Why Shopify Products Need Conversion for Shift4Shop

Image Column Structure Mismatch

Shopify exports multiple rows when products have multiple images. Shift4Shop uses image1, image2, image3, image4 columns in single row. Direct upload only imports first image or creates duplicates.

Weight Unit Incompatibility

Shopify: Weight in grams (metric). Shift4Shop: Weight in pounds (imperial). 1000x conversion error breaks shipping calculations.

What This Tool Does

We automatically convert your Shopify export: - Row Aggregation: Multiple Shopify rows → single Shift4Shop row - Image Distribution: Collect images into image1/2/3/4 columns - Weight Conversion: Grams to pounds (÷ 453.592) - Price Mapping: Compare At → retail, Variant Price → price - Field Mapping: All Shopify fields → Shift4Shop columns Your Shift4Shop import succeeds with proper image distribution and weights.

Frequently Asked Questions

It depends on your needs. Cart2Cart is built for businesses that need advanced automation and accounting integrations. If you're a small business doing monthly imports or occasional conversions, SpreadsheetBroccoli's simpler approach may be a better fit - no subscriptions, no setup, just results.
Not for the same transactions - you'd risk double-counting. However, you could use Cart2Cart for ongoing automation and SpreadsheetBroccoli for one-off historical imports or quick ad-hoc conversions outside your normal workflow.
Cart2Cart typically requires 30-60 minutes of initial setup (account creation, API connections, mapping configuration), then runs automatically. SpreadsheetBroccoli takes under 2 minutes per conversion - upload, preview, download. Choose based on whether you need ongoing automation or quick occasional conversions.
Pick a clean cutoff date (end of month works best). Let Cart2Cart finish processing that period, then disconnect. Export your data from the source platform and use SpreadsheetBroccoli for conversions going forward. The first month needs careful reconciliation to ensure no gaps or duplicates.
Both produce accurate results when used correctly. Cart2Cart uses API connections for automated data sync. SpreadsheetBroccoli processes the exact file you provide and shows you a preview before finalizing. Our pre-upload validation catches errors before they reach your accounting software.
Cart2Cart typically charges monthly subscriptions regardless of usage. SpreadsheetBroccoli offers flexible options: free preview before commitment, pay-per-conversion, credit bundles for volume, or subscriptions for heavy users. You only pay for what you actually use.
Cart2Cart offers various support tiers depending on your plan. SpreadsheetBroccoli provides fast email support to all users. Our file-based approach also means simpler troubleshooting - if something looks wrong, you can see exactly what data was converted in the preview.
Cart2Cart processes data on their servers via API connections. SpreadsheetBroccoli processes files entirely in your browser - your data never leaves your device. There's no account to hack, no API tokens to secure, and no data stored on external servers.
SpreadsheetBroccoli is ideal for small businesses doing their own bookkeeping, occasional users who need monthly or quarterly imports, and anyone who wants instant results without learning a new platform. Cart2Cart is better suited for larger operations with dedicated bookkeepers who need ongoing automation.
Cart2Cart offers automated syncing, real-time connections, and features like multi-channel consolidation or advanced accounting automation. SpreadsheetBroccoli focuses on doing file conversion exceptionally well - fast, private, and simple. We're not trying to replace full accounting platforms, just make conversions effortless.
Absolutely not. This is a major security advantage of SpreadsheetBroccoli over Cart2Cart. Cart2Cart requires you to hand over API keys or login credentials, creating a permanent security vulnerability. We only touch the specific file you upload, process it in your browser, and forget it immediately.
It works until it breaks. Automated integrations often fail silently when platforms update their APIs, leaving you with weeks of missing or duplicated data to clean up manually. SpreadsheetBroccoli is deterministic: you verify the file right now, import it right now, and you know it's done correctly. It turns "background anxiety" into "finished work."
You can, but the cost is validation and edge cases. AI often hallucinates math or format structures, and free scripts rarely handle messy real-world data (missing SKUs, strange currency formats, tax anomalies). We have battle-tested validators specifically for Cart2Cart exports that catch issues a generic script will miss.
