Automatically detects columns, cleans your data, shows you a preview, and publishes to Shopify without errors. In less than a minute.
Free 7-day trial. Plans from $9.99/mo.
Silent failures & broken headers
It says 'success' but nothing changes. Headers are case-sensitive — one typo breaks the whole import.
No Excel. Blank columns erase data.
Only rigid CSV accepted — no Excel. Empty columns silently wipe existing product data without any warning.
Cryptic errors & 15 MB limit
Error messages don't tell you which field or row failed. And the 15 MB cap forces you to split files by hand.
Upload your CSV or Excel as-is
Drag and drop the file exactly as you received it. No reformatting, no renaming, no prep work.
AI detects every column
Shelvio uses AI to identify what each column is — price, title, SKU — even in other languages or without headers.
Preview, adjust, and publish
Review the preview, tweak anything you want, then click publish. Clean products in Shopify.
AI column mapping
Recognizes columns even when they're in another language or there are no headers at all.
Native Excel support
No more 'save as UTF-8 CSV'. Upload your .xlsx directly and Shelvio handles the rest.
Auto-cleaning & $9.99/mo
Encoding, smart quotes, leading zeros in SKUs — all fixed automatically. Plans from $9.99/mo, flat price.

Shelvio turns a supplier's CSV or Excel file into clean Shopify products without reformatting. Below, the exact answer to each common question.
Upload your CSV to Shelvio exactly as your supplier sent it — no reformatting. Shelvio's AI reads your columns, maps them to Shopify fields, cleans the data, and shows a preview before publishing. You never rename headers or match a template.
Shelvio imports Excel (.xlsx) files natively — you don't convert them to CSV first. Drag your spreadsheet in as-is; the AI detects each column and publishes clean products to Shopify. Shopify's built-in importer only accepts CSV, so this removes a manual conversion step.
With Shelvio you skip Shopify's CSV template entirely. Instead of forcing your file into fixed column names, the AI works out what each column means, so any supplier file imports without prep. That is the core difference from Shopify's built-in importer, which rejects files that don't match its exact format.
Shelvio maps columns automatically with AI — it identifies price, title, SKU, description and more, even when headers are unusual or missing. You can adjust any mapping in the preview, and Shelvio saves it per supplier, so the next file from that supplier maps instantly.
Yes. Shelvio's AI detects columns regardless of the language of your headers or data, so a supplier catalog in Spanish, French, German or another language maps to Shopify without you translating column names by hand.
On the Ultra plan, Shelvio updates existing products in bulk using Shopify Bulk Operations, matching them by SKU, handle or barcode. Upload a supplier file with new prices or stock levels and Shelvio updates the matching products — no editing product by product.
Shelvio has two plans: Pro at $9.99/month and Ultra at $19.99/month. Both include a 7-day free trial.

If you need a full data migration and export suite for your whole store, Matrixify is more powerful. If you just want to turn a supplier's product file into clean Shopify products without reformatting, Shelvio is faster and cheaper for that job.
