Overview

Amazon sellers encounter error 95012 when a product feed contains characters that fall outside the plain ASCII range in fields that demand only basic text. The issue typically appears during a flat‑file upload or a bulk listing update, causing the feed to be rejected and delaying the appearance of new or revised products. Resolving the problem quickly is essential to keep inventory timelines on track.

Key Points

• Error trigger — The feed is blocked when any required column, such as SKU or a product identifier, includes characters like curly quotes, em dashes, or accented letters.
• Typical offenders — Characters such as “ ”, —, é, ñ, ™, and other Unicode symbols are the most common culprits.
• Affected fields — Amazon enforces ASCII‑only input for SKU, UPC/EAN/ISBN, and certain backend keyword columns; inserting non‑ASCII symbols in these spots triggers the error.
• Root cause — Copy‑pasting from word processors, websites, or supplier spreadsheets often introduces hidden typographic symbols that look normal but are not ASCII.
• Fix method — Identify the flagged column, replace each offending character with its ASCII counterpart, and resubmit the file.
• Prevention tip — Use plain‑text editors or validation scripts before uploading to strip out non‑ASCII characters and avoid repeat rejections.

How the Error Occurs

1. Data source copy — A seller copies a product description from Microsoft Word, where straight quotes are automatically converted to curly quotes (“example”). The hidden curly quotes are Unicode, not ASCII.
2. Feed generation — The copied text is pasted into a spreadsheet template and saved as a tab‑delimited flat file. Because the spreadsheet retains the Unicode characters, the resulting feed contains non‑ASCII symbols.
3. Amazon validation — During the upload process, Amazon’s parser checks each required column for ASCII compliance. When it finds a curly quote in the SKU column, it flags error 95012 and rejects the entire file.
