Here you can find downloadable copies of the data in the UPC Database. Each full download contains a file of Manufacturers by manufacturer code, and a file of items by UPC. The files are ASCII text, comma-separated values (CSV), without column headings. Text fields are quoted as necessary. These files should easily be readable by MS Access (if that's your thing), or Text::CSV (if Perl's your thing). The item file will NOT be readable in full by Excel because of Excel's limit of 65,535 data rows. The CSV files are bundled together with tar and compressed with gzip. If you still don't know what any of this means, then there is useful information for you here:

• GNU Tar for Windows
• GNU Zip

The incremental downloads are in diff(1) format. The filenames specify the two dates compared to create the diff. If you have an older full download, you can save download time by downloading and applying the diffs (with patch(1)) rather than downloading the entire database. The diff files are compress with gzip(1).
