Inventory Loader Flat-File Generator

Building an Inventory Loader file by hand means wrestling with tabs, column order, and operation codes across hundreds of rows. Paste your data as CSV or tab-separated text, pick the template type, and download a properly tab-delimited draft using Amazon's classic column names. Important: Amazon's templates vary by category and marketplace, so always compare the draft against the template you download from Seller Central before uploading.

Draft file: compare the header row against the template you download from Seller Central (Inventory → Add Products via Upload) before uploading — columns vary by category.

Why build your Amazon Inventory Loader file this way?

Bulk-uploading products through Seller Central's Inventory Loader beats adding listings one by one — but hand-building the tab-delimited file is where errors creep in: a stray comma, a misaligned column, a missing product ID. An Amazon inventory management Excel template helps, but only if every row follows the format exactly.

This generator handles the mechanical part: delimiter detection, tab-delimited output, and Amazon's standard column names. You handle the judgment part: checking the draft against the official template from Seller Central (Inventory → Add Products via Upload) before you upload. The output is always a draft to verify — never presented as upload-ready on its own.

How do I build an Amazon Inventory Loader file?

From a pasted table to a downloadable draft:

  1. Paste your rows as CSV or tab-separated text: SKU, price, quantity, product ID (and optionally product-ID type and condition).
  2. Choose the template type — full Inventory Loader or a price-and-quantity update — plus the operation (add or delete).
  3. Hit Generate to preview the tab-delimited draft and download it as a .txt file.
  4. Compare the header row against the template you download from Seller Central (Inventory → Add Products via Upload), then upload.

Treat it as a draft. It uses Amazon's classic Inventory Loader column names, but Amazon's templates vary by category and marketplace. Always compare the header row against the template you download from Seller Central before uploading.
Seller Central's bulk upload reads a tab-delimited Amazon inventory file row by row — each row is a SKU with its price, quantity, and product identifiers. Amazon validates the columns against the template, then creates or updates your listings. This tool builds that file's draft so the structure is right before you verify it against the official template.
Add creates or updates the offer for that SKU; delete removes the offer. Double-check every row marked for deletion before uploading — deletions take the offer down.
That question is about Amazon's accounting — how it values FBA inventory for settlements — which is separate from the flat file this tool builds. The file lists and updates your products, quantities, and prices; Amazon documents its current valuation method in Seller Central help, so check there for the latest version since policies change.
Nowhere. The file is generated inside your browser tab and downloaded directly to your computer. Your SKU data never touches our servers.
