What it does
A small n8n workflow that counts how many items a node returns. It uses a Set node with the Execute Once option, and an expression that gets all incoming items and reads their length. It is a simple pattern for checking data volume during a flow.
Use cases
- 01Checking how many records a step returned
- 02Logging the item count before a bulk update
- 03Adding a count check while debugging a flow
