QT ：QAxObject操作Excel

QT += axcontainer
#include <QAxObject>

    QString filePath = QDir::toNativeSeparators(_filePath);
    QAxObject *excel = new QAxObject();//建立excel操作对象
    excel->setControl("Excel.Application");//连接Excel控件
    excel->setProperty("Visible", false);//显示窗体看效果
    excel->setProperty("DisplayAlerts", false);//显示警告看效果
    QAxObject *workbooks = excel->querySubObject("WorkBooks");//获取工作簿(excel文件)集合
    workbooks->dynamicCall("Open(const QString&)", filePath);
    QAxObject *workbook = excel->querySubObject("ActiveWorkBook");//获取当前工作簿
    QAxObject *worksheet = workbook->querySubObject("WorkSheets(int)", 1);

    QAxObject* cell = worksheet->querySubObject("Cells(int, int)", 1, 1);//获取单元格
    QVariant cellValue = cell->property("Value");//获取值
    cell->setProperty("Value", QVariant(uuid));//设置值

    workbook->dynamicCall("Save()"); //保存文件
    workbook->dynamicCall( "Close(Boolean)", false);//关闭文件
    excel->dynamicCall("Quit(void)");//关闭excel
    delete excel;
