openpyxl

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 difference. This cell is not edited in my program (it is the same in all the invoices), however after the

openpyxl 向指定单元格添加图片并修改图片大小 以及修改单元格行高列宽 from openpyxl import Workbook,load_workbook from openpyxl.drawing.image import Image import os wb = Workbook() sheet=wb.active # 设置文字图片单元格的行高列宽 column_width=10 row_height=80 # 设置行高，该设置的行高与excel文件中设置的行高值是一样的 path=os.getcwd() # 输出当前目录 img_list=os.listdir(path) for r,file in enumerate(img_list,1): jpg=os.path.splitext(file)[1] # 分割文件，并将后缀名提取出来 if jpg=='.jpg': # 下面代码中的[]括号中可以输入'D'或者'd' sheet.column_dimensions['D'].width=column_width # 修改列D的列宽 sheet.row_dimensions[r].height=row_height # 修改行3的行高 img=Image(file) # 调用图像函数 newSize=(90,90) img.width,img.height

由于excel版本不同，python处理的时候选择的库页不同。 一、操作对应版本表格需要用到的库 1、操作xls格式的表格文件，需要用到的库如下： 读取：xlrd 写入：xlwt 修改（追加写入）：xlutils 2、操作xlsx格式的表格文件，需要用到的库如下： 读取/写入：openpyxl （好像对于xlsx格式的表格，使用xlrd也是可以读取的，只是写入会有问题，不过避免问题还是根据不同格式的表格选择对应的库吧~） 二、实现代码 1、xlwt写入xls文件内容 import xlwt def write_excel_xls(path, sheet_name, value): index = len(value) # 获取需要写入数据的行数(value是个二维数组) workbook = xlwt.Workbook() # 新建一个工作簿 sheet = workbook.add_sheet(sheet_name) # 在工作簿中新建一个表格 for i in range(0, index): for j in range(0, len(value[i])): sheet.write(i, j, value[i][j]) # 像表格中写入数据（对应的行和列） workbook.save(path) # 保存工作簿 print("xls格式表格写入数据成功！") #

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:"ReadOnlyWorkbookException: Cannot create new sheet in a read-only workbook") df=DataFrame() from openpyxl.reader.excel

I use openpyxl to open a file, edit some cells and save the changes. Here's an example: import openpyxl book = openpyxl.load_workbook(sheet_path) sheet = book.active for row in range(sheet.max_row): index = row + 1 sheet.cell(row=index, column=1).value = "something" book.save(sheet_path) The problem is, when I save the file, other cells are modified. In fact, the cells in my sheet that contains formulas are "corrupted", the file size is greatly reduced and when I use other scripts to read the sheet, the cells containing formulas are reported as empty. But when I open the sheet, everything

I am trying to style specific rows and columns. worksheet.cell(row=file_row_number, column=1).value = "Hotel ID" _cell = worksheet.cell("C1") _cell.style.font.bold = True It shows me error TypeError: cannot set bold attribute Previously I was using XLWT and it had very easy method of applying styles like you define style variable once and then for ever write() yo can just pass the style variable to apply style on that row/column Is there any way in OpenPyXL to apply style easily as I mentioned above? As explained here , you should first create a Style object: from openpyxl.styles import Style,

In openpyxl, you can set a hyperlink like this: cell.hyperlink = r'..\somedir\somefile.txt' However, this does not apply the hyperlink style that you would get when setting a hyperlink in Excel. You can apply a style with blue text and underlining, but when you open the document, visited hyperlinks do not change color. Is there any way with openpyxl to specify a hyperlink style that works like a hyperlink set within Excel? You have to change style attribute cell.style = "Hyperlink" import openpyxl from openpyxl.styles import Font, Color, colors #... # alternative 1: set hyperlink property to
