CSV Cleanroom Tools

A practical bundle for freelancers, creators, agencies, support teams, and small businesses.

**Included**
- InvoiceForge — create invoices locally and print to PDF
- UTM Lab — build consistent campaign URLs and export a campaign matrix
- PII Shield — sanitize common sensitive values before sharing files

No accounts or network calls are required to run the included files. Each tool includes documentation, a commercial-use license, synthetic sample data where relevant, and tests. Review all generated output before using it in a business process.

Three privacy-first tools for invoices, campaigns, and safer data sharing.

Local Ops Toolkit — Offline Business Utilities

A local, review-first Python utility for developers, support teams, analysts, and consultants.

**Includes**
- Email, phone, SSN-shaped, valid test-like card, and IPv4 replacements
- New sanitized output file — the source is never overwritten
- Count-only JSON report with no original values stored
- Stdout mode for pipelines
- No network requests

Heuristic redaction is not a compliance certification and cannot guarantee that every sensitive value is found. Always review the sanitized copy.

Sanitize common sensitive values before sharing text, CSV, JSON, or logs.

PII Shield — Local Data Sanitizer

A local-first campaign URL builder for freelancers, creators, agencies, and small teams.

**Includes**
- Required source, medium, and campaign fields
- Optional campaign ID, platform, term, and content
- Lowercase and hyphen normalization
- Copy-to-clipboard and a small campaign matrix
- CSV export for launch handoffs

Open the HTML file in a modern browser. Campaign data stays local and is never uploaded.

Build consistent tracking links and catch campaign-tagging mistakes offline.

UTM Lab — Campaign URL Builder & QA

A standalone offline invoice workflow for freelancers and small teams.

**Includes**
- Seller and client details
- Line items with subtotal, tax, and total calculations
- USD, EUR, GBP, MXN, and CAD display
- Save/load JSON drafts
- Print or save as PDF from the browser

Open the HTML file in a modern browser. Your data stays in the tab and is never uploaded. This is a general productivity tool, not accounting, tax, or legal advice.

Create client-ready invoices locally, without subscriptions or uploads.

InvoiceForge — Offline Invoice Generator

Turn messy CSV exports into import-ready files in one local command.

CSV Cleanroom trims whitespace, normalizes emails and phones, removes blank rows and duplicate records, and writes a JSON report showing what changed. It runs on Python 3.9+, makes no network requests, and never uploads your data.

Included: a dependency-free Python utility, quick-start documentation, a synthetic sample CSV, a smoke test, and a commercial-use license.

Download the ZIP and run: python3 csv_cleanroom.py messy_contacts.csv

Your source CSV is never overwritten. Review the output before importing it elsewhere.
