將一個巨大的excel文件分割成多個文件

Question

我有一個非常巨大的excel文件。在幾行之間有「------------」這個字符串。我想將文件從「------------」分割爲另一個「------------」，並將它們命名爲「 - 」 ----------「的下一個單元格。請幫助我做到這一點。

Answer 1

我會做的是使用類似於：http://www.python-excel.org/。

pip install xlrd xlwt 

xlrd - 讀取Excel文件

xlwt - 寫入Excel文件

話，我會嘗試這樣的事：

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)) 

未經檢驗。對於xlrd和xlwt，文檔看起來非常糟糕。
