## Introduction
-Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLAM / XLSM / XLSX / XLTM / XLTX files. Supports reading and writing spreadsheet documents generated by Microsoft Excel™ 2007 and later. Supports complex components by high compatibility, and provided streaming API for generating or reading data from a worksheet with huge amounts of data. This library needs Go version 1.15 or later. The full API docs can be seen using go's built-in documentation tool, or online at [go.dev](https://pkg.go.dev/github.com/xuri/excelize/v2) and [docs reference](https://xuri.me/excelize/).
