要使用Qt打开Excel文件,你需要使用Qt的QAxObject类来与Microsoft Office交互。下面是一个简单的代码示例:
```
#include <QAxObject>
QAxObject* excel = new QAxObject("Excel.Application", this);
excel->setProperty("Visible", false);
QAxObject* workbooks = excel->querySubObject("Workbooks");
QAxObject* workbook = workbooks->querySubObject("Open(const QString&)", "path/to/your/excel/file.xlsx");
QAxObject* worksheet = workbook->querySubObject("Worksheets(int)", 1); //打开第一个sheet
QAxObject* range = worksheet->querySubObject("Range(const QString&)", "A1:C3"); //读取A1到C3的单元格
QVariant value = range->property("Value");
QList<QList<QVariant>> data = value.toList(); //将QVariant转换为QList
delete range;
delete worksheet;
workbook->dynamicCall("Close()");
delete workbook;
workbooks->dynamicCall("Close()");
delete workbooks;
excel->dynamicCall("Quit()");
delete excel;
```
这个例子打开一个Excel文件,读取第一个sheet的A1到C3的单元格,并将数据保存在一个QList中。你可以根据自己的需求修改代码。需要注意的是,你需要在项目文件中添加`QT += axcontainer`以使用QAxObject类。
