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

我发现OpenOffice的电子表格应用程序Calc非常擅长处理CSV数据。

在“另存为…”对话框中，单击“格式选项”可获得CSV的不同编码。LibreOffice的工作原理与AFAIK相同。

您可以将excel保存为unicode文本，它是制表符分隔的。

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。
