Worked Examples

End-to-end walkthroughs that build a real flow from start to finish. Each one names the reader it serves, the nodes it uses, and the data it runs on, so you can pick the closest match to what you're building.

Examples

Example	For	Difficulty	Nodes	Data
Deduplicate and summarize sales data	Analysts new to Flowfile	Beginner	5	data/templates/supermarket_sales.csv
Build a sales dashboard from one cleaned table	Analysts wanting several views at once	Advanced	15	data/templates/supermarket_sales.csv
Export to Python	Python developers	Beginner	Any	Any flow

Connecting external data

Two more walkthroughs live under the Connect Your Data tab, since they start by wiring up a connection:

Example	For	Difficulty	Nodes	Data
Connect to a PostgreSQL database	Analysts with a database	Intermediate	Read from Database → Formula → Group by → Write to Database	A PostgreSQL table
Connect to AWS S3 and S3-compatible storage	Analysts with cloud data	Intermediate	Cloud Storage Reader / Writer	Files in S3 or MinIO

Every example here is validated by the test suite on each commit: the flow files live in data/templates/flows/ and the Python twins in docs/examples/, and both are executed end-to-end against the committed sample data.
