使用xlrd模块读取xlsx文件并作为CSV文件写入

Question

I am using xlrd to read an xslx file and write it in csv format. When I open the csv file after running the code, there is an empty row after each filled one. I would like the information in the csv file to be a bit more condensed without any empty rows.

Here is my code:

import xlrd
import csv

def csv_from_excel():
    workbook = xlrd.open_workbook('refugee_camp.xlsx')
    sheet = workbook.sheet_by_index(0)
    converted_csv = open('refugeecamp.csv', 'w')
    wr = csv.writer(converted_csv, quoting=csv.QUOTE_ALL)

    for rownum in range(sheet.nrows):
        wr.writerow(sheet.row_values(rownum))

    converted_csv.close()
    try:
        open_file = open("refugeecamp.csv", 'r')
        print("Yesss")
    except: 
        print("could not open file!")

csv_from_excel()

The first 9 rows of data:

Here is a link to the xlxs datafile

Answer 1

Welcome to SO! The empty rows are caused not because of data. You need to add a parameter while opening the csv file object called newline . Rewrite your code like,

with open('refugeecamp.csv', 'w', newline='') as converted_csv:
    writer = csv.writer(converted_csv, quoting=csv.QUOTE_ALL)

Refer this answer for more details.

Hope this helps! Cheers!
