If you're getting an error while uploading a CSV file to the "Import ASIN Data" section, it’s likely because one or more fields in your file contains an unsupported character. Only commas (,) are now flagged as they are the only characters which are unsupported in our upload files.
Examples of supported characters:
For fields like category, product_group, and custom_labels, all the following characters are allowed:
Alphanumeric characters (A–Z, a–z, 0–9)
Spaces
Semicolon (;)
Ampersand (&)
Comma (,)
Slash (/)
Hyphen (-)
Accented characters (ä, ü, ö, etc.)
Common causes of errors:
Some characters that often cause issues include:
Commas (,) used instead of semicolons (;) as separators
Mistakenly changing the title of the columns from the default values.
How to fix it:
You can clean up your data using any spreadsheet tool like Google Sheets or Excel. Some of the steps you can take are:
Replace invalid characters (“,”) with valid alternatives (or remove them).
Re-download the Sample CSV available on our platform and simply replace your data without changing any titles in the first column.
Make sure there is no randomly filled cells outside the cells in which our actual data is present.
