About the Text Merge Tool
Whether you need to combine two massive columns of data, link first names with last names, or interlace two separate logs, the OnlinePaste.com Text Merge tool handles complex list combinations instantly without ever needing to open spreadsheet software.
Multiple Merge Modes
- Line-by-Line Join: Concatenates lines side-by-side. (e.g., Line 1 from A + Separator + Line 1 from B).
- Alternate Lines (Zipper): Shuffles lists together like a zipper. (Line 1 from A, Line 1 from B, Line 2 from A...).
- Append: Simply stacks List B directly underneath List A.
