Frequently Asked Questions
What does interleaving do?
It weaves two lists together by taking one item from each in turn, so list A and list B alternate down the result.
What if the lists are different lengths?
The items pair up until the shorter list runs out, then the remaining items from the longer list are added at the end.
How is this different from zipping?
Interleaving puts each item on its own line, alternating. Zipping joins the matching items from each list onto the same line with a separator.
Can I interleave more than two lists?
This tool takes two lists. To combine more, interleave the first two and then interleave the result with the next list.
Are my lists uploaded?
No. The combining runs in your browser and your lists never leave the tab.
