Easy way to do it: download open office (here), load the spreadsheet and open the excel file (.xls or .xlsx). Then just save it as a text CSV file and a window opens asking to keep the current format or to save as a .ODF format. select "keep the current format" and in the new window select the option that works better for you, according with the language that your file is been written on. For Spanish language select Western Europe (Windows-1252/ WinLatin 1) and the file works just fine. If you select Unicode (UTF-8), it is not going to work with the spanish characters.

我写了一个小的Python脚本，可以导出UTF-8格式的工作表。

您只需要提供Excel文件作为第一个参数，然后是要导出的表。如果不提供工作表，脚本将导出Excel文件中存在的所有工作表。

#!/usr/bin/env python

# export data sheets from xlsx to csv

from openpyxl import load_workbook
import csv
from os import sys

reload(sys)
sys.setdefaultencoding('utf-8')

def get_all_sheets(excel_file):
    sheets = []
    workbook = load_workbook(excel_file,use_iterators=True,data_only=True)
    all_worksheets = workbook.get_sheet_names()
    for worksheet_name in all_worksheets:
        sheets.append(worksheet_name)
    return sheets

def csv_from_excel(excel_file, sheets):
    workbook = load_workbook(excel_file,use_iterators=True,data_only=True)
    for worksheet_name in sheets:
        print("Export " + worksheet_name + " ...")

        try:
            worksheet = workbook.get_sheet_by_name(worksheet_name)
        except KeyError:
            print("Could not find " + worksheet_name)
            sys.exit(1)

        your_csv_file = open(''.join([worksheet_name,'.csv']), 'wb')
        wr = csv.writer(your_csv_file, quoting=csv.QUOTE_ALL)
        for row in worksheet.iter_rows():
            lrow = []
            for cell in row:
                lrow.append(cell.value)
            wr.writerow(lrow)
        print(" ... done")
    your_csv_file.close()

if not 2 <= len(sys.argv) <= 3:
    print("Call with " + sys.argv[0] + " <xlxs file> [comma separated list of sheets to export]")
    sys.exit(1)
else:
    sheets = []
    if len(sys.argv) == 3:
        sheets = list(sys.argv[2].split(','))
    else:
        sheets = get_all_sheets(sys.argv[1])
    assert(sheets != None and len(sheets) > 0)
    csv_from_excel(sys.argv[1], sheets)

做到这一点的唯一“简单方法”如下。首先，要意识到Excel .csv文件中显示的内容和隐藏的内容之间是有区别的。

Open an Excel file where you have the info (.xls, .xlsx) In Excel, choose "CSV (Comma Delimited) (*.csv) as the file type and save as that type. In NOTEPAD (found under "Programs" and then Accessories in Start menu), open the saved .csv file in Notepad Then choose -> Save As... and at the bottom of the "save as" box, there is a select box labelled as "Encoding". Select UTF-8 (do NOT use ANSI or you lose all accents etc). After selecting UTF-8, then save the file to a slightly different file name from the original.

该文件采用UTF-8格式，保留所有字符和重音，可以导入，例如，MySQL和其他数据库程序。

这个答案来自这个论坛。

在Excel 2016及更高版本(包括Office 365)中，有一个专门用于UTF-8格式的CSV选项。

在Office 365中，选择另存为;以前人们可能会选择CSV(逗号分隔)，现在你可以保存为CSV UTF-8(逗号分隔)(*.csv)

使用notepad++打开.csv文件。如果你看到你的编码是好的(你看到所有字符，因为他们应该)按编码，然后转换为ANSI Else -找出当前的编码

另一个解决方案是用winword打开文件，并将其另存为txt，然后用excel重新打开，它将工作ISA
