😩 The problem
You're running a marketplace. Every new seller needs to upload their product catalog — but every seller has their own format. Different column names, different category structures, different EAN formats, different price conventions.
Your technical team builds custom importers. Your ops team manually reformats files. Your sellers wait days before their products are live. Some give up before they even start.
And every time you update your catalog format, the whole process breaks again.
✅ How WeTransform solves it
You configure your catalog format once — with all your column requirements, valid categories, mandatory fields, and constraints. Sellers upload whatever they have. WeTransform guides them through the transformation to your format, corrects errors interactively, and delivers a clean, validated catalog ready for ingestion.
No custom importer. No manual reformatting. No back-and-forth emails.
🛍️ What the seller experience looks like
Your new seller logs into your platform and clicks "Upload your catalog". They see an interface — embedded in your platform, with your branding — where they upload their file.
They upload their product file — whatever format they export from their own system
WeTransform's AI automatically maps their columns to yours ("Prix HT" → "price_excl_tax", "Réf article" → "sku", etc.)
If their categories don't match yours, the AI maps them — and the seller can review and correct
Missing fields are flagged clearly, with suggestions on how to fix them
They submit — your system receives a fully validated catalog
🌟 Fill the Gaps for incomplete catalogs. If a seller's catalog has hundreds of missing attributes — product type, dimensions, weight — WeTransform's AI can infer and fill them automatically from the product description. Sellers submit complete catalogs even when their source data is sparse.
⚡ For sellers who want to automate
Once a seller's transformation is configured, they can connect their own feed (FTP, URL, API) and set a schedule. Their catalog updates automatically — daily, weekly, or on demand — without any manual upload.
Your marketplace receives fresh, validated data on autopilot.
