500.
• Output longer than 50,000 characters is blocked before it is written to the DOM, so the browser tab stays responsive even when input is long and the count is near the ceiling.
• A count of 0 or a blank count field shows Repeat count must be a whole number of at least 1. No output is produced until the field holds a valid positive integer.
• All processing is local. The text never leaves the browser tab.
