Example

frompython_calamineimportCalamineWorkbookworkbook=CalamineWorkbook.from_path("file.xlsx")
workbook.sheet_names# ["Sheet1", "Sheet2"]workbook.get_sheet_by_name("Sheet1").to_python()
# [# ["1", "2", "3", "4", "5", "6", "7"],# ["1", "2", "3", "4", "5", "6", "7"],# ["1", "2", "3", "4", "5", "6", "7"],# ]

By default, calamine skips empty rows/cols before data. For suppress this behaviour, set skip_empty_area to False.

frompython_calamineimportCalamineWorkbookworkbook=CalamineWorkbook.from_path("file.xlsx").get_sheet_by_name("Sheet1").to_python(skip_empty_area=False)
# [# [", ", ", ", ", ", "],# ["1", "2", "3", "4", "5", "6", "7"],# ["1", "2", "3", "4", "5", "6", "7"],# ["1", "2", "3", "4", "5", "6", "7"],# ]

Pandas 2.2 and above have built-in support of python-calamine.

Also, you can find additional examples in tests.
