Tool converts ISBNs from 10-digit format to 13 digits

SkuFlow launched a tool enabling booksellers to convert their 10-digit ISBNs to the 13-digit format. The switch will occur in 2007, when book publishers will begin using 13-digit ISBNs instead of the 10-digit system in use since the 1970s. Booksellers may need to convert ISBNs of their existing books to 13 digits in certain cases.

The tool converts up to 12,000 ISBNs to the new ISBN-13 (EAN) format at once.

The program is Honor Ware, which means that the program is open to the public for use and users are asked to pay a $14.99 conversion fee. You can copy and paste your ISBNs and select either .txt, .csv, or .xls output. The tool provides alerts for bad ISBNs.
