I run Matrixify every working day: bulk product and order imports, tag and variant commands, metafield migrations, image cleanup and full platform migrations — on live stores, without breaking the catalog.

Four stores, four verticals, and behind each one the same unglamorous discipline: clean catalog data.
Matrixify (formerly Excelify) is the Shopify app that turns your entire store into a spreadsheet and back again. Products, variants, inventory, collections, customers, orders, draft orders, discounts, metafields, translations, redirects, pages and blog posts all export to Excel, CSV or Google Sheets, get edited in bulk, and import back with far more control than Shopify's native CSV importer gives you. If you have ever needed to change one field across 40,000 variants, you already know why it exists.
The reason to hire a Matrixify expert rather than learning it yourself is that the app is genuinely powerful, which also means it is genuinely capable of destroying a catalog. An import with the wrong Command column can overwrite prices across the store. A missing Variant ID can duplicate every variant on every product. Matrixify itself is careful and gives you an undo path on many jobs, but the fastest way to find the edge cases is on production, at 4pm, before a sale.
I operate two storefronts — B2C and B2B — for a US manufacturer, keeping a multi-level variant catalog synchronised across 7+ sales channels with MAP and MSRP pricing rules that differ per channel. Matrixify is the backbone of that operation. My Shopify experience goes back 6+ years and started with my own store, Martin (martin4shop.com.br), where I did the catalog work myself across 1,959 orders because there was nobody else to do it.
Bulk product upload to Shopify across thousands of SKUs — titles, descriptions, vendors, types, pricing, SEO fields and status. I always match on Handle or Variant ID rather than title, run a NEW-only pass before a full update, and keep the pre-import export as a rollback file.
Historical orders brought in from another platform or from a spreadsheet, with line items, taxes, shipping, financial and fulfilment status preserved. Critical during migrations so your finance and support teams do not lose two years of history. Imported without triggering customer notifications.
The Tags Command column is the single most useful and most dangerous field in Matrixify. MERGE adds tags without touching what is already there; leaving it blank silently replaces the whole tag set. I use it to run collection logic, channel eligibility and merchandising rules across the catalog safely.
Adding, reordering, renaming and removing variants and option values in bulk — including restructuring multi-level option sets without orphaning inventory or losing variant IDs. This is where most DIY imports go wrong and where a careful staging pass pays for itself.
Bulk creation and migration of product, variant, collection and customer metafields with the correct namespace, key and type — including moving legacy metafields into Online Store 2.0 definitions and metaobjects so your theme can actually render them.
Smart and manual collections created and updated in bulk, with rules, sort order, SEO fields, images and product membership. Combined with tag work, this rebuilds a whole merchandising structure in one pass instead of hundreds of clicks.
Bulk image upload from URLs, reordering, alt text for accessibility and SEO, assigning images to specific variants, and removing duplicates. Alt text alone is one of the cheapest SEO wins available on a large catalog.
Translated content exported, edited in bulk and reimported for multi-language stores, keeping product, collection and theme translations consistent across markets instead of drifting file by file.
Scheduled recurring imports from a supplier feed or a Google Sheet to keep inventory levels, costs, compare-at pricing and channel-specific price rules current across locations without a person retyping numbers.
Matrixify is the cleanest path off most legacy platforms because it preserves the data model instead of flattening it. I use it for full migrations and for the messy partial ones.
Shopify is rarely the only place your product data has to live. I syndicate catalogs out to national US retailers and manage the source of truth in Salsify PIM, which is a different discipline from uploading a CSV to a store.
Matrixify is one tool in a wider catalog operation. The rest of the job is keeping the data correct once it is in.
Nothing gets imported before I have exported. The current state becomes both the audit source and the rollback file, and the audit usually surfaces problems the client did not know existed — duplicate SKUs, wrong option names, products invisible on a channel.
The import sheet is built and run against a development store or a small slice of production so the mapping is proven before it touches the real catalog. Counts are compared and edge cases are spot-checked manually.
Real imports go in batches, not all at once, scheduled outside peak hours. I watch the Matrixify job log for every batch and stop at the first unexpected result rather than discovering it 30,000 rows later.
After the import I verify counts, storefront rendering, channel publication and search indexing, then hand over the sheets, the mapping notes and the rollback files so your team can repeat the process without me.
Matrixify, formerly called Excelify, is a Shopify app for bulk import and export of store data using Excel, CSV or Google Sheets. It handles products, variants, inventory, collections, customers, orders, draft orders, discounts, metafields, translations, redirects, pages, blogs and more — far beyond what Shopify's built-in CSV import supports. It is the standard tool for large catalog edits, platform migrations and scheduled data syncs.
Matrixify is billed by Shopify as a monthly subscription tiered by how many rows you import and export per month, with a free tier for very small jobs and higher plans for large catalogs and migrations. The app fee is paid by you directly to Shopify, separate from my fee. For a one-off migration it is common to subscribe to a higher tier for a single month and step back down afterwards, which I will tell you how to do.
Use the native importer for simple product creation on a small catalog. Use Matrixify when you need to update existing records rather than replace them, when you are touching metafields, orders, collections or translations, when you need commands like MERGE on tags, when the job is large enough that partial failure matters, or when you need a scheduled recurring import. The native importer also silently overwrites fields you leave blank, which is a common way to wipe data by accident.
Risky enough to justify a process. Every job I run starts with a full export as a rollback file, gets tested on a development store or a ten-row slice first, runs in batches outside peak hours, and is monitored row by row in the job log. Matrixify itself supports an undo on many import types, but undo is a safety net, not a plan. I have never had to restore a client catalog from a rollback file, and I still make one every time.
Ad-hoc Matrixify and catalog operations run US$60 to US$90 per hour. A defined job — a migration, a metafield restructure, a catalog audit with fix files — is quoted fixed-price from a look at your export first. Ongoing catalog operations are a monthly retainer with an agreed hour block, which is what most clients with a large or fast-changing catalog end up on.
I am in São Paulo, UTC-3, one to two hours ahead of US Eastern, so a normal US business day gives four to six hours of live overlap. Large imports run in your store's quiet window, typically overnight your time, which is my morning — so someone is awake and watching the job log while it runs rather than reading the failure the next day.
Yes to a written contract and NDA on every engagement, including yours instead of mine. Catalog and customer exports are sensitive commercial data: they are stored encrypted, never shared, and deleted once the work is verified. All sheets, scripts, mapping documentation and audit tooling I build for you are yours on payment, and your team can keep running them without me.
Send me an export, or just describe the mess. I will tell you whether it is a one-hour Matrixify job or a two-week operation — free.
