Amazon Flat Files Full Guide 2023 – Filling Out Parent-Child Variations & Fixing Listing Issues

Amazon Flat File Templates Explained

Amazon flat file templates are pre-formatted spreadsheets, typically in .csv or .txt format, designed to meet Amazon’s specific product data requirements. These templates act as a guide, helping sellers create and troubleshoot their listings with precision.

Main Parts of a Flat File Template

Every Amazon flat file template is built around three key components that organize product information:

Header Row: Found at the top, this row lists the column names, each corresponding to a specific product attribute required by Amazon.
Data Rows: Each row below the header represents a single product listing, with its details aligned under the appropriate columns. This structure ensures Amazon can accurately process the data.
Type Definitions: These include drop-down lists or predefined values to maintain consistency. For instance, the "Condition Type" field must match Amazon’s accepted terms, such as "New" or "Used – Like New."

These templates also include multiple tabs to guide you through the process. Common tabs include:

Instructions: Explains how to use the file.
Data Definitions: Provides details about what information is required for each field.
Valid Values: Lists acceptable inputs for specific fields.
Template: The main tab where you input your product data.

Product Category Requirements

Amazon provides category-specific templates, tailored to meet the unique requirements of each product type and country. For example, the template for electronics will differ from the one for apparel, even though some fields may overlap.

To download the correct template, go to Seller Central, click on "Inventory", and select "Add Products via Upload." From there, choose "Download an Inventory File" and select the appropriate product category. The downloaded Excel file will be customized for your chosen category.

This category-specific approach ensures that all mandatory fields for a particular product type are included. For example, electronics listings might require technical details like wattage or compatibility, while apparel listings may need size charts or fabric descriptions.

Common Flat File Fields Explained

Despite variations between templates, certain fields are standard across most categories. Familiarizing yourself with these core fields will make navigating any template much easier:

Field	Description
SKU (Stock Keeping Unit)	A unique identifier for your product
Product ID	Typically a UPC, EAN, or ISBN
Product ID Type	Specifies the type of product ID (e.g., UPC, EAN)
Title	The product’s name or title
Price	The selling price of the product
Quantity	The number of units available in stock
Condition Type	The product’s condition (e.g., new, used)
Bullet Points	Highlights key features of the product
Product Description	A detailed overview of the product
Search Terms	Keywords that improve product discoverability
Manufacturer	The brand or maker of the product
Item Type Keyword	Helps categorize the product correctly
Image URL	Links to product images

Each field plays a crucial role in your listing’s performance. For example:

SKU helps you track inventory efficiently.
Product ID fields link your items to Amazon’s catalog.
Title and Description fields directly impact how customers find and understand your product.
Price and Quantity determine availability and cost, both critical for managing sales.
Image URL connects to your product photos, which can heavily influence purchasing decisions.

To ensure your products appear in the right categories and search results, use the Browse Tree Guide (BTG). This tool helps classify your items accurately within Amazon’s system.

Accuracy is critical when filling out these fields. Errors like missing mandatory data or incorrect formatting can lead to upload issues, while inconsistent details might confuse potential buyers. Mastering these fields is an essential step before diving into file creation and uploads.

Creating and Uploading Amazon Flat Files

Once you’ve gotten the hang of Amazon flat file templates, it’s time to prepare your product data and upload it to Seller Central. Doing this effectively means organizing your data accurately, formatting it properly, and sticking to Amazon’s specific upload guidelines.

Getting Your Data Ready

Before diving into the flat file, start by gathering all the essential details for your products. This includes SKU numbers, product titles, brand names, descriptions, prices, and inventory quantities. Having everything collected and organized beforehand will save you time and help avoid mistakes during the file creation process.

Next, download the correct category-specific template from Seller Central. Each product category has its own set of requirements, so choosing the right template is key to ensuring a smooth upload process.

When filling out the template, begin with the required fields. These typically include SKU, Product Name, Brand, Standard Description, Price, and Quantity. Missing any mandatory fields can cause errors that will stop your listings from going live. Once the essentials are complete, you can make your listings more appealing by adding optional details like Condition, Bullet Points, Search Terms, and Images.

Before saving your work, double-check everything. Make sure your pricing is formatted correctly (e.g., $19.99), your SKUs match your internal system, and your product categorization aligns with Amazon’s guidelines. Save the file as either a .txt or .csv file, as Amazon does not accept Excel formats.

Uploading Files to Amazon Seller Central

To upload your file, log in to Seller Central and head to Inventory > Add Products via Upload > Upload your Inventory File. Select your prepared file and hit Upload File.

Keep in mind that Amazon processes uploads in batches, so you might not see immediate results. To track the progress, use the Inventory File Error Report. You can generate this report by navigating to Inventory > Inventory Reports > Generate Report. It will flag issues like missing data, formatting errors, incorrect SKUs, or duplicate entries.

Carefully review the error report, fix any problems in your original file, and re-upload the corrected version. Here’s a quick summary of the key steps:

Upload Step	Action Required	Location in Seller Central
Download Template	Select the category-specific template	Inventory > Add Products via Upload > Download an inventory file
Check Data	Generate and review the error report	Inventory > Inventory Reports > Generate Report > Inventory File Error Report
Upload File	Upload the completed template	Inventory > Add Products via Upload > Upload your Inventory File

The time it takes for your file to process can range from 15 minutes to several hours, depending on the file size and Amazon’s system load. Once you’ve uploaded the file, the next step is to address any errors to ensure a seamless listing process.

Fixing Flat File Upload Errors

Flat file uploads can sometimes hit roadblocks, delaying your product listings from going live. By understanding Amazon’s error codes and learning how to fix common issues, you can save yourself a lot of time and frustration. Let’s break down the most common errors and how to address them effectively.

Amazon Error Codes Explained

Amazon assigns specific error codes to pinpoint what went wrong with your upload. Knowing these codes helps you troubleshoot quickly instead of guessing where the problem lies.

Error 8541: This code pops up when there’s a conflict in SKU data compared to what Amazon already has in its system.
Error 8542: This indicates multiple data conflicts within your file. It often happens when variations don’t align properly with existing parent-child relationships.
Error 8016: You’ll see this when there are issues with product variations, such as trying to add child products to a parent ASIN that doesn’t support them.
Error 8560: This error flags missing mandatory data for your product category. Each category has specific required fields, and leaving any of them blank will trigger this issue.
Error 5000: Formatting problems in your data cause this error. For instance, using an incorrect date format (Amazon expects MM/DD/YYYY in the US) or including special characters in product titles can lead to this.
Error 90057: This code indicates invalid values that don’t match Amazon’s accepted options, such as entering an unsupported size.
Error 99010: Missing values in required attribute groups, like dimensions (length, width, height), will trigger this error.

Solving Data Format Problems

Amazon has strict formatting rules, and even small errors can derail your upload. Here are some key guidelines to follow:

Price Formatting: For US listings, prices should be in the format $19.99 without extra currency symbols or spaces. For amounts over $1,000, skip the comma (e.g., use $1500.00 instead of $1,500.00).
Date Formatting: Always use the MM/DD/YYYY format for dates. Using formats like DD/MM/YYYY will result in validation errors.
Text Field Limits: Make sure product titles and bullet points stay within Amazon’s character limits to avoid rejections.
Special Characters: Avoid unsupported symbols in titles and descriptions. For example, replace trademark symbols with "(TM)" and skip punctuation like quotation marks or ampersands.
SKU Formatting: Stick to a consistent SKU format throughout your file to help Amazon match your products correctly.

Use Amazon’s Check My File feature to identify errors before uploading. Also, ensure you download the correct template for your product category, as requirements can vary.

Preventing Upload Mistakes

While fixing errors is important, preventing them in the first place is even better. By adopting solid data preparation practices, you can avoid most issues altogether.

Template Selection: Always download the latest template from Seller Central. Amazon regularly updates its requirements, so relying on old files can lead to errors.
Data Validation: Double-check all required fields against Amazon’s guidelines for your product category. If you sell in multiple categories, make sure you’re using the right template for each one.
File Organization: Keep your file clean by removing extra columns, empty rows, or unnecessary formatting. Save it as a .txt or .csv file, not an Excel document.
Batch Testing: Test your upload with a small batch of 10–20 products to ensure your data and formatting are accurate before scaling up.
Regular Auditing: Periodically review your data for accurate prices, descriptions, and inventory levels.
Backup Preparation: Maintain a clean backup of your file to simplify recovery if something goes wrong.

For an extra layer of protection, consider tools like FlatFilePro’s Reflection Engine. It validates your data before upload, catching errors like formatting issues or missing fields. Its real-time error checking pinpoints exactly what needs fixing, while the activity log keeps a record of changes for future reference.

Making Amazon Catalog Management Simple

Managing an Amazon catalog doesn’t have to be a headache – especially when you have the right tools.
