[英]Writing dataframe to excel sheet with openpyxl
我正在嘗試將必須具有的數據框寫入Excel工作表。 這是我以幾種方式做了很多次的事情,現在我無法弄清楚我的錯誤在哪里。

我的代碼:
#initialize stuff
book = load_workbook(os.path.commonpath(output))
writer = pd.ExcelWriter(os.path.commonpath(output), engine = 'openpyxl')
writer.book = book
#Check for sheet in my excel book, if not there create it
if not 'CHECK' in book.sheetnames:
book.create_sheet('CHECK')
#Remove default excel sheets if present, and save changes to sheet
try:
book.remove_sheet(book['Sheet1'])
except:
pass
book.save(os.path.commonpath(output))
#THIS LINE WAS MISSING, CAUSING THE ERROR!
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
#write it all out at the first blank row in the excel sheet
df.to_excel(writer, sheet_name = 'CHECK', startrow = writer.sheets['CHECK'].max_row, index=False)
無論出於何種原因,我都會收到以下錯誤: KeyError: 'CHECK'
我一直在為此抓狂,因為我之前幾乎使用了這段確切的代碼,而且效果很好。
你應該改變
df.to_excel(writer,sheet_name ='CHECK',startrow = writer.sheets ['CHECK']。max_row,index = False)
至:
df.to_excel(output, sheet_name = 'CHECK', startrow = book['CHECK'].max_row, index=False)
就在df.to_excel(output, sheet_name = 'CHECK', startrow = book['CHECK'].max_row, index=False)
,我的末端缺少關鍵行!
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
^是所遺失的肇事者,原始問題將被更新。
