CSV upload errors

You uploaded a file with the wrong extension or content type. Save your file as .csv (not .xlsx, .numbers, or .txt) and try again.

In Excel: File → Save As → CSV UTF-8 (Comma delimited). In Google Sheets: File → Download → Comma Separated Values (.csv). In Numbers: File → Export To → CSV.

The file uploaded but no rows were usable. Common causes:

• Empty file or only a header row.
• All rows missing the required name column.
• File parsing failed silently (wrong encoding, wrong delimiter).

Open the file in a text editor or spreadsheet and confirm there are real product rows with at least a name value.

Your file has more than 50,000 rows. Split it into multiple files of up to 50,000 each, or contact support for bulk uploads if you need to process more in one job.

The required name column isn’t there. CataSEO accepts any of these as the name column (case-insensitive):

• name
• product_name
• title
• product

Add a column with one of these headers, populate it with product names, and re-upload.

The file structure couldn’t be parsed. Common causes:

• Wrong delimiter — CataSEO expects comma-separated. Semicolons (common in European locales) won’t work.
• Mismatched quotes — an unmatched " in a row breaks the rest of the file.
• Non-UTF-8 encoding — save as UTF-8 to avoid character corruption.

The error message includes details from the parser. Look at the row referenced (if any), fix the structure, and re-upload.

Warnings — the upload proceeds, but rows with warnings are skipped or partially processed. You’ll see a summary at the end.

Errors — the whole upload is rejected. You must fix the file and re-upload.
