When to use
- Vertical (rows): Combine two CSV files that have the same columns (e.g. January data + February data).
- Horizontal (columns): Attach a new set of columns to an existing DataFrame when rows are already aligned.
Data Wrangling
Concatenate DataFrames component
Stack two DataFrames vertically to add more rows or horizontally to add more columns, with control over index alignment and join behavior.
The Concatenate component appends one DataFrame to another along a chosen axis — useful for combining datasets that share the same schema, or for adding new columns.
