Frequently asked questions

What is Shelvio?

An AI-powered CSV/Excel importer for Shopify. Upload a supplier file in any format and Shelvio maps the columns, cleans the data, and publishes products — no manual template required.

What file formats does Shelvio support?

CSV, XLSX, and XLS.

Does the file need to match a specific template?

No. That's the whole point — Shelvio adapts to your file, not the other way around.

How long does an import take?

Small imports finish in seconds. Larger catalogs (via Bulk Operations) typically finish within a few minutes, depending on size.

What's the difference between Pro and Ultra?

Pro covers standard imports with per-import and weekly limits. Ultra is unlimited and adds Bulk Operations (for large catalogs) and Update mode (updating existing products instead of only creating new ones).

Can Shelvio update products I already have, instead of creating duplicates?

Yes, with Shelvio Ultra's Update mode — match by SKU, handle, or barcode.

Will Shelvio overwrite data I don't want touched?

Only the fields you map are affected. You see a full preview before anything is published or updated.

Is there a free trial?

Yes — 7 days on both plans, no charge until the trial ends.

Can I cancel anytime?

Yes, from the Shopify billing settings at any time.

Is my data secure?

Files are processed to build your product import and are not shared with third parties. Column mapping uses Anthropic's Claude AI to analyze headers and sample values.

What languages does Shelvio support?

The app interface is available in English and Spanish. Uploaded files can be in any language — the AI mapping isn't limited by language.

How is Shelvio different from Matrixify?

Matrixify is a broader, more feature-heavy import/export tool. Shelvio is focused specifically on fast, zero-template CSV/Excel imports with AI-driven mapping — built for merchants who want to upload a supplier file as-is and get clean products, without learning a template format first.

I found an error in my import — what do I do?

Check the import history in the app dashboard for a per-row error summary, or email support@shelvio.net with your import date and the file if possible.
