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_docscan be used to generate documentations of the library, andmake checkcan 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。
