Ran OpenCart for six years and the extension ecosystem was dying. Every migration service I contacted wanted $3,000+ and two weeks of downtime. Exported my product catalog, ran the conversion, and the weight units converted from kg to grams automatically. Imported into Shopify on a Sunday evening and opened Monday morning on the new platform. Zero downtime.

How People Use OpenCart → Shopify
The scariest part of our OpenCart to Shopify move was the SEO metadata. We had spent two years writing custom meta titles and descriptions for every product. The converter mapped meta_title and meta_description straight to Shopify SEO fields. I did a full audit after import and every single SEO field transferred correctly. That alone saved us weeks of manual re-entry.
My OpenCart store used a third-party export extension that output semicolons in some fields and the status column was 1/0 instead of TRUE/FALSE. I tried importing directly into Shopify three times and it failed every time with parsing errors. The converter handled the status mapping and generated proper URL handles from my model numbers. First Shopify import after conversion worked perfectly.
OpenCart → Shopify Migration Questions
Does OpenCart have native CSV export?
OpenCart requires third-party extensions for CSV export (like Store Manager or Ka-Station). Ensure your export includes standard product fields.
What about customer data?
This tool migrates products only. Customer migration requires separate tools or services.
Will there be downtime during migration?
No, OpenCart remains fully operational during migration. Your store can continue processing sales on secure external servers while data transfers to Shopify.
Why OpenCart Products Don't Import Directly to Shopify
Field Name Incompatibilities
OpenCart uses model, name, price, quantity. Shopify uses Handle, Title, Variant Price, Variant Inventory Qty. Direct import fails with missing required columns.
Weight Conversion Needed
OpenCart exports weights in kilograms by default. Shopify requires grams. Incorrect conversion causes shipping calculation errors.
What This Tool Does
We transform your OpenCart export - Field mapping (model to Handle, name to Title), Weight conversion (kg to grams × 1000), Status mapping (status 1/0 to Published TRUE/FALSE), Handle generation (URL-safe slugs), UPC/EAN to Barcode mapping. Your Shopify import succeeds with proper formatting.
