Merge & Interlace Text Lists
Combine two or more lists of text into a single cohesive list. Perfect for merging names and emails, interlacing alternating lines, or appending prefixes side-by-side using local browser processing.
Advanced List Manipulation
Data formatting often requires combining disparate lists. Whether you are interlacing a list of first names with last names, or merging URLs with anchor texts, doing this manually is impossible at scale. Our text list merger allows you to interlace lines sequentially or append them side-by-side with a custom delimiter.
Why Use Our Merge Text Lists?
- Custom Delimiters: Separate merged lines with commas, pipes, tabs, or spaces.
- Alternating Merge: Zip two lists together like a zipper (Line 1A, Line 1B, Line 2A...).
- Side-by-Side Append: Join line 1 of List A directly to line 1 of List B.
- Offline Capable: All text manipulation happens instantly in JavaScript.
How to Use the Merge Text Lists
Paste your first list into the primary text area.
Paste your second list into the secondary text area.
Choose your merge style (Interlace or Side-by-Side).
Click 'Merge' to generate your combined output.
