What Goes Wrong in an Ordinary Working Day

Warehouse teams update quantities in shared Google Sheets, but copy-pasting numbers directly into WooCommerce without verifying stock deltas leads to accidental overselling or overwriting live prices.

The Impact on Your Business & Customers

Syncing mismatched spreadsheets directly to a live store causes unfulfillable orders and incorrect customer charges.

What This Tool Does & What Changes for You

Reads your warehouse Google Sheet export and WooCommerce product CSV, aligns matching SKUs, computes quantity and price deltas, and isolates any missing items into a clean preview file.

What Changes in Practice:

You see exactly what will change before any data touches your store, eliminating blind spreadsheet imports.

Concrete Before & After Example (Actual Code Output)

Demonstrates how the delta preview isolates warehouse changes without blindly overwriting your live store.

INPUT: Google Sheet vs WooCommerce ExportInput File
[Google Sheet (Warehouse)]: SKU-101, Stock: 25, Price: 49.00
[WooCommerce (Live Store)]: SKU-101, Stock: 5, Price: 45.00
OUTPUT: sync_preview_delta.csvnormalized_inventory.csv
sku,store_stock,sheet_stock,stock_delta,store_price,sheet_price,price_delta,action
SKU-101,5,25,+20,45.00,49.00,+4.00,UPDATE_STOCK_AND_PRICE

Clear actionable row showing exact differences. You review the delta before applying it to WooCommerce.

What Changed vs. What Remained Unchanged

✓ What Changed (Normalized):
  • Identified exact stock delta (+20 units) and price change (+₹4.00)
  • Separated unmapped SKUs into missing_skus_report.csv
  • Generated clean CSV formatted for WooCommerce Product CSV Importer
ℹ What Remained Unchanged:
  • Zero direct changes made to your live WooCommerce database during preview
  • Original Google Sheets and WooCommerce CSV files are preserved

What You Need Before Getting Started

  • WooCommerce product export CSV
  • Python 3.10+ on your machine
  • Optional: a small SQLite DB for caching (bundled, no extra install)

Frequently Asked Questions

Why use a CSV dry-run instead of direct live API sync plugins?

Direct live sync plugins often overwrite healthy stock levels on accidental bulk edits or when formula errors occur in spreadsheets. This toolkit generates a dry-run preview report and clean verified CSV, guaranteeing zero accidental store overwrites.

Does this tool require paid API subscriptions or Zapier?

No. It runs entirely on your local machine using Python's standard library with zero third-party software subscriptions or monthly fees.

How are duplicate SKUs handled?

The script scans your inventory sheet and identifies colliding SKUs, reporting line numbers so you can resolve catalog duplicates before importing to WooCommerce.

Can I use this with Microsoft Excel instead of Google Sheets?

Yes. Any spreadsheet tool capable of exporting standard UTF-8 comma-separated (CSV) files works seamlessly.
