Overview

Amazon sellers frequently encounter error 6000 when uploading product feeds. The error signals that a field requiring a decimal value contains characters Amazon cannot interpret, most often a comma used as a decimal separator. Fixing the formatting issue quickly prevents delays in listing new items or updating existing inventory.

Key Points

• Error trigger — Amazon flags a row when a numeric field such as price, weight, or dimension includes a non‑standard character, for example “12,99” instead of “12.99”.
• Primary cause — Replacing the period with a comma as the decimal point generates the error; a single misplaced comma can reject an entire batch file.
• Regional influence — Sellers accustomed to European, Latin American, or other locales that default to commas for decimals are especially vulnerable.
• Straightforward remedy — Swapping every comma inside a numeric value with a period resolves the issue without altering the underlying data.
• Preventive tip — Configuring spreadsheet software to use U.S. English number formatting eliminates the root cause before the file is created.
• Impact scope — Large uploads magnify the problem because one formatting mistake can cause dozens or hundreds of rows to be rejected.

How Error 6000 Occurs

1. File submission — The seller uploads a flat file (CSV, TXT, or Excel) through Seller Central’s inventory feed interface. For instance, a CSV containing 5,000 SKUs is selected for bulk price updates.
2. Field parsing — Amazon’s ingestion engine reads each column according to its defined data type. When it reaches the “price” column, it expects a string that matches the pattern digits.digits.
3. Invalid character detection — If the engine encounters a comma inside the numeric string, such as “19,95”, it cannot convert the value to a decimal and marks the row with error 6000. The same logic applies to weight (“0,75”) and dimension fields (“10,5”).
4. — Amazon aggregates all rows that failed the decimal validation and returns a feed processing report listing each offending SKU with the message “Error 6000: Invalid decimal characters”.
