# Shopify Matrixify The bulk-data workhorse of the catalog-cleanup suite. Matrixify moves store data in and out as spreadsheets, so it is how you touch thousands of records at once instead of one at a time in the admin. Almost every destructive mistake here comes from one of two misunderstandings: what a *blank cell* means, and what *omitting a row* means. Internalize the safety doctrine below before you touch a production catalog. Canonical docs: [matrixify.app/documentation](https://matrixify.app/documentation/). This skill is the operational playbook the docs don't spell out. ## Store access Matrixify runs inside the store, not through the Admin API. You do the work in two places: - **The Matrixify app** (Shopify admin → Apps → Matrixify): run Export to pull a sheet, run Import to push one. Every import shows an **Analyze** preview and, after it runs, an **Import Results** file. - **A spreadsheet** you edit locally (Excel or any CSV editor) or generate with throwaway code. No token lives in this skill. To verify a write landed, re-export the affected records and inspect the cells, or read them back through the Admin API: the storefront is CDN-cached and lies about freshness. ## Safety doctrine Read this section twice. Every rule here was learned by someone breaking a live store. 1. **Back up first: the export IS the backup.** Before any bulk write, run a full export of the entity you're about to touch (Products, Collections, etc.) and save the file.
