Installation

Pypi:

Example

from python_calamine import CalamineWorkbook

workbook = 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.

from python_calamine import CalamineWorkbook

workbook = 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.
