将一个巨大的Excel文件拆分成多个文件

Question

我有一个非常庞大的excel文件。那里＆＃34; ------------＆＃34;几行之间的这个字符串。我想将文件从＆＃34; ------------＆＃34;中删除。到另一个＆＃34; ------------＆＃34;并用＆＃34; ------------＆＃34;＆＃39;＆＃39;＆＃39;的下一个单元格中的单词命名。请帮我这样做。

Answer 1

我要做的是使用：http://www.python-excel.org/。

pip install xlrd xlwt

xlrd - 读取Excel文件

xlwt - 写入Excel文件

然后我会尝试这样的事情：

import xlrd
import xlwt

def write_rows(batch, filename):
    current_batch_xls = xlwt.Workbook(encoding='utf-8')
    first_sheet = current_batch_xls.add_sheet(filename + ' sheet')
    for row_number, row in enumerate(batch):
        for cell_number, cell in enumerate(row):
            first_sheet.write(row_number, cell_number, cell.value, style=cell.xf_index)
    current_batch_xls.save(filename)

FILENAME='big-excel-spreadsheet.xls'
DELIMITER='------------'
big_spreadsheet = xlrd.open_workbook(FILENAME)
# assuming you have only one sheet
sheet = big_spreadsheet.sheet_by_index(0)
current_batch_of_rows = []
for row in xrange(2, sheet.nrows):
    if row.cell(row, 0) == DELIMITER:
        write_rows(current_batch_of_rows, filename=row.cell(row, 1))
        current_batch_of_rows = []
        continue
    current_batch_of_rows.append(sheet.row(row))

未测试。对于xlrd和xlwt，文档似乎非常糟糕。
