# Excel
2+
3+
Excel is a flutter and dart library for creating and updating excel-sheets for XLSX files.
4+
5+
## Usage

7+
### In Flutter App

* var decoder = Excel.createExcel();
20+
*
21+
* ------------ Or ------------

53+
// if [MySheetName] does not exist then it will be automatically created.
54+

55+
56+
decoder
57+

63+
backgroundColorHex: "#1AFF1A")
64+

65+
horizontalAlign: HorizontalAlign.Right);
66+
67+
// Save the file
68+

70+
File(join("/Users/kawal/Desktop/excel.xlsx"))
71+
..createSync(recursive: true)
72+
..writeAsBytesSync(onValue);
73+
});
74+
75+
...
76+
77+
## Features coming in next version
78+
On-going implementation for future:
79+
- spanned rows (Comming Soon in future updates)
80+
- spanned columns (Comming Soon in future updates)
81+
82+
## Important:
83+
For XLSX format, this implementation only supports native Excel format for date, time and boolean type conversion.
84+
In other words, custom format for date, time, boolean aren't supported and also the files exported from LibreOffice as well.
85+
86+
## Support on Beerpay
87+
Hey dude! Help me out for a couple of :beers:!
