Question

我有一个包含数据的~1000 .txt文件的文件夹，我喜欢以相同的方式绘制。这对我来说需要3个挑战： 1）将.txt转换为.xlsx（或.xls - 我不在乎） 2）一次性执行第1步，而不是为要转换的每个文件键入文件名 3）转换文件后，我需要excel将数字识别为数字而不是文本（即目前我必须手动输入＆＃34;文本到列＆＃34;在excel上运行，这对于2列是烦恼的~1000个电子表格）

我有两个代码已经接近（我在网上找到了一些其他代码）。

代码1：

import xlwt
import xlrd
import csv
import openpyxl
import xlsxwriter


mypath = 'C:/desktop/Text Documents/'


from os import listdir
from os.path import isfile, join
textfiles = [ join(mypath,f) for f in listdir(mypath) if isfile(join(mypath,f)) and '.txt' in  f]
for textfile in textfiles:
    f = open(textfile, 'r+')
    row_list = []
    for row in f:
        row_list.append(row.split('\t'))
    column_list = zip(*row_list)
    workbook = xlwt.Workbook()
    worksheet = workbook.add_sheet('Sheet1')
    i = 0
    for column in column_list:
        for item in range(len(column)):
            worksheet.write(item, i, column[item])
        i+=1
    workbook.save(textfile.replace('.txt', '.xls'))

上面是一个文本文件夹，并将它们转换为.xls，并对它们进行分隔，但不幸的是我仍然需要使用＆＃34;文本到列＆＃34;功能

代码2：

import csv
import openpyxl
import xlsxwriter
import xlrd

input_file = 'C:/desktop/Text Documents/thisismytextfilename.txt'
output_file = 'C:/desktop/Text Documents/thisismytextfilename.xlsx'

wb = openpyxl.Workbook()
ws = wb.worksheets[0]

with open(input_file, 'rb') as data:
    reader = csv.reader(data, delimiter='\t')
    for row in reader:
        ws.append(row)


wb.save(output_file)

file_location = output_file

workbook = xlrd.open_workbook(file_location)
sheet = workbook.sheet_by_index(0) #2 indicates 3rd page

x = [sheet.cell_value(i+14, 0) for i in range(sheet.nrows-14)]
y = [sheet.cell_value(i+14, 1) for i in range(sheet.nrows-14)]

workbook = xlsxwriter.Workbook(file_location)
worksheet = workbook.add_worksheet()
bold = workbook.add_format({'bold': 1})

# Add the worksheet data that the charts will refer to.
headings = ['Time (s)', 'Load (kg)']
data = [x,y]

worksheet.write_row('A1', headings, bold)
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])

chart1 = workbook.add_chart({'type': 'scatter'})

# Configure the first series.
chart1.add_series({
    'name': '=Sheet1!$B$1',
    'categories': '=Sheet1!$A$2:$A$25000',
    'values': '=Sheet1!$B$2:$B$25000'})

chart1.set_x_axis({'name': 'Time'})
chart1.set_y_axis({'name': 'Load'})
chart1.set_style(1)

# Insert the chart into the worksheet (with an offset).
worksheet.insert_chart('D2', chart1, {'x_offset': 25, 'y_offset': 10})

workbook.close()

这将提取我想要的2列数据并创建绘图。但我必须复制/粘贴每个文件的文件名，我必须通过并点击＆＃34;文本到列＆＃34;每次。

Answer 1

我必须经历并点击＆＃34;文本到列＆＃34;每次。

您可以使用XlsxWriter constructor参数strings_to_numbers来避免这种情况：

workbook = xlsxwriter.Workbook(filename, {'strings_to_numbers': True})

使用图表将.txt文件的文件夹转换为python中的.xlsx文件夹
