A Microsoft Excel add-inProduct catalogs, into
your retailer Excel templates.
AI reads product catalogs and technical spec sheets (PDF, Excel, images) and automatically drafts your retailer-mandated Excel formats. Pre-register any custom retail or marketplace template on demand — with every single value traceable back to its source document.
An add-in is an extension you add to the Excel you already use. ZAG opens a pane on the right of Excel and drafts your registration sheets in place. One-minute install; your files and your Excel stay exactly as they are.
No application needed. 1 SKU = 1 credit = ¥30, no subscription, and your first 50 SKUs are free.

Nothing new to learn.
Excel gets one extra pane.
Add the add-in to Excel
Add ZAG to Excel in Microsoft 365 (desktop or web). One minute, no IT involvement.
A ZAG pane opens on the right
Open a retailer's registration format as usual and ZAG recognises it. Add your catalogs and spec sheets to the pane.
Name the products, get the draft
Tell it the JANs or model numbers and the sheet's cells fill in. Every value is one click from its source.
The product data exists.
Registration is where it stalls.
To list products with retailers and marketplaces, suppliers must conform to each channel's proprietary registration template. Hundreds of required columns, category taxonomies, character limits, code systems, and dropdown constraints — unique to every sheet.
The same product specifications get retyped manually into one spreadsheet after another. Transcription errors come back as costly rejections, time-to-market is delayed, and onboarding depends on rare spreadsheet experts.
Three steps,
all inside Excel.
Read
Complex multi-column layouts, technical spec sheets, footnotes, schematics, and fragmented PDFs. This isn't general document summarisation — it is engineered to extract exact structured attributes: for each model number, which specification takes which value?
Review
Extracted attributes populate a ZAG Review Sheet first. Operators inspect values side-by-side with source documents and adjust only what needs correcting. Because every cell links to its exact source, verification is comparing — not hunting.
Fill
Processing runs across your entire product list in bulk, not row by row. Confirmed fields are filled; attributes lacking solid evidence are left blank with reasons attached. Not guessing is the shortest path to zero retailer rejections.
Your retailer templates,
onboarded and verified.
26 formats across 13 retailers and marketplaces are pre-registered today — consumer electronics chains, marketplaces, industrial supply and sports retail. We onboard your own retailer or marketplace templates on demand, and every template is tested against real-world catalog data before deployment.

How this differs from
Copilot and Claude Cowork.
Both are capable general-purpose work tools. But product master data is work where being able to check the result afterwards is the whole point. That single requirement changes the design.
| Dimension | General office AI | ZAG for Excel |
|---|---|---|
| Template spec | Re-interprets the sheet each run, so output drifts | Per-retailer specs registered and verified; same input, same result |
| Provenance | No general way to trace a value to its source | Source reference per cell, cross-checked in a review sheet |
| Unknown fields | Can fill with a plausible-looking value | Left blank with a stated reason — never guessed |
| Unit of work | Driven by whatever you specify each run; hundreds of columns and SKUs depend on how well you prompt it | Designed around batch runs over a product list |
| Validation rules | Easily violates length limits, code systems, dropdowns | Generates and checks against the registered rules |
Running securely
on Microsoft Azure.

| AI platform | Azure OpenAI Service. Under Microsoft's published terms, your data is never used to train foundation models. |

1 SKU = 1 credit = ¥30. No subscription.
Your first 50 SKUs are free. After that you buy credits and spend one each time a SKU is actually written. There is no monthly fee, no seat charge and no plan to pick.
| SKU credits | ¥30 per SKU (1 credit, tax included) |
|---|---|
| Free trial | Your first 50 SKUs — granted once at registration, no time limit, no card required |
| Subscription | None |
| Seats | Unlimited — nothing is charged per user |
| Templates | Every pre-registered template is included |
| Custom format setup | Quoted individually based on template complexity |
| Requirements | Microsoft 365 (Excel desktop or web) |
| Credits | You pay | Off | Per SKU |
|---|---|---|---|
| 1–99 | ¥30 × n | — | ¥30 |
| 100 | ¥2,700 | 10% | ¥27 |
| 500 | ¥12,750 | 15% | ¥25.5 |
| 1,000 | ¥24,000 | 20% | ¥24 |
| 10,000 | ¥210,000 | 30% | ¥21 |
One credit is one SKU written. Credits are bought up front, in packs of 100, 500, 1,000 or 10,000 — or any amount you choose; 700 credits buy at the 500 tier. Re-filling a SKU you already filled this month costs nothing, so corrections and second passes are free. If the balance will not cover a fill, we say so instead of running it.
Custom template onboarding is quoted per format before your rollout starts. High-volume and dedicated tenant deployments are quoted individually. Payment by credit card or Japanese bank transfer. Prices include Japanese consumption tax. See the Terms of Service for contract conditions.
