About the List Merger
The List Merger lets you combine two separate lists into one. Whether you're dealing with structured data, names, or random entries, this tool simplifies the process of putting two lists together.
Appending one list after another by hand means carefully copying and pasting without dropping or duplicating a line — easy to get wrong with anything beyond a few entries. This tool combines both lists in one click, keeping every item exactly as it was, in order, ready to copy out or feed into another tool (like a duplicate remover, if you need the result deduplicated).
How to Use This Tool
Paste both lists
Enter the first list and the second list, one item per line.
Click "Merge Lists"
The second list is instantly appended after the first.
Copy the result
Use the "Copy" button to save the combined list.
Common Use Cases

Building a Master List: Append additional entries onto an existing list to build a comprehensive master version.
Preparing Data for Deduplication: Merge two lists first, then run the result through a duplicate remover to clean it up.
