Flat File Upload to Amazon: A Step-by-Step Guide

Step 1: Pick the Right Template

Amazon provides various templates to choose from based on the product category. These templates save you time and help maintain consistency in your product listings.

In FlatFilePro, we offer a range of templates catering to your specific needs. Simply review the available options and select the most appropriate template for your product category.

Step 2: Collect Your Product Data

Before you start filling in the template, assemble all the necessary product data. This may include:

  • Product name
  • Brand
  • Manufacturer
  • Product description
  • Bullet points (key features)
  • Images
  • SKU, EAN, or ASIN

Organizing your data beforehand will streamline the flat file creation process.

Step 3: Input Your Data in FlatFilePro

With your data ready, start populating the fields provided in the FlatFilePro template. Be careful to maintain consistency across your listings by adhering to Amazon’s formatting guidelines.

Step 4: Validate Your Flat File

As you fill in the data, FlatFilePro automatically validates it to ensure it follows Amazon’s rules (e.g., no invalid characters, correct formatting). This prevents potential problems that may arise during the upload process.

Step 5: Save Your Flat File

Once you’ve input all required product data and it’s been validated, save your flat file in a format supported by Amazon. FlatFilePro makes it easy to export your file as a tab-delimited text file (.txt) or an Excel workbook (.xls/.xlsx), both accepted by Amazon.

Step 6: Upload Your Flat File to Amazon

Now that you have your flat file, it’s time for the crucial step—uploading it to Amazon. Log in to your Seller Central account and follow these steps:

  1. Go to the “Inventory” tab and select “Add Products via Upload.”
  2. Choose the “Upload Your Inventory File” tab.
  3. Click “Browse” to locate your newly created flat file from FlatFilePro.
  4. Upload the file and click “Submit.”

Amazon will process the file, and you’ll receive a processing report. Review the report for any errors or issues that need to be fixed.

Step 7: Review and Monitor Your Listings

Congratulations! You’ve successfully uploaded your flat file to Amazon. It’s crucial to monitor your product listings regularly for any necessary updates or modifications. FlatFilePro’s real-time synchronization feature ensures that your listings stay up-to-date and optimized.
