Finding Errors in Flat Files

Reading Amazon Error Reports

You can spot flat file errors by checking Amazon’s detailed error reports. These reports are automatically created after every flat file upload and provide insights into what’s causing issues with your listings.

Here’s how to access them:

1. Go to Seller Central Reports

Head to the Inventory Reports section in Seller Central to find your flat file upload error reports.

2. Download the Error Report

The report will include:

The row and column where the error occurred
The specific SKU affected
A description of the error
The expected format or value

FlatFilePro’s automated validation system can help catch many of these issues before they appear in your Amazon listings. Once you have the report, focus on the error codes to quickly pinpoint and resolve the problems.

Error Code Guide

Decoding Amazon’s error codes is crucial for resolving issues efficiently. Here’s a quick guide to some of the most common ones:

Error Code	Description	Common Solution
8541	Invalid product identifier	Check the format of UPC/EAN/ISBN
90201	Missing required field	Ensure all mandatory fields are filled
99001	Incorrect variation theme	Correct the variation relationship
20059	Invalid price format	Use the proper decimal format
8058	Duplicate SKU	Remove or update duplicate entries

FlatFilePro simplifies error management by interpreting these codes and offering actionable fixes. Its version control feature also lets you track changes and roll back if needed.

When reviewing error reports, focus on these key areas:

Pattern recognition: Repeated errors across listings often point to a larger issue.
Priority levels: Address errors that impact listing visibility or sales first.
Batch processing: Group similar errors to fix them more efficiently.
Change tracking: Keep a record of all updates to avoid repeating mistakes.

Step-by-Step Error Correction Guide

Fixing Wrong Values and Formats

Fixing errors in flat file values requires a clear, structured approach. Here’s how to handle common formatting problems:

Price Format Corrections: Always use decimal points for prices (e.g., $24.99 instead of $24,99). For bulk updates, format prices to two decimals in Excel to avoid errors.

Product Identifier Fixes: Ensure each UPC/EAN is accurate by following these steps:

Check Digit Validation
Use Excel’s LEN function to confirm the correct code length:
- UPC-A: 12 digits
- EAN-13: 13 digits
Format Verification
Remove special characters and spaces to keep data clean.
Batch Verification
Standardize data by:
- Removing leading zeros
- Normalizing number formats
- Eliminating hidden characters

Fixing these value and format issues sets the stage for addressing missing data.

Filling in Missing Data

Once formatting issues are resolved, focus on completing missing fields. Incomplete data can hurt your listings’ performance.

Required Field Completion: Pay attention to these key elements:

Field Type	Required Format	Common Mistakes to Avoid
Product Title	200 characters max	Using special characters or ALL CAPS
Description	HTML supported	Skipping bullet points
Dimensions	Numbers only	Mixing measurement units
Weight	Decimal format	Incorrect unit conversions

Time-Saving Solutions: Use FlatFilePro’s version control feature to retrieve missing data from previous versions of your listings.

Data Validation Checklist:

Use Excel’s built-in validation tools
Search for blank required fields
Confirm consistent measurement units
Check category-specific attributes for accuracy

FlatFilePro’s access control tools also help maintain data accuracy by restricting who can make changes to your listings. Following this process ensures a smoother bulk editing experience and better catalog management.
