Business problem

Weekly availability reporting needed consistent formatting, grouping, auditability, and distribution. Manual preparation made it harder to keep workbook layouts consistent, include validation context, and deliver reports to stakeholders on a repeatable schedule.

The process needed an automation utility that could locate the latest inventory file, organize the data into business-friendly groupings, generate audit-ready workbooks, and package the final report for delivery.

System built

Built a weekly inventory export automation with API and file routes, latest-file discovery, manufacturer and group normalization, value and discount rules, grouped workbook generation, standalone worksheets, audit tabs, timestamped ZIP creation, SMTP delivery, and failure-handling guardrails.

The system turns raw availability data into a repeatable reporting package that is easier to review, validate, distribute, and support.

Signals reviewed

The workflow evaluates source readiness, grouping logic, workbook coverage, audit outputs, package creation, and delivery status before the weekly report is complete.

Report generation flow

How it works

01

Collect

Pull or locate the latest inventory availability data through API routes or file-based inputs.

The workflow begins by finding the right source file or API extract so weekly reporting starts from the most current available data.

02

Normalize

Standardize manufacturer names, inventory groups, value fields, and discount logic before workbook creation.

Normalization makes the report easier to compare week to week and reduces downstream formatting cleanup.

03

Build

Generate grouped Excel workbooks, standalone worksheets, formatted tabs, and audit sheets.

The workbook layer packages inventory availability into review-ready sections rather than leaving users with raw exports.

04

Bundle

Create timestamped ZIP packages that include the workbook outputs and supporting audit files.

Bundling makes weekly distribution cleaner and gives stakeholders one controlled package instead of scattered files.

05

Deliver

Send stakeholder email delivery with attachments, failure handling, and delivery guardrails.

The delivery layer closes the loop by turning the generated report into a repeatable communication workflow.

Automation layers

What the weekly export coordinates

Source discovery

Finds the latest inventory extract or pulls availability data from API routes before report generation begins.

Grouping logic

Normalizes manufacturer and inventory group fields so workbook tabs and output sections stay consistent.

Workbook builder

Uses OpenPyXL to generate grouped workbooks, standalone worksheets, formatted sheets, and audit tabs.

Delivery layer

Creates ZIP bundles and sends stakeholder email delivery with status and failure-handling support.

Impact signals

What the automation improved

Grouped Excel workbooks for weekly inventory availability review

Audit sheet coverage for transparency and validation

Timestamped ZIP bundles for cleaner distribution

Stakeholder email delivery through SMTP automation

Failure notifications and guardrails for supportability

Operational value

Weekly availability reporting with audit-ready delivery

Less weekly manual reporting

Replaces repeat file prep, workbook formatting, packaging, and email delivery with a controlled automation flow.

Cleaner review packages

Groups inventory availability into stakeholder-friendly workbooks instead of sending raw exports.

Better auditability

Audit sheets and supporting files make the weekly report easier to validate and troubleshoot.

Repeatable distribution

ZIP bundling and SMTP delivery help weekly reporting arrive in a predictable, consistent format.

Why this project matters

Weekly inventory reporting works better when the report, audit trail, and delivery are one system.

This project shows how a routine weekly export can become a controlled reporting workflow. Data collection, normalization, workbook generation, audit sheets, ZIP packaging, and stakeholder delivery are coordinated into one repeatable process.

The value is not just automating an Excel file. The value is producing a weekly package that is easier to validate, distribute, and trust.
