Merge (data)
Combining two or more data sets into a single output. In automation: merging customer data from CRM with order history from Shopify to create a unified customer profile that feeds into a personalised email.
Expert insight
Merging data from two sources with overlapping but not identical schemas requires an explicit decision about which source wins when both have a value for the same field, a merge without this decision made deliberately falls back to whatever the tool's default behavior happens to be, which is rarely documented and rarely what anyone intended.
In a real workflow
Results from two parallel branches are merged into one record before saving.
Common mistakes
- Merging by position instead of by key.
- Duplicate records after merging.
Complexity level
Requires some familiarity with automation concepts.
