amztool Review: Build Amazon Sponsored Products Bulk Sheets in Minutes, Not Hours

Anyone who has hand-built an Amazon Sponsored Products bulk sheet knows the pain: Amazon's official 30-column format is unforgiving, and one misaligned column can break an upload. amztool replaces that manual spreadsheet work with a visual campaign builder that outputs upload-ready bulk sheets directly.

What Is amztool?

amztool is a lightweight, browser-based tool for building Amazon Sponsored Products campaigns visually and exporting them in Amazon's official bulk sheet format. Instead of formatting Excel files by hand or building campaigns one-by-one in Seller Central, sellers set up targeting logic in a visual interface and export a ready-to-upload .xlsx file. A companion open specification on GitHub documents the underlying bulk-sheet schema for developers who want to understand or extend the format.

Key Features

Visual campaign builder. Sellers construct Sponsored Products campaigns through a point-and-click interface rather than manually populating spreadsheet columns.

Full match-type support. Keyword targeting covers exact, phrase, and broad match types, alongside ASIN targeting for competitor and complementary product placements.

Auto targeting with bid control. Adjustable bids across auto-targeting match categories (close match, loose match, substitutes, complements) give sellers granular control without manual formula-writing.

Negative keyword and ASIN management. Built-in tools for excluding irrelevant search terms and competitor ASINs from campaigns.

Reusable dictionaries. SKUs, portfolios, and keyword groups can be saved and reused across campaigns, cutting down repetitive setup work for sellers managing many SKUs.

Auto-save and edit history. Work is saved automatically, with the ability to restore previous edits if a campaign plan changes mid-build.

Official format export. Output matches Amazon's official 30-column bulk sheet format, ready for direct upload to Seller Central or Advertising Console.

Who amztool Is For

amztool is positioned for sellers who already understand their PPC strategy — keyword lists, bid logic, targeting structure — but want to eliminate the technical friction of translating that strategy into Amazon's bulk sheet format. It's explicitly a "focused, lightweight tool" rather than a full analytics suite, making it a good fit for sellers or PPC specialists who want speed on the campaign-building step specifically, while handling performance analysis elsewhere.

Pricing

• Free: 12 bulk sheet generations per month
• Basic: $9.90/month for 70 generations
• Pro: $19.90/month for unlimited generations

No credit card, Amazon account connection, or API integration is required to use the tool, and it works across all major Amazon marketplaces globally.

Strengths and Considerations

The core strength is speed: the site claims sellers can build 200 Sponsored Products campaigns in around 10 minutes, a dramatic reduction from manual spreadsheet work. Because amztool doesn't connect directly to a seller's Amazon Advertising account, there's no API integration risk, but that also means sellers still need to manually upload the exported file and monitor performance elsewhere — amztool builds the campaign structure, it doesn't manage or optimize it after launch. The open GitHub spec is a nice trust signal for technically-minded users who want to verify exactly what the bulk sheet format includes before uploading.

Frequently Asked Questions

Does amztool connect to my Amazon Advertising account? No — amztool builds campaign files locally that you export and upload yourself, without any Amazon account or API connection.

What does amztool cost? Plans range from a free tier (12 generations/month) to $19.90/month for unlimited bulk sheet generations.

Does amztool manage campaigns after they're uploaded? No — it's a campaign-building tool, not an ongoing optimization or bid-management platform. Once uploaded, performance management happens in Seller Central or a separate PPC tool.

Is there documentation on the bulk sheet format amztool uses? Yes, an open specification is available on GitHub describing the schema.

Bottom Line

For sellers who already know their PPC targeting strategy and just want to eliminate spreadsheet formatting errors, amztool is a fast, low-cost way to go from campaign plan to upload-ready file — just pair it with a separate reporting or bid-management tool for ongoing optimization.
