Adding a sheet to an existing excel worksheet without deleting other sheet

徘徊边缘 提交于 2019-12-06 03:39:34
I am trying to add a sheet to the excel file: ex.xls and whenever I do it deletes all the previously made sheets. How do I add a sheet to this excel file without deleting the other sheets? Here is my code to create a sheet: import xlwt import xlrd wb = Workbook() Sheet1 = wb.add_sheet('Sheet1') wb.save('ex.xls') I believe this is the only way to do what you want: import xlrd, xlwt from xlutils.copy import copy as xl_copy # open existing workbook rb = xlrd.open_workbook('ex.xls', formatting_info=True) # make a copy of it wb = xl_copy(rb) # add sheet to workbook with existing sheets Sheet1 = wb

I know we can use

ValueError: row index was 65536, not allowed by .xls format

时光总嘲笑我的痴心妄想 提交于 2019-12-05 21:25:49
Currently, I am trying to edit an existing excel file using xlwt. I do not want to edit directly on the excel, so I first make a copy. new_wb = xlutils.copy(file_location) From this copy, I used the xlwt module to write a new column into the newly copied excel file and save. However, I get an error when I try to copy: ValueError: row index was 65536, not allowed by .xls format I am a little confused because the file I duplicate is a xlsx file, not xls. I never use the xls format in my code. Any guidance would be greatly appreciated. Try openpyxl instead. It support .xlsx files. The row limit

I have to create Excel spreadsheet with nice format from Python. I thought of doing it by: I start in Excel as it is very easy to format: I write in Excel the model I want, with the good format I read this from Python I create from Python an Excel spreadsheet with the same format In the end, the purpose is to create from Python Excel spreadsheets, but formatting with xlwt takes a lot of time, so I thought of formatting first in Excel to help. I have researched for easy ways to doing this but haven't found any. I can stick to my current working solution, using xlwt in Python to create formatted

xlwt - How to add page breaks to an Excel File?

自闭症网瘾萝莉.ら 提交于 2019-12-05 17:57:23
I'm trying to add page breaks whenever a column's value changes in Excel using Python and xlwt . Does anyone know how to do this? I found one example but they don't really say if their code works, and they don't say what the numbers mean in the tuple: ws.horz_page_breaks = [(54, 0, 255), (108, 0, 255)] Doing some web research I found this OpenOffice.org document describing Excel's format and BIFF records. It seems for horizontal breaks (pag. 181), each tuple represents: Index to first row BELOW the page break Index to first column of the page break Index to last column of the page break So,

Python XLWT adjusting column widths

问题 I am enormously impressed with the ease of use of XLWT, but there is one thing I have not figured out how to do. I am trying to adjust certain rows to the minimum width they would need to display all characters (in other words, what excel would do if you double clicked on the divider between cells). I know how to adjust the column widths to a predetermined amount, but I am not certain how to determine the minimum width needed to display everything. 回答1: Width is 1/256 the width of the zero

Writing xlwt dates with Excel 'date' format

落爺英雄遲暮 提交于 2019-12-05 02:35:08
I'm using xlwt to make a .xls spreadsheet, and I need to create date cells. I've got writing out numbers, and setting the number format string to make them look like dates, but critically they aren't actually getting written as dates - if you do format cell in Excel, it's a "custom" Category rather than a "date" one, and this matters. Can I make xlwt actually write "date" cells? The number will show up in the Excel "Date" category if you use a format string that corresponds to one of Excel's built-in format strings such as dd/mm/yyy . for example: import xlwt import datetime workbook = xlwt

Python Xlrd and Xlwt

I have the following content in an old Excel sheet: I need to generate a new Excel sheet with the following values: In the input Excel file's 3rd column I have a range 10010-10040 and an increment value of 10 . This needs to be expanded in my new Excel file. If I give a comma (,) in between values, it should be treated as separate values and expanded. (Like in row2, column 3) I have no idea how to do this and I am new to Python. Try the following. This uses the xlrd and xlwt libraries to read and write xls spreadsheets: import xlrd import xlwt wb_in = xlrd.open_workbook(r'input.xls') sheet
