What is List Splitter?
List Splitter takes a line-separated list and breaks it into groups — fixed size chunks, a target number of buckets, or sections already separated by blank lines.
Part of the List Ops cluster. Clean duplicates with Remove Duplicates from List before you split.
Modes
Every N lines
Groups of size N. Last group may be shorter. Default on Split List into Chunks is N=10.
Into K groups
Distribute items into K buckets as evenly as possible — ideal for A/B splits.
By blank line
Treat blank lines as section breaks. Keeps multi-line sections intact.
How to use it
Paste your list
One item per line into the input.
Pick a mode
Chunk by N, into K groups, or blank-line sections.
Set N or K
Adjust the number; optionally label groups and drop blanks.
Copy groups
Copy all, or copy one group at a time.
Tips
For email A/B tests: dedupe first, then use Into K groups with K=2 so both buckets are as equal as possible.
Label groups when you will paste into a doc and need headings. Turn labels off when feeding a script that expects raw lines only.
