使用 xlsxwriter 将文本文件数据迁移到 excel 未完全更新

Question

test.txt: A 25 12345 B 90 67890 C 31 24680 D 89 45678

expected output: A1 A A2 25 A3 12345 A4 B A5 90 A6 67890 ......

only last three data is coming in the excel

import xlsxwriter

workbook = xlsxwriter.Workbook('demo.xlsx')
worksheet = workbook.add_worksheet()

with open('test.txt', 'r') as f:
    for i in f.readlines():
        for j,k in enumerate(i.split()):
            worksheet.write('A'+str(j+1), k)
    workbook.close()

Answer 1

Inside the inner loop, j will always be the enumeration 0,1,2 and so you are repeatedly writing to cells A1 , A2 , and A3 . You can see this for yourself if you print the result to your console:

A1 A
A2 25
A3 12345
A1 B
A2 90
A3 67890
A1 C
A2 31
A3 24680
A1 D
A2 89
A3 45678

You always want to increase the number in the first argument of write so the next row gets indexed; the value to increase with is the length of the splitted list ( 3 for your current input but to make sure I use the actual length of each line below). Because Excel starts counting rows at 1 , this counter needs to start with 1 as well. This will work:

counter = 1
for i in f.readlines():
    for j,k in enumerate(i.split()):
         worksheet.write('A'+str(j+counter), k)
    counter += len(i.split())

Like your own code and the expected output, all it will do is fill the first column only, with each value in the input, ignoring the line breaks.
