*.xlsx files are actually just *.zip files containing XML and other files. The Apple copyright for both of the files you mention comes from the Apple copyright listed for the ICC profile embedded in the EXIF data in the JPEG file that was saved as a thumbnail of the spreadsheet. I am not sure what that means for the license of the test cases in openpyxl and but it would be easy to fix by either deleting the thumbnail, or removing the ICC profile, but that would alter the test cases, probably that wouldn't affect the tests passing/failing though. $ unzip conditional-formatting.xlsx Archive: conditional-formatting.xlsx inflating: [Content_Types].xml inflating: _rels/.rels inflating: xl/_rels/workbook.xml.rels inflating: xl/workbook.xml extracting: docProps/thumbnail.jpeg inflating: xl/theme/theme1.xml inflating: xl/styles.xml inflating: xl/worksheets/sheet1.xml inflating: docProps/core.xml inflating: docProps/app.xml $ grep -ri apple grep: conditional-formatting.xlsx: binary file matches grep: docProps/thumbnail.jpeg: binary file matches $ exiftool docProps/thumbnail.jpeg | grep -i apple Profile CMM Type : Apple Computer Inc.
