Should I validate the catalog before uploading?

Absolutely. A pre-upload validation (dry-run) catches errors before they impact your store: missing columns, invalid prices, duplicate handles, inaccessible images. Seegea offers a dry-run with a detailed report before any push.

How do I upload a PrestaShop catalog from a supplier XML file?

PrestaShop only accepts CSV in native import. For a supplier XML, you must first convert it to CSV (via XSLT script, Python, or a tool like Seegea) by mapping XML nodes to PrestaShop columns, then import the resulting CSV.

Can I monitor the progress of an ongoing upload?

Native Shopify and PrestaShop imports show a progress bar but cannot resume after interruption. The Shopify API Bulk Operations provides a webhook when the operation completes. Seegea displays real-time status and allows resuming an interrupted import.

What if an upload created errors on existing products?

Without rollback, you must identify affected products (via post-import CSV export) and fix them manually. With Seegea, each imported product has a saved version. A Ctrl+Z or a click on Restore goes back to the pre-import state and re-pushes to Shopify.

Product catalog upload: the clean way to publish a large catalog

A successful catalog upload follows four steps in order: prepare the file, validate with a dry-run, upload to production, monitor and fix. Skipping the validation phase means risking 48 hours of damage control afterward.

The 4 steps of a stress-free catalog upload

1. Prepare and clean the file

Check encoding (UTF-8), separators, required columns, accessible image URLs. A CSV validation tool (CSVlint, Excel with formulas) identifies 80% of errors before upload.

2. Dry-run: validate without pushing

Seegea offers a dry-run mode that analyzes the file, simulates the import and generates a report: valid rows, rows with errors, detected duplicates, inaccessible images. Zero impact on the store.

3. Production upload with monitoring

Progressive push with real-time log. If an error occurs mid-upload, Seegea stops and lists the problematic rows. Already imported products are versioned and restorable.

Feature	Native Shopify import	Matrixify	Seegea
Dry-run before upload	No	Partial	Yes, full report
Real-time monitoring	Progress bar	Yes	Yes + per-row log
Post-upload rollback	No	No	Ctrl+Z per product
AI enrichment during upload	No	No	Yes (descriptions + images)
Reliable max volume	15k CSV rows	100k+ rows	100k+ SKUs

Before any production catalog upload: enable Shopify maintenance mode (Online Store → Preferences → Enable password page). Your customers will not see partially imported products during the operation.

Uploading XML to Shopify or PrestaShop

Supplier files often arrive as XML (ERP feeds, wholesale catalogs). Neither Shopify nor PrestaShop accepts XML in native import. Conversion steps:

Parse the XML with an XSLT sheet or a Python script (ElementTree)
Map XML nodes to the target CSV columns
Validate the resulting CSV before upload
Import the CSV into Shopify or PrestaShop

Seegea simplifies this workflow with a visual XML-to-CSV mapping: you select source nodes and target columns in a drag-and-drop interface, no code required.

Built in France between Annecy and Chantilly, Seegea supports every catalog upload with Google Meet support and full rollback if anything goes wrong.

FAQ

Shopify accepts CSV files up to 50 MB. For images, they are fetched via URL during import (no direct image upload in CSV). If your file exceeds 50 MB, split it into multiple files or use the API Bulk Operations.
