# XlsxStream

[![Hex.pm](https://img.shields.io/hexpm/v/xlsx_stream.svg)](https://hex.pm/packages/xlsx_stream)

A xlsx library could take two kind of approach

1) A simple api which supports limited functionality of xlsx

file. This would mostly take a list like data as input and would

create a xlsx file from it. Customization like custom style, custom

field width etc would be hard or not possible to implement via this

approach.

2) Provide the necessary low-level constructs required to create a

xlsx file. The user needs to be familiar with the xlsx

specification. But on the plus side, any kind of customization could

be done easily.

This library takes the second approach.

A [xlsx](http://officeopenxml.com/anatomyofOOXML-xlsx.php) file is a

zip file containing a number of XML files. This library utilizes

[xml_stream](https://github.com/activesphere/xml_stream) and

[zstream](https://github.com/ananthakumaran/zstream) to create XML

files and zip them as a stream. Check the test file for full example.
