Enterprise data processing and insights

This app orchestrates end-to-end ingestion, validation, consolidation, and publishing of enterprise data stored in shared folders. It auto-discovers relevant workbooks and tabs, standardizes heterogeneous structures, applies deterministic calculations and rollups, and produces executive-ready workbooks with role-based visibility, versioning, and multi-location saving. Everything is exposed through a lightweight web API so you can operate it from a UI or integrations.

What it does (key capabilities)

Source discovery: traverses corporate storage (Windows/macOS), finds valid files by pattern, de-duplicates, and tolerates naming drift.
Structured extraction: identifies "source" and "derivative" tabs, copies values + formatting while preserving validations and tab visibility.
Standardization & enrichment: cleans text, normalizes keys, and reconciles references across tabs (codes, catalogs, dictionaries) to join and summarize unambiguously.
Consistent calculations: populates summary tabs with governed formulas (to-date totals, category aggregations, indexing, numbering) ensuring cell-level traceability.
Governed publishing: creates outputs from a corporate template, enforces role-based visibility (e.g., analyst, leadership), versions ("V1", "V2"…), and writes to multiple business destinations.
Observable operations: JSON endpoints to list sources, generate full packages, update specific tabs, and audit non-allowed tabs; rich logging for diagnostics.

Flow

Discover & validate workbooks in standard corporate paths.
Detect tabs and copy values/formatting (styles, borders, validations).
Consolidate (useful-row filtering, joins to a master "BD", key-based grouping).
Assemble reports: build executive tabs with ready-to-recalculate formulas.
Publish: apply role visibility, normalize filenames, save to multiple locations, expose results via API.

Why it matters

It unifies spreadsheet silos into a repeatable, trustworthy pipeline, cutting manual errors (formatting/data), accelerating closes and reporting, and leaving an auditable trail from raw source to final KPI.

Where it fits (adaptable across industries)

Retail & CPG: consolidate product lists, price files, purchasing; category/vendor summaries.
Marketing & Sales: unify calendars, assets, codes, costs; campaign/channel rollups.
Operations & Supply Chain: catalogs, consumptions, progress; site/period trackers.
Financial Services / Telco / Healthcare: normalize internal templates, reconcile codes, deliver executive outputs with role access control.

Extensibility

Swap shared folders for SharePoint/Drive/S3.
Customize output templates and role visibility rules.
Add connectors to databases or export Parquet/CSV for BI.
Schedule runs and webhooks to plug into existing ETL/ELT.
