What to check
- Use Brand/Code columns in UTF-8 CSV; commas, semicolons and quoted values are accepted.
- Keep leading zeros; identical numbers from different brands do not necessarily mean the same thread.
- Review owned colors; the list shows missing colors, not remaining length or skein quantities.
Limit: 1 MiB/5,000 rows. Invalid inventory clears the previous result; review the latest file before downloading.
