How to Watch Excel File Change While openpyxl Makes Changes

问题 I built an iOS app that takes users' inputs then uploads their data as .csv files onto dropbox. Now, I'd like to build a cross-platform desktop app that uses openpyxl and the Python dropbox api to listen for these .csv uploads and then write the data in these .csv files to various .xlsx workbooks. I have no issues with this, except my client wants to be able to watch on their desktop as the excel workbooks change. Whenever I make an assignment with openpyxl, such as... wb = load_workbook(

Openpyxl: 'Worksheet' object has no attribute 'values'

问题 My goal is to read in an excel file and view the codes in a pandas dataframe (i.e. '= A3') rather than the resulting values from excel executing the codes, which is the pandas default if read in using pandas. My goal was described here: How can I see the formulas of an excel spreadsheet in pandas / python? Openpyxl is supposed to support this, but I can't get the import to function correctly. Anyone spot the error? import pandas as pd from openpyxl import load_workbook from openpyxl.utils

问题 I've installed openpyxl from the Terminal using pip3 install openpyxl without any problems. I've even double-checked by simply running import openpyxl from the Terminal window once Python is running, and it imports no problem. The problem starts when I try and import openpyxl from a script I'm building to work with a spreadsheet. I'm using Sublime Text and can't even get past the import openpyxl at the beginning of the script without running into the following error: Traceback (most recent

问题 import openpyxl wb = openpyxl.load_workbook('D:\excel.xlsx') wb.get_sheet_names() After this, i can see the worksheets(85) that the excel file has. Now i want to go into each sheet, edit data in 2-3 cells (which is same for all the sheets) and then save the file. I am very new to python and i need help. Thanks 回答1: In your case I see the easiest is probably import openpyxl n = 0 wb = openpyxl.load_workbook('D:\excel.xlsx') sheets = wb.sheetnames ws = wb[sheets[n]] Where n is the sheetnumber

Formatting chart data labels in openpyxl

问题 I'm using Python 3.6.3 to write some excel sheets with openpyxl (2.4.9). Getting data labels on charted data wasn't obvious, but things start to go badly when I try to format said data labels. What I want to be able to do is change their position and also change their rotation. Anyone any ideas? I'm a bit fresh to python, so any advice would be great. Here's what I've tried: from openpyxl.chart import LineChart, Reference, Series from openpyxl.chart.label import DataLabelList from openpyxl

In openpyxl, how to move or copy a cell range with formatting, merged cells, formulas and hyperlinks

问题 I am trying to move a cell range inside a worksheet using Python 2.7 + openpyxl. What seemed to be an easy and basic task turned out to be close to impossible. Here is how I'd like it to look in Excel: To make the task easier let's assume I only need to move range from given cell to the end of data (to last row and column). My first idea was easy: for i, column in enumerate(columns): if i >= starting_col: for j, cell in enumerate(column): if j >= starting_row: copy_cell(ws, j+1, i+1, j+1, i

一 . Python操作EXCEL库的简介 1.1 Python官方库操作excel Python官方库一般使用xlrd库来读取Excel文件，使用xlwt库来生成Excel文件，使用xlutils库复制和修改Excel文件，这三个库只支持到Excel2003。 1.2 第三方库openpyxl介绍 第三方库openpyxl（可读写excel表），专门处理Excel2007及以上版本产生的xlsx文件，xls和xlsx之间转换容易。 注意：如果文字编码是“gb2312” 读取后就会显示乱码，请先转成Unicode 本文将详细介绍第三方库openpyxl的基本用法 第三方库openpyxl的安装： <1>下载路径：https://pypi.python.org/pypi/openpyxl <2>解压到指定文件目录：tar -xzvf openpyxl.tar.gz <3>进入目录，找到setup.py文件，执行命令：python3 setup.py install 如果报错No module named setuptools 就使用命令“easy_install openpyxl”，easy_install for win32，会自动安装setuptools； 或者直接用cmd命令：pip3 install openpyxl安装 二. openpyxl库基本操作总结 2.1

问题 I wrote a Python program which produces invoices in a specific form as .xlsx files using openpyxl. I have the general invoice form as an Excel workbook and my program copies this form and fills up the details about the specific client (eg. client refernce number, price, etc.) which are read from another .txt file. The program works perfectly. The only problem is that the form contains a cell which has multiple styles: half of the letters are red and the rest black and there is also size

问题 I have a simple use case for df.to_excel() that I'm struggling with. I want to write to a specific worksheet tab (let's call it "Data") of an existing XLSX workbook, which could be referenced by formulas and pivots on other tabs. I've tried to modify ExcelWriter in two ways but both produce errors from openpyxl. Read an existing sheet using get_sheet_by_name (This errors: "NotImplementedError: use 'iter_rows()' instead".) Create a new sheet using create_sheet. (This errors:

问题 Say I have an xlsx-file and this Excel file has cells A2 and B2 merged. I also select that merged cell and put a border at the top and bottom of the merged cell. When I do the following: wb = openpyxl.load_workbook("file.xlsx") wb.save("resulting file.xlsx") The result is that only the portion around the merged cell that is in column A now has the border: Is there a way to prevent this from happening? 回答1: I believe you are facing Issue#365 , there is generally an issue around styling for
