记录0x5B的初始化剩余1个字节仍有待读取。ApachePOIJava

加载excel文件并将其保存到某个较新版本的excel中。然后使用这个新文件进行测试。
并使用最新版本的POI。谷歌搜索者可能感兴趣的另一个解决方案是使用libre office headless convert,它将在Linux上工作。粘贴和修改代码
String[] commandArray = new String[]{
"libreoffice"
,"--headless"
,"--convert-to"
,"xlsx:Calc MS Excel 2007 XML"
,"--outdir"
,Paths.get(file.getPath()).getParent().toString()
,file.getPath()
};
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(commandArray);
InputStream stin = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stin);
BufferedReader br = new BufferedReader(isr);
String line;
System.out.println("input");
while ((line = br.readLine()) != null) {
System.out.println(line);
}
stin = proc.getErrorStream();
isr = new InputStreamReader(stin);
br = new BufferedReader(isr);
while ((line = br.readLine()) != null) {
System.out.println(line);
}
int exitVal = proc.waitFor();
System.out.println("Process exitValue: " + exitVal);
OPCPackage opcPackage = OPCPackage.open(new File(file.getPath() + "x"));
book = new XSSFWorkbook(opcPackage);
这是一条异常消息还是什么?@LuiggiMendoza yea这是一个异常,我想是因为xls格式比较旧,因为当我将其保存为97-2003工作簿时,它可以工作..好的,工作正常,但我将拥有的这些xls文件将是旧格式。。有什么方法可以使用这些格式吗?因为POI无法打开旧格式,请尝试进行一些自动转换。选中此项:
