Bulk ISBN conversion requires a Basic Plan or higher.
The Basic Plan allows you to bulk convert ISBNs and EANs.
See PlansISBN 10 to 13 Bulk Converter
Enter ISBN-10, ISBN-13, EAN, ASIN, or UPC codes in any format and bulk convert them all at once.
This page bulk converts ISBN10's to ISBN13's (also known as EAN's) and vice versa.
Enter your ISBN's or EAN's in whatever bulk format you like and click the "Convert ISBN's" button. CSV, space, or tab separated is supported, only ISBN's and EAN's are converted, other text is left as it was entered.
Please be aware that some EANs (e.g., those in the 979... range) are outside the addressable range of ISBN-10 and will not be converted to ISBN-10. These EANs will be left as-is. However, you can enable ASIN conversion (requires a premium or higher plan), and we will attempt to convert these EANs to their corresponding Amazon ASIN for you as well.
