Very simple and robust OpenXML file creator – it allows creating an *.xlsx Excel file.
Features
Limitations
It provides no means of formatting and currently allows providing only the following types of values to cells:
- numbers
- percentages (without formatting of decimal places - it will be shown rounded, but the stored value will have the original precision)
- text
Should you require other features, feel free to extend this library or find a more complex library - there are many available.
