How it works: Join columns
Combine spreadsheet columns into a single value using spaces, commas, pipes or another separator. Each source row remains a separate output row.

Common uses
- Join first and last names
- Build labels from several fields
- Create paths, tags or display strings
Formats and limits
- Input columns are parsed using the selected separator, including quoted fields. The output joins fields within each record.
- Joining loses column boundaries unless the chosen separator is unambiguous. This is not a reversible CSV conversion.
