How to fix it
- Open the file in your spreadsheet program and save or download it as CSV (choose "CSV UTF-8" if it is offered).
- Check that the file name ends in .csv, not .csv.xlsx or .numbers, including the path you typed under "Show advanced options".
- Upload the new .csv file on Products, Import.
Example
A file with this problem (named products.xlsx)
Name,SKU,Regular price Mug,MUG-1,12.00
What the checker says about it
- The file is called "products.xlsx". WooCommerce only accepts .csv and .txt files. On a normal upload WordPress refuses it with "Sorry, you are not allowed to upload this file type."; with a file path on the server WooCommerce says "Invalid file type. The importer supports CSV and TXT file formats." Save or download it as CSV first.
Once the listed rows are fixed, check the file again; the checker also looks for the other problems in WooCommerce's import code, so you do not trade one error for the next.
Other WooCommerce import errors
- Sorry, you are not allowed to upload this file type.
- The file is empty or using a different encoding than UTF-8, please try again with a new file.
- The uploaded file exceeds the upload_max_filesize directive in php.ini.
- A product with this SKU already exists.
- A product with this ID already exists.
- Invalid product type.
- All checks
