对于那些寻找完全程序化(或者至少是服务器端)解决方案的人来说，我使用catdoc的xls2csv工具取得了巨大的成功。

安装catdoc:

apt-get install catdoc

进行转换:

xls2csv -d utf-8 file.xls > file-utf-8.csv 

这是非常快的。

请注意，包含-d utf-8标志非常重要，否则它将以默认的cp1252编码方式对输出进行编码，并且您将面临丢失信息的风险。

注意，xls2csv也只适用于.xls文件，它不适用于.xlsx文件。

简单的方法: 不需要Open office和谷歌文档

Save your file as "Unicode text file"; now you have an unicode text file open it with "notepad" and "Save as" it with selecting "utf-8" or other code page that you want rename file extension from "txt" to "csv". This will result in a tab-delimited UTF-8 csv file. If you want a comma-delimited file, open the csv file you just renamed and replace all tabs with commas. To do this in Notepad on Win 10, simply select one tab field then click Ctrl+H. In the window that opens, type a comma , in the "Replace with" field then click "Replace All". Save your file. The result will be a comma-delimited UTF-8 csv file.

不管怎样，不要用ms office打开它!! 现在您有了一个以制表符分隔的CSV文件。 或者，如果应用步骤5，则使用逗号分隔。

我使用了以下解决方案:Mac Exel 2008 >文件>另存为格式，然后在格式下使用MS_DOS逗号分隔(.csv)。完美的工作。

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)

将xls文件(Excel文件)保存为Unicode text=>文件将保存为文本格式(.txt) 将格式从.txt更改为.csv(将文件从xyz .txt重命名为xyz .csv

I needed to automate this process on my Mac. I originally tried using catdoc/xls2csv as suggested by mpowered, but xls2csv had trouble detecting the original encoding of the document and not all documents were the same. What I ended up doing was setting the default webpage output encoding to be UTF-8 and then providing the files to Apple's Automator, applying the Convert Format of Excel Files action to convert to Web Page (HTML). Then using PHP, DOMDocument and XPath, I queried the documents and formatted them to CSV.

这是PHP脚本(process.php):

<?php
$pi = pathinfo($argv[1]);
$file = $pi['dirname'] . '/' . $pi['filename'] . '.csv';
$fp = fopen($file,'w+');
$doc = new DOMDocument;
$doc->loadHTMLFile($argv[1]);
$xpath = new DOMXPath($doc);
$table = [];
foreach($xpath->query('//tr') as $row){
    $_r = [];
    foreach($xpath->query('td',$row) as $col){
        $_r[] = trim($col->textContent);
    }
    fputcsv($fp,$_r);
}
fclose($fp);
?>

这是我用来将HTML文档转换为csv的shell命令:

find . -name '*.htm' | xargs -I{} php ./process.php {}

这是一种非常非常迂回的方法，但这是我发现的最可靠的方法。
