蟒蛇：創建Excel工作簿和傾銷CSV文件作爲工作表

Question

我有幾個CSV文件，我想在一個Excel工作簿（XLS/XLSX）轉儲作爲新的工作表。 我該如何做到這一點？

使用谷歌搜索並找到'pyXLwriter'，但似乎該項目已停止。 雖然我試着'pyXLwriter'想知道是否有任何替代品/建議/模塊？

很多謝謝。

[編輯]

這裏是我的解決方案：（任何人有更爲精簡，許多Python的解決辦法做評論THX？）

import glob 
import csv 
import xlwt 
import os 

wb = xlwt.Workbook() 


for filename in glob.glob("c:/xxx/*.csv"): 
    (f_path, f_name) = os.path.split(filename) 
    (f_short_name, f_extension) = os.path.splitext(f_name) 
    ws = wb.add_sheet(str(f_short_name)) 
    spamReader = csv.reader(open(filename, 'rb'), delimiter=',',quotechar='"') 
    row_count = 0 
    for row in spamReader: 
     for col in range(len(row)): 
      ws.write(row_count,col,row[col]) 
     row_count +=1 

wb.save("c:/xxx/compiled.xls") 

print "Done" 

Answer 1

不知道什麼你通過「更爲精簡，Python的很多」的意思，但你肯定會美化它一點：

import glob, csv, xlwt, os 
wb = xlwt.Workbook() 
for filename in glob.glob("c:/xxx/*.csv"): 
    (f_path, f_name) = os.path.split(filename) 
    (f_short_name, f_extension) = os.path.splitext(f_name) 
    ws = wb.add_sheet(f_short_name) 
    spamReader = csv.reader(open(filename, 'rb')) 
    for rowx, row in enumerate(spamReader): 
     for colx, value in enumerate(row): 
      ws.write(rowx, colx, value) 
wb.save("c:/xxx/compiled.xls")

我永遠只是通過串寫了Office 2003的XML格式。與編寫和壓縮構成xlsx文檔的內容相比，這很容易實現，而且更容易管理。它也不需要任何外部庫。 （雖然人們可以輕鬆推出自己的產品）

另外，Excel支持加載CSV文件。空格分隔或字符分隔。你可以直接加載它，或者嘗試複製&粘貼它，然後按下選項中的文本到列按鈕。當然，這個選項與python無關。

您會在此xlwt tutorial中找到所有您需要的。這個庫（xlrd and xlwt）是管理Python中Excel交互的最流行的選擇。缺點是，目前他們只支持Excel二進制格式（.xls）。

另外在GitHub庫「Kampfmitexcel」可......

import csv, xlwt, os 

def input_from_user(prompt): 
    return raw_input(prompt).strip() 

def make_an_excel_file_from_all_the_txtfiles_in_the_following_directory(directory): 
    wb = xlwt.Workbook() 
    for filename in os.listdir(data_folder_path): 
     if filename.endswith(".csv") or filename.endswith(".txt"): 
      ws = wb.add_sheet(os.path.splitext(filename)[0]) 
      with open('{}\\{}'.format(data_folder_path,filename),'rb') as csvfile: 
       reader = csv.reader(csvfile, delimiter=',') 
       for rowx, row in enumerate(reader): 
        for colx, value in enumerate(row): 
         ws.write(rowx, colx, value) 
    return wb 

if __name__ == '__main__': 
    path_to_data = input_from_user("Where is the data stored?: ") 
    xls = make_an_excel_file_from_all_the_txtfiles_in_the_following_directory(path_to_data) 
    xls_name = input_from_user('What do you want to name the excel file?: ') 
    xls.save('{}\\{}{}'.format(data_folder_path,xls_name,'.xls')) 
    print "Your file has been saved in the data folder." 

Answer 5

使用xlsxwriter創建並寫入python中的excel文件。

由安裝：安裝PIP xlsxwriter

import xlsxwriter 


# Create an new Excel file and add a worksheet. 
workbook = xlsxwriter.Workbook('demo.xlsx') 
worksheet = workbook.add_worksheet() 

# Widen the first column to make the text clearer. 
worksheet.set_column('A:A', 20) 

# Add a bold format to use to highlight cells. 
bold = workbook.add_format({'bold': True}) 

# Write some simple text. 
worksheet.write('A1', 'Hello') 

# Text with formatting. 
worksheet.write('A2', 'World', bold) 

# Write some numbers, with row/column notation. 
worksheet.write(2, 0, 123) 
worksheet.write(3, 0, 123.456) 

# Insert an image. 
worksheet.insert_image('B5', 'logo.png') 

workbook.close()

這是立足於回答你的答案本身。但是我使用xlsxwriter的原因是，它接受xlsx格式的更多數據。由於xlwt限制你以65556行和xls格式。

import xlsxwriter 
import glob 
import csv 
workbook = xlsxwriter.Workbook('compiled.xlsx') 
for filename in glob.glob("*.csv"): 
    ws = workbook.add_worksheet(str(filename.split('.')[0])) 
    spamReader = csv.reader(open(filename, 'rb'), delimiter=',',quotechar='"') 
    row_count = 0 
    print filename 
    for row in spamReader: 
     for col in range(len(row)): 
      ws.write(row_count,col,row[col]) 
     row_count +=1 

workbook.close()
