如何使用gspread將表格（列表清單）寫入Google電子表格

Question

我有一個表格，它以Python列表的形式列出，我想用gspread庫將其寫入一些Google Spreadsheet。但是，gspread似乎沒有這種功能。當然，我可以使用循環和更新特定的單元格，但這是非常低效的解決方案，因爲它必須執行多個請求（每個單元一個請求）。如何做得更好？

您可以使用Worksheet.range來選擇想要更新的範圍，然後將表格內容寫入此範圍並使用Worksheet.update_cells批量更新它們。

下面的代碼片段修改自this tutorial。

def numberToLetters(q): 
    """ 
    Helper function to convert number of column to its index, like 10 -> 'A' 
    """ 
    q = q - 1 
    result = '' 
    while q >= 0: 
     remain = q % 26 
     result = chr(remain+65) + result; 
     q = q//26 - 1 
    return result 

def colrow_to_A1(col, row): 
    return numberToLetters(col)+str(row) 

def update_sheet(ws, rows, left=1, top=1): 
    """ 
    updates the google spreadsheet with given table 
    - ws is gspread.models.Worksheet object 
    - rows is a table (list of lists) 
    - left is the number of the first column in the target document (beginning with 1) 
    - top is the number of first row in the target document (beginning with 1) 
    """ 

    # number of rows and columns 
    num_lines, num_columns = len(rows), len(rows[0]) 

    # selection of the range that will be updated 
    cell_list = ws.range(
     colrow_to_A1(left,top)+':'+colrow_to_A1(left+num_columns-1, top+num_lines-1) 
    ) 

    # modifying the values in the range 

    for cell in cell_list: 
     val = rows[cell.row-top][cell.col-left] 
     cell.value = val 

    # update in batch 
    ws.update_cells(cell_list) 

您可以通過以下方式來使用它：

import gspread 
from oauth2client.service_account import ServiceAccountCredentials 

# your auth here 
scope = ['https://spreadsheets.google.com/feeds'] 
credentials = ServiceAccountCredentials.from_json_keyfile_name('credentials.json', scope) 

gc = gspread.authorize(credentials) 
# your spreadsheet have to be shared with 'client_email' from credentials.json 

gc = gspread.authorize(credentials) 
# end of auth 

spreadsheet = gc.open_by_url(my_url) # url to your spreadsheet here 
ws = spreadsheet.sheet1 # or select any other sheet 

table = [['one', 'two', 'three'], [4, 5, 6]] 

# you may need to resize your worksheet so it have the neccessary cells 
# ws.resize(len(table),len(table[0])) 

update_sheet(ws, table)
