Best Feature for Importing and Combining Multiple CSVs into One Table | Clay

Best Feature for Importing and Combining Multiple CSVs into One Table

·Jan 13, 2026 08:28 PM·

My goal is to import 5-10 CSVs as tables which are company sources. I then want to combine these into one table, while mapping the columns to existing columns in my new table to then run enrichments on that data. What feature best serves this use case?

For your use case, you'll want to use CSV import combined with Send table data (also called "Write to Other Table").
Here's the workflow:
1.
Import each CSV separately - Use Actions → Import → "Import from CSV" to bring each company source into its own table [1]
2.
Create your master table - Set up one main table with the column structure you want for enrichments [2]
3.
Use "Send table data" to combine them - This feature lets you map columns from each source table to your master table. You can map data from source columns to existing columns or create new ones [3]
The Send table data feature creates a source column in your destination table, then you click into cells, hover over fields, and use "Add to column" to map them to your existing columns
You can also set up auto-update so new rows get enriched automatically [4]
Before diving in, try asking Sculptor (our AI tool in the top-right corner) to help set up this workflow - it's free and can guide you through building the table structure and automations quickly.
