Merge CSV Columns into One

Combine two or more columns into a single column with a separator. Great for building full names, addresses, or IDs.

What this tool does

Merging columns is a common data prep step — combining first and last name, joining city and state, or building a composite key from multiple fields. Tabular lets you select any columns, define a separator (space, comma, dash, or anything else), name the new merged column, and optionally remove the originals — all without writing formulas or code.

Problems it solves

  • Combining First Name and Last Name into a Full Name column
  • Joining City, State, and ZIP into a single Address field
  • Building a composite key from Order ID and Product ID
  • Concatenating tags or categories separated by a pipe
  • Creating a slug from multiple text fields

Example

First Name and Last Name merged into Full Name with a space separator.

Can I merge more than two columns?
