What is a List Merger?
A list merger is a tool that combines two separate lists into one. You can choose different merge modes like appending one list to another, interleaving items from both lists, or zipping them together.
The tool supports multiple input and output separators, allowing you to work with comma-separated values, line-by-line lists, or other formats. You can also remove duplicates, trim whitespace, and filter out empty items.
All processing happens locally in your browser, ensuring your data remains private and secure.
Merge Modes
Append Mode
Simply combines List 1 followed by List 2. Perfect for concatenating two lists into one larger list.
Interleave Mode
Alternates items from each list: first item from List 1, first item from List 2, second item from List 1, and so on.
Zip Mode
Combines corresponding items into pairs. The first item from List 1 is joined with the first item from List 2.
Alternate Lines
Similar to interleave, but treats each input as complete lines rather than individual items.
Frequently Asked Questions
How do I remove duplicate items after merging?
Check the "Remove duplicates" option before merging. The tool will automatically remove any duplicate items from the merged result.
Can I use different separators for input and output?
Yes! You can choose different separators for input (how items are separated in your lists) and output (how items should be separated in the result).
What happens if the lists have different lengths?
In Append and Interleave modes, all items from both lists are included. In Zip mode, the result is limited to the length of the shorter list.
Can I swap the two lists?
Yes! Click the "Swap Lists" button to exchange the contents of List 1 and List 2.
