openpyxl

I just created a script with openpyxl to update a xlsx file that we usually update manually every month. It work fine, but the new file lost all the graphs and images that were in the workbook. Is there a way to keep them? openpyxl version 2.5 will preserve charts in existing files. Rishil Antony Use xlwings instead, it works as a wrapper on pywin32 and can preserve the existing Excel graphs, pivot-tables, etc. 来源： https://stackoverflow.com/questions/37214983/openpyxl-updating-sheet-and-maintaining-graphs-and-images

Using the python library openpyxl I am reading an XLSX file created in excel 2007. it is empty apart from cell A1 which is coloured yellow and has the value "test" written in it. I can easily retrieve the value from that cell, however when I attempt to determine the fill colour I get the following results: this_sheet.cell("A1").style.fill.start_color returns "FFFFFF" this_sheet.cell("A1").style.fill.end_color returns "FF0000" Testing this on other blank cells I get exactly the same results, and trying to retrieve the font style information keeps returning calibri size 11 (our system default).

I have an application where I write to a worksheet to the last column + 2 if there is already data and to the last column + 1 if the worksheet is empty. I get what I think is an empty worksheet as follows: from openpyxl.workbook.workbook import Workbook book = Workbook() sheet = book.active When I do sheet.max_row and sheet.max_column , I get 1 for both properties. I would like to get zero, so I do the following: if sheet.max_row == 1 and sheet.max_column == 1 and not sheet['A1'].value: start_col = 1 else: start_col = sheet.max_column + 2 Having to check the value of the cell seems a bit

I've been assigned a "simple" task of collecting series of data columns to a results workbook. The results workbook contains necessary formulas and charts to analyze the results. The data is generated by an image analysis application I've written in python as series of excel workbooks. Now the problem is that openpyxl drops any existing charts in excel workbooks. I've spent the day figuring out how to use openpyxl charts for which there is some documentation and chart errorbars for which there are no examples whatsoever. There is the source which has terse comments.. Using win32com extension

Why does x = "None" instead of "500"? I have tried everything that I know and searched 1 hour for answer... Thank you for any help! import openpyxl wb = openpyxl.Workbook() sheet = wb.active sheet["A1"] = 200 sheet["A2"] = 300 sheet["A3"] = "=SUM(A1+A2)" wb.save("writeFormula.xlsx") wbFormulas = openpyxl.load_workbook("writeFormula.xlsx") sheet = wbFormulas.active print(sheet["A3"].value) wbDataOnly = openpyxl.load_workbook("writeFormula.xlsx", data_only=True) sheet = wbDataOnly.active x = (sheet["A3"].value) print(x) # None? Should print 500? From the documentation openpyxl never evaluates
