我正在尝试替换xlsx工作表中的子字符串值。

尝试了示例代码段：

for row in range(1,sheet.max_row+1):
    for col in range(1, sheet.max_column+1):
        temp = None
        cell_obj = sheet.cell(row=row,column=col)
        temp = re.search(r"requestor", str(cell_obj.value))
        if temp:
            if 'requestor' in cell_obj.value:
                cell_obj.value.replace('requestor',
                                       'ABC')

[尝试从包含值“ Customer name：requestor”的xlsx单元中替换为值“ Customer name：ABC”。如何轻松实现这一点？

Answer 1

只需保持简单即可。搜索给定值并覆盖单元格，而不是重新替换。

下面的示例还使您能够根据需要更改'客户名称'：

wb = openpyxl.load_workbook("example.xlsx")
sheet = wb["Sheet1"]

customer_name = "requestor"
replace_with = "ABC"

search_string = f"Customer name: {customer_name}"
replace_string = f"Customer name: {replace_with}"

for row in range(1, sheet.max_row + 1):
    for col in range(1, sheet.max_column + 1):
        cell_obj = sheet.cell(row=row, column=col)
        if cell_obj.value == search_string:
            cell_obj.value = replace_string

wb.save("example_copy.xlsx")  # remember that you need to save the results to the file

我在这篇文章中找到了答案：https://www.edureka.co/community/42935/python-string-replace-not-working

replace函数不会将结果存储在同一变量中。因此，上述解决方案：

mvar = None
for row in range(1,sheet.max_row+1):
    for col in range(1, sheet.max_column+1):
        temp = None
        cell_obj = sheet.cell(row=row,column=col)
        temp = re.search(r"requestor", str(cell_obj.value))
        if temp:
            if 'requestor' in cell_obj.value:
                mvar = cell_obj.value.replace('requestor',
                                       'ABC')
                cell_obj.value = mvar
