Why Shift4Shop Products Don't Import Directly to Shopify

Weight Unit Mismatch

Shift4Shop exports weights in pounds. Shopify requires grams. Direct import causes shipping calculation errors or validation failures.

Field Name Differences

Shift4Shop uses id, name, price, stock. Shopify uses Handle, Title, Variant Price, Variant Inventory Qty. Column mismatches prevent successful import.

Sale Price Logic

Shift4Shop has onsale flag and saleprice column. Shopify uses Variant Price and Variant Compare At Price. Different pricing logic requires transformation.

What This Tool Does

We transform your Shift4Shop export - Handle generation from id/SKU, Weight conversion (lbs to grams × 453.592), Sale price mapping (saleprice to Price, price to Compare At), Hide status inversion (hide true/false to Published TRUE/FALSE), Image mapping (image1-4 to Image Src), GTIN/UPC/EAN to Barcode, Categories to Tags. Your Shopify import succeeds with proper data.

Frequently Asked Questions

It depends on your needs. CartCoders 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 CartCoders for ongoing automation and SpreadsheetBroccoli for one-off historical imports or quick ad-hoc conversions outside your normal workflow.
CartCoders 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 CartCoders 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. CartCoders 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.
CartCoders 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.
CartCoders 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.
CartCoders 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. CartCoders is better suited for larger operations with dedicated bookkeepers who need ongoing automation.
CartCoders 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 CartCoders. CartCoders 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 CartCoders exports that catch issues a generic script will miss.
