[英]how to append data using openpyxl python to excel file from a specified row?
I have different Python list variables(data1, data2, data3 ect) containing data which I want to put into an already existing excel sheet. 我有不同的Python列表变量(data1,data2,data3等),其中包含我想要放入已经存在的Excel工作表中的数据。 Presently My loop goes like this.
现在,我的循环就像这样。
for row, entry in enumerate(data1,start=1):
st.cell(row=row, column=1, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data2,start=1):
st.cell(row=row, column=2, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data3,start=1):
st.cell(row=row, column=3, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data4,start=1):
st.cell(row=row, column=4, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data5,start=1):
st.cell(row=row, column=5, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data6,start=1):
st.cell(row=row, column=6, value=entry)
work.save('sample.xlsx')
for row, entry in enumerate(data7,start=1):
st.cell(row=row, column=7, value=entry)
work.save('sample.xlsx')
Once my Python script runs, It will store the data from the 1st row. 一旦我的Python脚本运行,它将存储第一行的数据。 If I am again running the script I want the new data to come below the available data
如果我再次运行脚本,我希望新数据低于可用数据
How to do so? 怎么办?
Try using 尝试使用
sheet.max_row
it will return the last row value, You can start writing the new values from here. 它将返回最后一行值,您可以从这里开始编写新值。
max = ws.max_row
for row, entry in enumerate(data1,start=1):
st.cell(row=row+max, column=1, value=entry)
Hope it helps.Happy Coding :) 希望它有所帮助。快乐的编码:)
openpyxl has many different methods to be precise but ws.append in previous answers is strong enough to answer your demands. openpyxl有许多不同的方法可以准确,但在之前的答案中wsappend足以满足您的要求。 Consider you have written your data to a new sample.xlsx :
考虑您已将数据写入新的sample.xlsx :
from openpyxl.workbook import Workbook
headers = ['Company','Address','Tel','Web']
workbook_name = 'sample.xlsx'
wb = Workbook()
page = wb.active
page.title = 'companies'
page.append(headers) # write the headers to the first line
# Data to write:
companies = [['name1','address1','tel1','web1'], ['name2','address2','tel2','web2']]
for info in companies:
page.append(info)
wb.save(filename = workbook_name)
Now, to append new lines you must first open an existing book with load_workbook : 现在,要附加新行,您必须首先使用load_workbook打开现有书籍:
from openpyxl import load_workbook
workbook_name = 'sample.xlsx'
wb = load_workbook(workbook_name)
page = wb.active
# New data to write:
new_companies = [['name3','address3','tel3','web3'], ['name4','address4','tel4','web4']]
for info in new_companies:
page.append(info)
wb.save(filename=workbook_name)
ws.append()
将始终在任何现有数据下添加行。
You can use the append() method to append values to the existing excel files. 您可以使用append()方法将值附加到现有的excel文件。 Example:
例:
workbook_obj = openpyxl.load_workbook(excelFilePath)
sheet_obj = workbook_obj.active
col1 = 'NewValueCol1'
col2 = 'NewValueCol2'
sheet_obj.append([col1, col2])
workbook_obj.save(excelFilePath)
here the col1 and col2 values will be added with the existing data in the excel sheet. 这里col1和col2值将与excel表中的现有数据一起添加。
