Python binding for beautiful Rust's library for reading excel and odf file - [calamine](https://github.com/tafia/calamine).

### Is used

* [calamine](https://github.com/tafia/calamine)

* [pyo3](https://github.com/PyO3/pyo3)

* [maturin](https://github.com/PyO3/maturin)

### Installation

Pypi:

```

pip install python-calamine

```

Conda:

```

conda install -c conda-forge python-calamine

```

### Example

```python

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`.

```python

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"],

# ]

```

Also, you can use monkeypatch for pandas for use this library as engine in `read_excel()` (only pandas 2.0 and 2.1 are supported).

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

```python

from pandas import read_excel

from python_calamine.pandas import pandas_monkeypatch

pandas_monkeypatch()

read_excel("file.xlsx", engine="calamine")

#            1   2   3   4   5   6   7

# 0          1   2   3   4   5   6   7

# 1          1   2   3   4   5   6   7

```

Also, you can find additional examples in [tests](https://github.com/dimastbk/python-calamine/blob/master/tests/test_base.py).
