关于python:Openpyxl number_format不修改从公式派生的单元格值

Openpyxl number_format not modifying cell values derived from formula

Openpyxl的'number_format'不会修改从公式得出的单元格值,因为结果值是Python中的String类型。

对于读取轨迹信息的软件,我需要采用特定的自定义格式的数据。

注意:我已经看到了此处解决的相同问题:https://bitbucket.org/openpyxl/openpyxl/issues/376/number-format-not-refreshing-cells

I agree with the original answer: the issue is that excel is not storing the data resulting from the formulas in its cache. The data is stored as a string. I am just not sure how to change the data from String to int once it is read by Openpyxl:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20

import csv
import openpyxl
from openpyxl.styles import Alignment

wb = openpyxl.Workbook()
ws = wb.active
wb.active
f = open(r"...\\....\\...\\automated.csv")
reader = csv.reader(f, delimiter=',')

for row in reader:
    ws.append(row)
f.close()
wb.save(r"...\\...\\...\\...\\automated.xlsx")

sheet=wb.active
wb.guess_types = True
sheet['F1'] = '***** Time Start'
rowNumber = 2  # Start reading from row 3
for i, cellObj in enumerate(ws, 3):  # 3 is the starting row to write on
    rowNumber += 1
    cellObj = ws.cell(row=i, column=6)  # 6 is the column to start writing on
    cellObj.value = '=OFFSET(B6,E{0},0)'.format(str(rowNumber).format(i))
    cellObj.number_format = 'dd mmm yyyy hh:mm:ss.000"UTCG"'
    if i == 25:
        break
ws = wb.active

wb.save(r"...\\...\\...\\...\\automated.xlsx")

我知道代码正在工作,因为存储为'0'的值已被代码完美修改(请参见突出显示),因为它们不对该单元格使用任何公式:

Excel Output

注意:number_format应用于所有单元格(我检查了每一行):

result of number_format in output

但是由于单元格是字符串,所以它不能反映更改。

I am fairly new to Python and attempted to cast cellObj.value as an int but that did not work.

任何帮助或建议如何做到这一点将不胜感激。在过去的4天里,我一直在研究Stack Overflow,但没有看到解决此问题的任何方法。谢谢!

编辑:我正在使用最新版本的openpyxl 2.5.3,并尝试过此操作:
openpyxl python-将csv写入excel可以将数字设置为文本格式,但无法正常工作-我所有的值都变成了零:

Output Result Null


您将需要使用strptime方法将字符串转换为datetime对象。
