# Merge

Merge datasets in a structured, repeatable way on the Cascade canvas. Connect the [Append](/cascade/tools/combine/append.md) tool to multiple upstream tables to merge their rows. Use the [Join](/cascade/tools/combine/join.md) tool to merge two datasets into a single table, based on a shared column.
