清洁Excel表（替换文本）

Question

我有一个程序，可以从网站上抓取表格并将其放入xls表中。但是，大多数数据必须是数字，某些单元格可能包含257,2x，ȻC，KL1等。我无法找出一种简单的方法用“”替换多余的字符，因为显然Apache POI并没有允许这个吗？ 那么，您如何建议我这样做？ 预先感谢。

int kansio = 1;
    Document doc3 = Jsoup.connect("https://ravit.is.fi/paivanravit/").get();
    Element table2 = doc3.select("table").get(5);
    Elements links2 = table2.select("a[href]"); // a with href
    for (Element link3 : links2) {
        int asd1 = 1;
        new File("C:\\sheets\\lahto-" + kansio).mkdir();
        Document doc2 = Jsoup.connect("https://ravit.is.fi/paivanravit/" + link3.attr("href")).get();
        Elements links = doc2.select("[href*=hevoset]");
        for (Element link2 : links) {

            try {
