How to Fix Error 90061: Invalid Column Heading in Your Upload File

Before: A seller edited a template to add a custom column “Item Title” (capital T) and inadvertently left a trailing space after “price”. The feed processed, but Amazon ignored the entire price column, resulting in listings with no price displayed.
After: The seller either removed the stray space or rebuilt the file using a newly downloaded template, ensuring the header reads exactly “price”. The subsequent upload updates all product prices correctly, and the listings appear fully populated.

Error 90061 blocks uploads when a column header (e.g., “price ” with a trailing space) doesn’t exactly match Amazon’s schema. Correct the header or rebuild the file using a fresh template, and refresh the template at least once a month to avoid repeat failures.

Overview

Amazon sellers encounter error 90061 when a column header in a flat‑file upload does not match the exact field name Amazon expects. The mismatch causes the platform to discard every value under that heading, potentially leaving listings incomplete or preventing updates. Fixing the issue quickly is essential to keep product information accurate and avoid delays in getting items live.

Key Points

Invalid heading identified — The system flags any column whose title differs even slightly from the official Amazon schema, such as an extra space or a misspelled word.
Data under the bad column is ignored — All rows in the offending column are skipped, so pricing, inventory, or description fields may never reach Amazon’s catalog.
Other columns usually process — Only the column with the incorrect header is dropped; the remainder of the file continues through the feed pipeline.
Two remediation routes — Sellers can either edit the existing file to correct the header or start with a fresh template and copy their data into it.
Strict header matching — Amazon’s parser requires an exact, case‑sensitive match; even “sku” versus “SKU” will trigger the error.
Repeated errors waste time — Large catalog owners who repeatedly submit faulty files can lose hours of work and experience inventory lag.
