Duplicate Lines Tool
Repeat each card line a set number of times — for example, enter 2 and every line is copied twice.
How to use
Steps
- Enter how many copies of each line you want in "Repeats per line" (an integer, at least 1).
- Paste your cards into "Original text", one per line.
- Click "Duplicate". The output repeats each line in order.
- Copy the result or export it as TXT.
FAQ
Q: Can I enter a decimal for the repeat count?
A: Only integers are accepted. A value below 1 or non-numeric input triggers an error and nothing runs.
Q: What is the order after repeating?
A: Each line is copied in its original order. For example, two lines A and B each repeated twice give A, A, B, B.
Q: Does repeating create extra blank lines?
A: No. The number of output lines equals the number of input lines times the repeat count, with no extra blanks.
