 1 | # MiniSheets
 2 | 
 3 | [![Build Status](https://travis-ci.com/kasparsd/mini-sheets-php.svg?branch=master)](https://travis-ci.com/kasparsd/mini-sheets-php)
 4 | 
 5 | Extremely minimal and limited PHP library for creating the most basic Office Open XML and Microsoft Excel XLSX files.
 6 | 
 7 | Created as a learning excerise for creating the most basic possible XLSX file. See [this blog post for the origin story](https://kaspars.net/blog/excel-xlsx-xml-php).
 8 | 
 9 | 
10 | ## Requirements
11 | 
12 | - [`ZipArchive`](https://www.php.net/manual/en/class.ziparchive.php) for creating XLSX files which are actually ZIP files (TODO: add support for any ZIP library).
13 | 
14 | 
15 | ## Usage
16 | 
17 | Install it as a Composer dependency:
18 | 
19 | 	composer require kasparsd/mini-sheets-php
20 | 
21 | See [examples](examples) for how to use it.
22 | 
23 | 
24 | ## Contribute
25 | 
26 | All contributions are welcome! Please create [an issue](https://github.com/kasparsd/mini-sheets-php/issues/new) or [open a pull request](https://github.com/kasparsd/mini-sheets-php/pulls) with the suggested changes.
