使用 openpyxl 将数据从一个 excel sheet 复制到另一个列的可能性

Question

是否可以从一个 excel sheet 复制数据，即从 A、B、C 列复制数据并粘贴到另一个 sheet 的 G、H、I 列中，使用openpyxl 和 python?

Answer 1

可以，请看下面的代码：

source-data: 'Sheet1'

# Import openpyxl
# Note: openpyxl package provides both read and write capabilities to excel
import openpyxl
import string
import os


# Class definitions should use CamelCase convention based on pep-8 guidelines
class CustomOpenpyxl:

    # Initialize the class with filename as only argument
    def __init__(self, _my_file_name):
        assert _my_file_name.split('.')[-1] == 'xlsx', 'Input file is not xlsx'
        self.my_filename = _my_file_name
        self.my_base_wb = openpyxl.load_workbook(self.my_filename, read_only=False)

    # Method to get a mapping of column letters and their index values as reference
    # This works for upto 26 columns in a worksheet
    # No arguments for this method
    def get_col_idx_and_col_letter_map(self):
        _my_map = dict()
        for _idx, _val in enumerate(string.ascii_uppercase, start=1):
            _my_map[_val] = _idx
        return _my_map

    # Method to copy any column from one worksheet to another column in another worksheet of same workbook
    # Arguments to this method are: - Source worksheet name, source column letter,
    # Target worksheet name, target column letter
    def copy_src_col_paste_tgt_col_diff_sheets(self, _src_ws_name, _src_col_letter, _tgt_ws_name, _tgt_col_letter):
        # Iterate over the values of source worksheet and start the running index from 1
        # usually index start from 0, but for writing cells in excel row it cannot start from zero
        for _row_idx, _val in enumerate(self.my_base_wb[_src_ws_name].values, start=1):
            # Write the values to target worksheet and target column (LHS)
            # from values in source column of source worksheet (RHS)
            self.my_base_wb[_tgt_ws_name].cell(row=_row_idx,
                                               column=self.get_col_idx_and_col_letter_map()[_tgt_col_letter]).value = \
            self.my_base_wb[_src_ws_name].cell(row=_row_idx,
                                               column=self.get_col_idx_and_col_letter_map()[_src_col_letter]).value

    # Method to save the workbook
    # No arguments to this method
    def save_wb(self):
        return self.my_base_wb.save(self.my_filename)


# we are using the in-built os package and getcwd() method
_my_file_path = os.getcwd()
_my_file_name = 'Book1.xlsx'

# Instantiate an object using the newly created class in this code block
# So that this object gets access to all methods in the class
_my_src_obj = CustomOpenpyxl(_my_file_name)
_my_src_obj.copy_src_col_paste_tgt_col_diff_sheets('Sheet1', 'A', 'Sheet2', 'G')
_my_src_obj.save_wb()
