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.

Bug#1053672: Apple copyright notices in test .xlsx files
Source: openpyxl Version: 3.0.9-2 Severity: serious licensecheck -r --copyright . on openpyxl finds these: ./openpyxl/formatting/tests/data/conditional-formatting.xlsx: UNKNOWN [Copyright: 2007 Apple Inc.] ./openpyxl/reader/tests/data/complex-styles.xlsx: UNKNOWN [Copyright: 2007 Apple Inc.] If opened in 'less' these files do contain the text "Copyright 2007 Apple Inc., all rights reserved.", marked as 'etext'. However, if opened in LibreOffice, no _obvious_ command displays this text. File > Properties instead displays creation and modification dates/authors that match the openpyxl upstream commit dates/authors (2012-4), which suggests that these are *not* straightforward copies of Apple-owned example files. Their actual contents are mostly formatting, i.e. they look like something created specifically to be a test case for reading formatting, or possibly a documentation example for formatting but the above makes that less likely, not something copied from real-world use. Given this, why is that copyright notice there, and what does it imply that we should do? (E.g. does Apple Numbers automatically copy Apple-owned items (e.g. fonts) into files it creates? If so, is there a way to remove these items to get a Free file?)
