How do I output a list of dictionaries to an Excel sheet?

I have a list called 'players' that consists of dictionaries. It looks like this:

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

It's much longer, but this is an excerpt. How do I output this list of dictionaries to an Excel file so it's neatly organized by key/value?

Solution using Pandas

import pandas as pd

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFreePlayed': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player4', 'bank': 0.32}]

df = pd.DataFrame.from_dict(players)

print (df)

df.to_excel('players.xlsx')

There is a way to write a list of dictionary to an Excel worksheet. First of all, be sure you have XlsxWriter package.

from xlsxwriter import Workbook
players = [{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

ordered_list=["user", "dailyWinners", "dailyFree", "bank"] # List object calls by index, but the dict object calls items randomly

wb=Workbook("New File.xlsx")
ws=wb.add_worksheet("New Sheet") # Or leave it blank. The default name is "Sheet 1"

first_row=0
for header in ordered_list:
    col=ordered_list.index(header) # We are keeping order.
    ws.write(first_row,col,header) # We have written first row which is the header of worksheet also.

row=1
for player in players:
    for _key,_value in player.items():
        col=ordered_list.index(_key)
        ws.write(row,col,_value)
    row+=1 #enter the next row
wb.close()

I tried the code, and it worked successfully.

The xlsxwriter library is great for creating .xlsx files (originally mentioned by Fatih1923).

The following snippet generates an .xlsx file from a list of dicts while stating the order and the displayed names:

import xlsxwriter

# ...

def create_xlsx_file(file_path: str, headers: dict, items: list):
    with xlsxwriter.Workbook(file_path) as workbook:
        worksheet = workbook.add_worksheet()
        worksheet.write_row(row=0, col=0, data=headers.values())
        header_keys = list(headers.keys())
        for index, item in enumerate(items):
            row = map(lambda field_id: item.get(field_id, ''), header_keys)
            worksheet.write_row(row=index + 1, col=0, data=row)

Usage

headers = {
    'bank': 'Money in Bank',
    'dailyWinners': 'Daily Winners',
    'dailyFree': 'Daily Free',
    'user': 'User',
}

players = [
    {'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
    {'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
    {'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
    {'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}
]

create_xlsx_file("my xslx file.xlsx", headers, players)

💡 Note - The headers dict represent both the order and the displayed name. If you're not using Python3.6+, use OrderedDict in headers, since the order in dict is not preserved

test.py

from csv import DictWriter

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},            
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

with open('spreadsheet.csv','w') as outfile:
    writer = DictWriter(outfile, ('dailyWinners','dailyFreePlayed','dailyFree','user','bank'))
    writer.writeheader()
    writer.writerows(players)

Run python test.py

Then open the resulting spreadsheet.csv file in Excel.

NOTE: I'm running Linux so I wasn't able to test this using Microsoft Excel. This works in LibreOffice Calc and gives a spreadsheet where the keys are the column names and the values are under their appropriate columns.
