Load the fictional example in a cleared form. Check the options, run the tool if needed, and compare the result below.
Repeat the exact text 1 to 1,000 times, inserting the selected separator only between copies. A live estimate shows the output length in UTF-16 code units, including separators. Enter text and a whole number from 1 to 1,000. Choose a new line, a space, no separator, or custom text. The live estimate shows the output size; separators appear only between copies. Output is capped at 1,000,000 UTF-16 code units to avoid oversized results. With one copy, no separator is needed; blank input is not accepted.

How to use it
Enter text and a whole number from 1 to 1,000. Choose a new line, a space, no separator, or custom text. The live estimate shows the output size; separators appear only between copies.
Limits
Output is capped at 1,000,000 UTF-16 code units to avoid oversized results. With one copy, no separator is needed; blank input is not accepted.
Frequently asked questions
Is a separator added after the last copy?
No. Separators appear only between copies. If you choose a custom separator, it must contain text when you make more than one copy; choose None for adjacent copies.
Why can the size estimate differ from the number of visible characters?
The limit and estimate count UTF-16 code units, the units used by JavaScript String.length. One emoji such as 🚀 can count as two units. The maximum output is 1,000,000 units, including separators.
How many copies can I make?
Choose a whole number from 1 to 1,000. One copy does not need a separator.
