Your import stops and displays this error:
There are two possible reasons.
Please note that MS Excel has the unpleasant habit of converting the number format. You will therefore need to ensure that the EAN13 column uses the format 'number' with no decimals.
You need to download the corresponding TODO file to verify and modify the name of the concerned product.
Save the changes, reload the TODO file and start the import process again.
You will therefore need to check and fix this before running the import again.
