Fix Shopify CSV invalid tags format issues
Tag formatting inconsistencies can cause import warnings, broken filtering, or unexpected catalog tagging behavior.
Why Shopify throws this error
Tags are parsed using delimiter patterns. Invalid separators and noisy spacing can produce malformed tag sets.
Common causes
- - Semicolons or mixed delimiters used instead of consistent commas.
- - Repeated tags with casing differences.
- - Tags copied with hidden line breaks.
- - Very long tag strings exceeding practical maintenance limits.
