PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc. Support for PHP versions will only be maintained for a period of six months beyond the end of life of that PHP version. Use composer to install PhpSpreadsheet into your project. Or also download the documentation and samples if you plan to use them. A good way to get started is to run some of the samples. Don't forget to download them via --prefer-source composer flag. And then serve them via PHP built-in webserver. PhpSpreadsheet relies on Composer autoloader. So before working with PhpSpreadsheet in standalone, be sure to run composer install.

    SimpleXlsxWriter

    C++ library for creating XLSX files for MS Excel 2007 and above.

    This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written. Hence, if using this library the structure of the future report should be known enough. The library is written in C++ with using STL functionality and based on the ZIP library (included), which has a free license: http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32 This library is distributed under the terms of the zlib license: http://www.zlib.net/zlib_license.html

    Savvy Repair for Microsoft Office

    Savvy Repair for Microsoft Office

    Repairs/Recovers Corrupt MS Office 2007 - 2013 Format Files

    DOCX, XLSX and PPTX files are collections of conventionally zipped mostly XML sub-files. This program first attempts repair any zip based corruption. From there it engages in four different algorithmic attempts at repair or recovery. With the first method using validation, the location of the first XML error is sought. At that point the sub-files are truncated and repaired. The second method works the same way except the XML validation is more lax. With the third, the strict XML validation is returned to and corrupt XML sub-files are truncated and repaired as before however, missing XML sub-files are brought in from blank full healthy docx, xlsx or pptx of the respective correct extension. The fourth method uses SilverCoder's DocToText to salvage text or data after which the file is opened as an old style MS Office 97 - 2003 format file including the naked recovered text or data. See my other projects here on Sourceforge for other ways to recover corrupt MS and Open Office files.
