xlsxwriter

I can pass a StringIO object to pd.to_csv() just fine: io = StringIO.StringIO() pd.DataFrame().to_csv(io) But when using the excel writer, I am having a lot more trouble. io = StringIO.StringIO() writer = pd.ExcelWriter(io) pd.DataFrame().to_excel(writer,"sheet name") writer.save() Returns an AttributeError: StringIO instance has no attribute 'rfind' I'm trying to create an ExcelWriter object without calling pd.ExcelWriter() but am having some trouble. This is what I've tried so far: from xlsxwriter.workbook import Workbook writer = Workbook(io) pd.DataFrame().to_excel(writer,"sheet name")

I'm able to open my pre-existing workbook, but I don't see any way to open pre-existing worksheets within that workbook. Is there any way to do this? You cannot append to an existing xlsx file with xlsxwriter . There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close() which will then write all of the information to your xlsx file. Similarly, you can use a method of your own

XlsxWriter object save as http response to create download in Django? I think you're asking about how to create an excel file in memory using xlsxwriter and return it via HttpResponse . Here's an example: try: import cStringIO as StringIO except ImportError: import StringIO from django.http import HttpResponse from xlsxwriter.workbook import Workbook def your_view(request): # your view logic here # create a workbook in memory output = StringIO.StringIO() book = Workbook(output) sheet = book.add_worksheet('test') sheet.write(0, 0, 'Hello, world!') book.close() # construct response output.seek(0

I want to use excel files to store data elaborated with python. My problem is that I can't add sheets to an existing excel file. Here I suggest a sample code to work with in order to reach this issue import pandas as pd import numpy as np path = r"C:\Users\fedel\Desktop\excelData\PhD_data.xlsx" x1 = np.random.randn(100, 2) df1 = pd.DataFrame(x1) x2 = np.random.randn(100, 2) df2 = pd.DataFrame(x2) writer = pd.ExcelWriter(path, engine = 'xlsxwriter') df1.to_excel(writer, sheet_name = 'x1') df2.to_excel(writer, sheet_name = 'x2') writer.save() writer.close() This code saves two DataFrames to two
