<b><a href="https://sheetjs.com">SheetJS + KnockoutJS demo</a></b>
|
|
|
|
The core library can be used as-is in KnockoutJS applications.
|
|
The <a href="https://docs.sheetjs.com">Community Edition README</a> details some common use cases.
|
|
We also have some <a href="https://docs.sheetjs.com/docs/demos/">more public demos</a>
|
|
|
|
This demo shows:
|
|
- view model backed by an array of arrays
|
|
- file import that refreshes the model
|
|
- table of editable `input` elements that are bound to the model
|
|
- file export based on the model
|
|
|
