Common issues when uploading CSV files and how to fix them.
File Not Recognized
Make sure your file has a .csv extension. Excel files (.xlsx) need to be saved as CSV first. In Excel, go to File, Save As, and select CSV as the format.
Column Mapping Failed
Valuna tries to automatically match your columns to product fields. If mapping fails:
Check that your CSV has a header row
Use clear column names like "Product Name" or "SKU"
Manually map columns in the import wizard if auto-detection fails
Special Characters Breaking
If product names or descriptions contain special characters that look wrong after import:
Save your CSV with UTF-8 encoding
In Excel: Save As, CSV UTF-8
In Google Sheets: Download as CSV (automatically UTF-8)
Empty Products After Import
If products appear but have no data:
Check that data starts on row 2 (row 1 should be headers)
Make sure there are no merged cells
Remove any blank rows in the middle of your data
Maximum File Size
CSV files up to 50MB are supported. For larger files, split them into multiple uploads.
