将复制的数据保存到不同的 excel 个文件

Question

我试图将复制数据的不同部分从一个 excel 文件保存到相应的新 excel 文件，但我将所有内容都放在一个新文件中。

我做错了什么？

例如，在图片中我想有 4 个新的 excel 文件，名称为 AAA、BBB、CCC 和 DDD。分隔是每次出现空白行时。要复制的数据将从该行开始直到下一个空白行。（所有列）

谢谢

wb1 = xl.load_workbook(xref_file)
ws1 = wb1.worksheets[0]
mr = ws1.max_row
mc = ws1.max_column

for row in range(1,ws1.max_row):
    if(ws1.cell(row,1).value is None):   
        
        wb2 = openpyxl.Workbook() 
        ws2 = wb2.active
     
        conveyor_name = ws1["A1"].value
        conveyor_name.split(' -')
        conveyor_name = conveyor_name.split(' -')[0]
        filename = conveyor_name + ".xlsx"
        destination_file = os.path.join(destination,filename)
        wb2.save(destination_file) 
    
        # copying the cell values from source 
        # excel file to destination excel file
        for i in range (1, mr+1):
            for j in range (1, mc+1):
                # reading cell value from source excel file
                c = ws1.cell(row = i, column = j)
            
                # writing the read value to destination excel file
                ws2.cell(row = i, column = j).value = c.value

        wb2.save(destination_file)  

ws1.delete_rows(1,mr)
    
wb1.save(xref_file)

编辑 1：我对您的代码所做的更改是我有额外的条件来检查是否存在空行，如果它是空行，那么它会将 new_sheet 变量设置为 true。如果它不为空且 new_sheet 为真，则创建一个新的 sheet，否则将开始一个循环，将内容复制到新的 sheet。因此更新后的代码应该如下：

wb1 = openpyxl.load_workbook(destination + "/" + xref_file)
ws1 = wb1.worksheets[0]
mr = ws1.max_row
mc = ws1.max_column

new_sheet = True
# for row in range(1,ws1.max_row):
row = 1
while row < ws1.max_row:
    if(ws1.cell(row,1).value is not None):  
        if new_sheet == True:
            wb2 = openpyxl.Workbook() 
            ws2 = wb2.active
            conveyor_name = ws1["A" + str(row)].value
            conveyor_name = conveyor_name.split()[0]
            filename = conveyor_name + ".xlsx"
            destination_file = os.path.join(destination,filename)
            print(destination_file)
            wb2.save(destination_file) 
            new_sheet = False
            row = row + 1
        else:
            # copying the cell values from source 
            # excel file to destination excel file
            for i in range (row, mr+1):
                if ws1.cell(i,1).value is None:
                    break
                for j in range (1, mc+1):
                    # reading cell value from source excel file
                    c = ws1.cell(row = i, column = j)
                
                    # writing the read value to destination excel file
                    ws2.cell(row = i - row + 1, column = j).value = c.value
            row = i
            wb2.save(destination_file)
    else:
        new_sheet = True
        row = row + 1

编辑 0：可以观察到一些优化和错误。由于我不知道 excel sheet 中数据的性质，因此其中一些可能不适用于您

wb1 = xl.load_workbook(xref_file) ws1 = wb1.worksheets[0] 
mr = ws1.max_row 
mc = ws1.max_column
for row in range(1,ws1.max_row):
    if(ws1.cell(row,1).value is None):
        wb2 = openpyxl.Workbook() 
        ws2 = wb2.active

如果上述 If 条件为真，则 A1 中不应有任何值。此外，如果 A1 中应该有一个值，那么您可能需要检查第二行中的值以通过 if 条件，因此该行的值应该从 2 到 ws1.max_row

        conveyor_name = ws1["A1"].value

下面这行没有多大意义，因为您在之后的行中再次使用了相同的值

        conveyor_name.split(' -') # this is not required
        conveyor_name = conveyor_name.split(' -')[0]
        filename = conveyor_name + ".xlsx"
        destination_file = os.path.join(destination,filename)
        wb2.save(destination_file) 

# copying the cell values from source 

# excel file to destination excel file
for i in range (1, mr+1):
    for j in range (1, mc+1):
        # reading cell value from source excel file
        c = ws1.cell(row = i, column = j)
    
        # writing the read value to destination excel file
        ws2.cell(row = i, column = j).value = c.value

wb2.save(destination_file)  

ws1.delete_rows(1,mr) wb1.save(xref_file)
