Clay doesn't have a direct row merging feature. You have two options:
Option 1: Use Write to Table
Transfer data between tables using our "write to table" integration, then use Merge Columns to combine data from different columns.
Option 2: Manual Process
1.
Click Add Column → Merge columns
2.
Input formula to combine data from multiple columns
3.
Use deduplication separately to remove duplicate rows [1]
The dedupe feature only removes duplicate rows based on exact matches - it doesn't merge their information.

I have 8 lists of prospects. Each list represents a feature a prospect is interested in. A prospect could be on 3 or 4 lists at a time. I want to be able to merge those so 1 prospects appears once with his 3 or 4 interests in one box. How could I do this?

Use our "write to table" integration to consolidate your 8 prospect lists:
1.
Create a destination table for your merged prospects [1]
2.
Use write to table to transfer data from each of your 8 feature lists to this destination table
3.
Add a merge columns to combine the interests: • Click Add Column → Merge columns • Input formula to combine the feature columns (e.g., /Feature1/Feature2/Feature3/Feature4) [2]
4.
Enable auto-deduplication on the prospect identifier (like email or name) to ensure each prospect appears only once
This will give you one row per prospect with all their interests combined in a single field.

But how will I merge the interests together from 2 different rows and not 2 different columns?

Clay's merge columns feature only combines data from different columns, not different rows. [1]
For your use case with 8 prospect lists, use write to table with auto-deduplication:
1.
Set up auto-dedupe on your prospect identifier (email/name) in the destination table [2]
2.
When write to table transfers data from each list, auto-dedupe will keep only one row per prospect
3.
Each transfer will update the existing row rather than create duplicates
This automatically merges prospect information from multiple rows into single rows.
