openpyxl python - 写csv到excel给出'数字格式为文本' [英] openpyxl python - writing csv to excel gives 'number formatted as text'

问题描述

我写了一个代码，通过openpyxl将.csv文件（包含数字）导入excel文件。它的工作原理，但是，所有的单元格都将数字写入excel文件作为文本。然后我必须手动纠正excel中的错误：格式为文本的数字（在单元格的角落显示小的绿色三角形）。

I have written a code to import a .csv file (containing numbers) into an excel file through openpyxl. It works, however, all the cells have written the numbers to the excel file as text. I then have to manually correct the error in excel: "Numbers formatted as text (displaying little green triangles in the corner of the cell).

有一种方法可以防止感谢

Is there a way to prevent this from happening? It occurs with any csv file, even if I make it with just numbers. Thanks

#!python2
# Add csv file to an xlsx

import os, csv, sys, openpyxl
from openpyxl import load_workbook
from openpyxl import Workbook
from openpyxl.cell import get_column_letter


#Open an xlsx for reading
wb = load_workbook('Test.xlsx')
ws = wb.get_sheet_by_name("RUN")

dest_filename = "Test_NEW.xlsx"
csv_filename = "csvfile.csv"

#Copy in csv
f = open(csv_filename)
reader = csv.reader(f)
for row_index, row in enumerate(reader):
    for column_index, cell in enumerate(row):
        column_letter = get_column_letter((column_index + 1))
        ws.cell('%s%s'%(column_letter, (row_index + 1))).value = cell


wb.save(filename = dest_filename)

print "new Cashflow created"

***** UPDATE * **

谢谢，这很有帮助。我的问题是，我的csv文件混合了文本和数字没有任何定义引号。所以我实现了以下，只要没有错误，从字符串更改为浮动。

Thanks, that helps. My problem was that my csv file had a mixture of text and numbers without any defining quotes. So I implemented the below to change it from a string to float as long as there isn't an error.

#Copy in csv
f = open(csv_filename,'rb')
reader = csv.reader(f)
for row_index, row in enumerate(reader):
for column_index, cell in enumerate(row):
    column_letter = get_column_letter((column_index + 1))
    s = cell
    try:
        s=float(s)
    except ValueError:
        pass

    ws.cell('%s%s'%(column_letter, (row_index + 1))).value = s

推荐答案

您需要将CSV文件中的值转换为您需要的值。 CSV文件中的所有值都是字符串。
ws.cell（'％s％s'％（column_letter，（row_index + 1）））value = int（cell）应该这样做。

You need to convert the value from the CSV file to what you need. All values in CSV files are strings. ws.cell('%s%s'%(column_letter, (row_index + 1))).value = int(cell) ought to do it.

BTW。您可能需要查看 ws.append（）方法。

BTW. you might want to look at the ws.append() method.
