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

  1. Enter how many copies of each line you want in "Repeats per line" (an integer, at least 1).
  2. Paste your cards into "Original text", one per line.
  3. Click "Duplicate". The output repeats each line in order.
  4. 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.
