Business problem

Recurring exclusion files needed stable generation and change-aware processing. Without automation, the workflow depended on repeated CSV preparation, manual part cleanup, duplicate checks, and uncertainty around whether a file had actually changed.

The process needed a controlled feed generator that could normalize parts, remove duplicates, publish stable outputs, preserve snapshots, and skip unchanged runs when appropriate.

System built

Built a stateful CSV workflow with part-number normalization, duplicate removal, stable output publishing, historical snapshots, SQLite state tracking, rotating logs, dry-run behavior, and audit summaries.

The system turns a recurring exclusion file into a repeatable feed automation with state, evidence, and cleaner downstream delivery.

Feed automation signals

Signals reviewed

The workflow reviews source readiness, normalized records, duplicate status, state changes, output paths, and run evidence before publishing the exclusion feed.

Exclusion feed flow

How it works

01

Read

Load recurring exclusion source files and prepare the records for normalization and validation.

The workflow starts with a controlled read layer so recurring CSV inputs are handled consistently instead of manually cleaned each run.

02

Normalize

Standardize part numbers, trim messy values, and prepare the feed for duplicate checks.

Part normalization protects the output from formatting drift and makes exclusion records easier to compare over time.

03

De-dupe

Remove duplicate exclusion records and preserve a clean feed structure before publishing.

The de-dupe layer keeps the outbound file stable and reduces repeated records that can create downstream confusion.

04

Compare

Check current inputs against stored state to decide whether the file changed or can be skipped.

State-aware processing prevents unnecessary output churn and makes recurring automation easier to trust.

05

Publish

Write stable published outputs, historical snapshots, logs, and audit summaries for review.

The final layer creates the usable feed file and the evidence needed to understand what happened during the run.

Automation layers

What the feed system coordinates

Normalization layer

Cleans part numbers and source values so repeated exclusion feeds follow a stable format.

State layer

Uses SQLite state tracking to identify changed and unchanged files across recurring runs.

Snapshot layer

Preserves historical run outputs so prior feed versions can be reviewed or compared.

Audit layer

Writes logs, dry-run evidence, and summary outputs that make the automation easier to support.

Impact signals

What the automation improved

Stable published exclusion feed outputs

Historical run snapshots for review and rollback context

Unchanged-file skip logic to reduce unnecessary processing

Part-number normalization and duplicate removal

SQLite state, rotating logs, dry-run behavior, and audit summaries

Operational value

Recurring exclusion files turned into a controlled feed process

Less recurring file prep

Turns repetitive exclusion feed creation into a repeatable automation instead of a manual CSV routine.

Cleaner exclusion records

Normalizes and de-duplicates part records so the published feed is easier to trust.

Change-aware processing

State tracking helps skip unchanged inputs and makes recurring runs more efficient.

Better supportability

Snapshots, logs, and audit summaries make it easier to answer what changed, what published, and why.

Why this project matters

Feed reliability improves when recurring CSV work has state, snapshots, and audit evidence.

This project shows how a simple recurring CSV file can become a controlled operational feed. Normalization, de-duplication, state tracking, snapshots, logs, and audit summaries help the workflow move from manual file prep to reliable automation.

The value is not just creating an exclusion file. The value is knowing what changed, what published, what was skipped, and how the feed can be reviewed later.
