QtXlsx is a library that can read and write Excel files. It doesn't require Microsoft Excel and can be used in any platform that Qt5 supported. The library can be used to

Generate a new .xlsx file from scratch
Extract data from an existing .xlsx file
Edit an existing .xlsx file

Getting Started

For linux user, if your Qt is installed through package manager tools such "apt-get", make sure that you have installed the Qt5 develop package qtbase5-private-dev

Usage(1): Use Xlsx as Qt5's addon module

Building the module

Note: Perl is needed in this step.

Download the source code.
Put the source code in any directory you like
Go to top directory of the project in a terminal and run

    qmake

    make

    make install

The library, the header files, and others will be installed to your system.

make html_docs can be used to generate documentations of the library, and make check can be used to run unit tests of the library.

Using the module

Add following line to your qmake's project file:

    QT += xlsx

Then, using Qt Xlsx in your code

    #include <QtXlsx>

    int main()

    {

        QXlsx::Document xlsx;

        xlsx.write("A1", "Hello Qt!");

        xlsx.saveAs("Test.xlsx");

        return 0;

    }

Usage(2): Use source code directly

The package contains a qtxlsx.pri file that allows you to integrate the component into applications that use qmake for the build step.

Download the source code.
Put the source code in any directory you like. For example, 3rdparty:

    |-- project.pro

    |-- ....

    |-- 3rdparty\

    |     |-- qtxlsx\

    |     |

Add following line to your qmake project file:

    include(3rdparty/qtxlsx/src/xlsx/qtxlsx.pri)

Note: If you like, you can copy all files from src/xlsx to your application's source path. Then add following line to your project file:

include(qtxlsx.pri)



> **Note**: If you do not use qmake, you need to define the following macro manually

> ```

    XLSX_NO_LIB

Then, using Qt Xlsx in your code

    #include "xlsxdocument.h"

    int main()

    {

        QXlsx::Document xlsx;

        xlsx.write("A1", "Hello Qt!");

        xlsx.saveAs("Test.xlsx");

        return 0;

    }

在构建的时候，可能会有如下的错误，

xlsxzipreader.cpp: In member function ‘void QXlsx::ZipReader::init()’:

xlsxzipreader.cpp:51:66: error: conversion from ‘QVector<QZipReader::FileInfo>’ to non-scalar type ‘QList<QZipReader::FileInfo>’ requested

     QList<QZipReader::FileInfo> allFiles = m_reader->fileInfoList();

这里只需要吧出错的文件添加 :
#include <QVector>
然后把出错的地方的"QList" 用"QVector" 替换掉重新构建就可以了。

对于Qt Xlsx （ QtXlsxWriter ）的安装请参考：
http://blog.csdn.net/woshidahuaidan2011/article/details/52724452
这里主要介绍其基本的编程使用方法。
首先我们想到就是对xlsx文件进行读写，因此我们有如下的代码：

#include <QtCore>

#include "xlsxdocument.h"

#include "xlsxformat.h"

#include "xlsxcellrange.h"

#include "xlsxchart.h"

int main()

{

    QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/

    QXlsx::Format format1;/*设置该单元的样式*/

    format1.setFontColor(QColor(Qt::red));/*文字为红色*/

    format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/

    format1.setFontSize(15);/*设置字体大小*/

    format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/

    format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/

    xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/

    xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/

    QXlsx::Format format2;/*重新设置另一个单元的样式*/

    format2.setFontBold(true);/*设置加粗*/

    format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/

    format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/

    xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/

    xlsx.write("C4", true, format2);

    xlsx.saveAs("book1.xlsx");/*保存*/

    QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/

    xlsx2.saveAs("Book2.xlsx");

    return 0;

}

其运行效果如下：

接下来我们处理数据的是很多时候需要插入折线图、饼状图等等来图像化的处理数据，因此我们可以可以在原有代码上添加一段代码，使之添加一个sheet而且插入饼状图及其条形图：

#include <QtCore>

#include "xlsxdocument.h"

#include "xlsxformat.h"

#include "xlsxcellrange.h"

#include "xlsxchart.h"

int main()

{

    QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/

    QXlsx::Format format1;/*设置该单元的样式*/

    format1.setFontColor(QColor(Qt::red));/*文字为红色*/

    format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/

    format1.setFontSize(15);/*设置字体大小*/

    format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/

    format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/

    xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/

    xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/

    QXlsx::Format format2;/*重新设置另一个单元的样式*/

    format2.setFontBold(true);/*设置加粗*/

    format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/

    format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/

    xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/

    xlsx.write("C4", true, format2);

    if(!xlsx.selectSheet("ziv")){/*在当前打开的xlsx文件中，找一个名字为ziv的sheet*/

        xlsx.addSheet("ziv");//找不到的话就添加一个名为ziv的sheet

    }

    for (int i=10; i<20; ++i) {/*写入一串数字*/

        xlsx.write(i, 1, i*i*i);   //A10:A19

        xlsx.write(i, 2, i*i); //B10:B19

        xlsx.write(i, 3, i*i-1); //C10:C19

    }

    QXlsx::Chart *pieChart = xlsx.insertChart(3, 5, QSize(300, 300));/*在3行5列的位置插入一个图标*/

    pieChart->setChartType(QXlsx::Chart::CT_Pie);/*插入一个饼形图*/

    pieChart->addSeries(QXlsx::CellRange("A10:A19"));/*饼形图添加数据*/

    pieChart->addSeries(QXlsx::CellRange("B10:B19"));

    pieChart->addSeries(QXlsx::CellRange("C10:C19"));

    QXlsx::Chart *barChart = xlsx.insertChart(3, 13, QSize(300, 300));/*在3行13列的位置插入一个图标*/

    barChart->setChartType(QXlsx::Chart::CT_Bar);/*条形图*/

    barChart->addSeries(QXlsx::CellRange("A10:C19"));/*给条形图加入数据*/

    xlsx.saveAs("book1.xlsx");/*保存*/

    QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/

    xlsx2.saveAs("Book2.xlsx");

    return 0;

}

上面代码中运行效果如下：

很多时候我们还需要添加图表来美化表格，代码如下：

#include <QtCore>

#include <QtGui>

#include "xlsxdocument.h"

#include "xlsxformat.h"

#include "xlsxcellrange.h"

#include "xlsxchart.h"

int main()

{

    QXlsx::Document xlsx("book1.xlsx");/*打开一个book1的文件*/

    QXlsx::Format format1;/*设置该单元的样式*/

    format1.setFontColor(QColor(Qt::red));/*文字为红色*/

    format1.setPatternBackgroundColor(QColor(152,251,152));/*北京颜色*/

    format1.setFontSize(15);/*设置字体大小*/

    format1.setHorizontalAlignment(QXlsx::Format::AlignHCenter);/*横向居中*/

    format1.setBorderStyle(QXlsx::Format::BorderDashDotDot);/*边框样式*/

    xlsx.write("A1", "Hello Qt!", format1);/*写入文字，应该刚才设置的样式*/

    xlsx.write(2, 1, 12345, format1);/*写入文字，应该刚才设置的样式*/

    QXlsx::Format format2;/*重新设置另一个单元的样式*/

    format2.setFontBold(true);/*设置加粗*/

    format2.setFontUnderline(QXlsx::Format::FontUnderlineDouble);/*下双划线*/

    format2.setFillPattern(QXlsx::Format::PatternLightUp);/*填充方式*/

    xlsx.write("A4", "=44+33", format2);/*写入文字，应该刚才设置的样式*/

    xlsx.write("C4", true, format2);

    if(!xlsx.selectSheet("ziv")){/*在当前打开的xlsx文件中，找一个名字为ziv的sheet*/

        xlsx.addSheet("ziv");//找不到的话就添加一个名为ziv的sheet

    }

    for (int i=10; i<20; ++i) {/*写入一串数字*/

        xlsx.write(i, 1, i*i*i);   //A10:A19

        xlsx.write(i, 2, i*i); //B10:B19

        xlsx.write(i, 3, i*i-1); //C10:C19

    }

    QXlsx::Chart *pieChart = xlsx.insertChart(3, 5, QSize(300, 300));/*在3行5列的位置插入一个图标*/

    pieChart->setChartType(QXlsx::Chart::CT_Pie);/*插入一个饼形图*/

    pieChart->addSeries(QXlsx::CellRange("A10:A19"));/*饼形图添加数据*/

    pieChart->addSeries(QXlsx::CellRange("B10:B19"));

    pieChart->addSeries(QXlsx::CellRange("C10:C19"));

    QXlsx::Chart *barChart = xlsx.insertChart(3, 13, QSize(300, 300));/*在3行13列的位置插入一个图标*/

    barChart->setChartType(QXlsx::Chart::CT_Bar);/*条形图*/

    barChart->addSeries(QXlsx::CellRange("A10:C19"));/*给条形图加入数据*/

    QImage image(40, 100, QImage::Format_RGB32);/*新建一个Qimage,大小40*100*/

    image.fill(Qt::green);/*填充绿色*/

    xlsx.insertImage(1, 1, image);/*插入图片*/

    xlsx.saveAs("book1.xlsx");/*保存*/

    QXlsx::Document xlsx2("Book1.xlsx");/*复制book1到book2*/

    xlsx2.saveAs("Book2.xlsx");

    return 0;

}

效果如下：

到此为止对于Qt Xlsx 的使用应该可以满足大部分的需求，如有疑问欢迎留言指正，原文地址:
