How does one manipulate the format of the excel sheet using python?
My code currently is taking data from several spreadsheets and is pulling the data I want from these sheets into a single workbook. I want the formatting of the workbook to be consistent, because every iteration of the code just saves over the previously made one.
example I want the Cell A1 to be extended and background of the cell to be blue, but I need A2 background to be red

I am trying to merge individual files into a single file. While merging the data, the requirement is to copy cell colour as well. How can I do this in python?
I have a main dataframe called df1, from this df1 I take six different dataframes based on different conditions. Later I write all this to different excel sheets, So my excel sheet will have 6 sheets.
What I want to do is that I need to colour the column heading of A:D with one colour, E:H to another colour etc. But xlsx writer is already taking time without formatting the file so with formatting it could take much more time.
So I wonder if somehow I can set colour to df1 itself and when taking data from it, all the six df will already have the format property.
What is the best way to do this ?
I have a program which takes DataFrame and writes it into excel as chart(using xlsxwriter and pandas libraries). For example, I wrote column-stacked-chart into excel.
What I want now is to add line chart to that excel chart which was created before. This isn't problem if I write them in the same function, but first chart is already created and I don't have that object in another code. I want to combine them, so I need to get list of charts in excel to take first one, create second and combine them.
I have an Excel file with multiple sheets. With the data I retrieve from another Excel file, I want to add matplotlib charts to each sheet. However, although the plots are generated and shown in the console while the loop runs, once the loop is finished, all the sheets have the last chart added; the one that's supposed to be added to the last sheet.
I tried breaking down the loop and going manually, e.g., plot scheme for sheet[0], for sheet[1], etc. This gave the same result. I don't know if I'm doing something wrong or this is some sort of bug in openpyxl.
sheets = wb.sheetnames
for i in range(0, len(sheets)):
#Iterate over sheets
ws = wb[sheets[i]]
#The chart code
. . .
#I save the current plot to be added to the Excel sheet using openpyxl
fig1.savefig("myplot.png", dpi = 72)
#Add the saved chart to the active excel sheet, which is the current iteration in the loop
img = openpyxl.drawing.image.Image('myplot.png')
ws.add_image(img)
wb.save('Excel_file.xlsx')
At each iteration a new chart is supposed to be added to the active sheet. But I get the last chart in all of them at the end.
The Excel file with the charts added is supposed to be the final form of a fully automated report. I am not using openpyxl's charts instead of matplotlib because I need the flexibility and customizability of the latter.
Any help is appreciated. Many thanks.
I am working in python and using xlwt.
I have got a sample excel sheet and have to generate same excel sheet from python. Now the problem is heading columns are highlighted using some color from excel color palette and I am not able to find the name of color. I need to generate exact copy of sample given to me.
Is there any function in xlwt which let me read color of cell of one sheet and then put that color in my sheet?
Best you read the colours from the sample given to you with xlrd.
If there are only a few different colours and they stay the same over time, you can also open the file in Excel and use a colour picker tool to get the RGB values of the relevant cells.
