how to find a string in a excel file with qt?

mrjj

Hi
Im not sure what you have tried..
Did you see the sample ?

#include <QtCore>
#include "xlsxdocument.h"

int main()
{
    {
    //Create a new .xlsx file.
    QXlsx::Document xlsx;
    xlsx.write("A1", "Hello Qt!");
    xlsx.write("A2", 12345);
    xlsx.write("A3", "=44+33");
    xlsx.write("A4", true);
    xlsx.write("A5", "http://qt-project.org");
    xlsx.write("A6", QDate(2013, 12, 27));
    xlsx.write("A7", QTime(6, 30));
    xlsx.saveAs("Book1.xlsx");
    }

    QXlsx::Document xlsx("Book1.xlsx");

    qDebug()<<xlsx.read("A1");
    qDebug()<<xlsx.read("A2");
    qDebug()<<xlsx.read("A3");
    qDebug()<<xlsx.read("A4");
    qDebug()<<xlsx.read("A5");
    qDebug()<<xlsx.read("A6");
    qDebug()<<xlsx.read("A7");

    for (int row=1; row<10; ++row) {
        if (QXlsx::Cell *cell=xlsx.cellAt(row, 1))
            qDebug()<<cell->value();
    }

    return 0;
}

It would be easy to loop over the cell and check the data

@mohsen_yadik
you have xlsx file and want to search string from qt?
I'm sorry but I do not understand what you want.

mrjj

@mohsen_yadik

I don't know how to do it.

Which part of it ?
The sample loops over cells.
All that is left is to compare string?

Why did you try so far, please show some code

@mrjj I get the following error when i run this pro QZip: not a zip file!
Any idea whats wrong here ?

mrjj

@Beemaneni-Bala-0
Hi
Can other tool open the zip file ?

@mrjj All i have is only an excel file. I did not understand why and where zip file is needed here ?

mrjj

@Beemaneni-Bala-0
The excel file (XLSX) is actually a zip file.
Do you try to give it an old binary format ?
what is the extension of the file?

@mrjj Here is the code snipped . I need to just read an excel file here. i am using linux machine here and i can open excel file using libreoffice

void MainWindow::readExcelFile(QString excelSheetFile){
    QXlsx::Document xlsx("ExcelSheet.xlsx");

    qDebug()<<xlsx.read("A1");
    qDebug()<<xlsx.read("A2");
    qDebug()<<xlsx.read("A3");
    qDebug()<<xlsx.read("A4");
    qDebug()<<xlsx.read("A5");
    qDebug()<<xlsx.read("A6");
    qDebug()<<xlsx.read("A7");

    for (int row=1; row<10; ++row) {
        qDebug()<<"Row No : "<<row << xlsx.cellAt(row, 1);
        if (QXlsx::Cell *cell=xlsx.cellAt(row, 1))
            qDebug()<< "Cell Data: "  << cell->value();
    }
}

Hi
and the file is indeed an xlsx and not the old xls `?
The file you give it, excelSheetFile
Else convert it with libreOffice

@mrjj Thanks a lot for the information. I had renamed the file to xlsx. That was the issue. After converting using libreoffice it works and i can fetch information.
