xlwings

问题 I found xlwings is a very exceptional project as a bridge between Excel and Python. So I am applying it to my excel addin development. But I got some problem. When excel addin calls python module, the Workbook.caller() does not return Workbook object(addin workbook itself)! Just Error! Instead of Workbook.caller(), I make use of 'Workbook() passing by 'Current ActiveWorkbook's name'. But in that case, I'm afraid that 'Optimize_connection= true' may raise memory garbage issue! (If 'IsAddin'

问题 I am new to Python and working on a project that I could use some help on. So I am trying to modify an existing excel workbook in order to compare stock data. Luckily, there was a program online that retrieved all the data I need and I have successful been able to pull the data and write the data into a new excel file. However, the goal is to pull the data and put it into an existing excel file. Furthermore, I need to overwrite the cell values in the existing file. I believe xlwings is able

问题 I have an Excel 2016 Book.xlsm . In the worksheet testsheet , the cells in the range A1:Y150 are filled with text or number contents. The upper-left cell is always A1 . I am using python v3 xlwings to open the Excel file. import xlwings as xw Book_name = 'C:/Users/name/Book.xlsm' sheet_name = 'testsheet' wb = xw.Book(Book_name) sht = wb.sheets[sheet_name] How do I find out the range of cells that are filled with contents using python, which in this case is A1:Y150 ? 回答1: If wb is defined as

问题 I am using xlwings to write and read data from Excel files using python 3.4 (Anaconda package). I installed xlwings with pip install xlwings Update: I realized that I might not have given enough info about what I am trying to do. So here it is: I am writing my code in the editor called Spyder. What I usually do is, I put the "import commands" at the beginning of my code. However, when I run the code, the "import command" for xlwings would not work and gives me the "ImportError" I am taking

问题 Hope you can help me out, first question I ask myself but I am always impressed by the professional answers I find here! I am using xlwings to both read and write data from .xls files. I am not a seasoned programmer, and I make mistakes. From time to time, this means rebooting processes, Python and what-not. Every now and again, I would get the following AttributeError upon calling Workbook() . The real problem is not that I don't have a clue what is happening (I tried reading the modules the

问题 When I plot a chart by xlwings, I can't change chart name. The chart name and legend name are still 'Series 1', but the upper left corner shows 'Feb sales' which is I want import xlwings as xw sht = xw.Book().sheets[0] sht.range('A1').value = list(zip([1, 2, 3, 4])) chart = sht.charts.add() chart.set_source_data(sht.range('A1').expand()) chart.chart_type = 'line_markers' chart.name='Feb sales' #chart.api.ChartTitle.Text = 'Feb sales' #chart.delete() created chart Is this a known issue? How

问题 I've mostly only used xlwings to open ( read-write ) workbooks (since the workbooks I read have complicated macros). But I've recently begun using openpyxl to open ( read-only ) workbooks when I've needed to read thousands of workbooks to scrape some data. I've noticed that there is a considerable difference between how xlwings and openpyxl read workbooks. I believe xlwings relies on pywin32 to read workbooks. When you read a workbook with xlwings.Book(<filename>) the actual workbook opens up

问题 When I use xlwings to automate stuff in excel, I still have EXCEL zoombie process running even if I quit the application (with wb.Application(wb).quit()). Thus, when I try to re open my excel file that bugs. I have to manually kill the excel application. edit : I use the xlwings 0.7.0 回答1: The issue is that wb is a global reference to your workbook which still exists even after executing the quit command. Excel sees that it is being referenced (through COM) and thus refuses to shut down

问题 I have an excel with a defined name, cell A1 has assigned name "myName" is there a way with xlwings to take its content from its name rather than on its coordinates? It should be the same of title, coord = next(wb.defined_names['myName'].destinations) content = wb[title][coord].value in openpyxls 回答1: Sure, just do: import xlwings as xw xw.sheets[0].range('myName').value See also: http://docs.xlwings.org/en/stable/api.html#name 回答2: Using xlwings, very similarly to VBA, you could use the
