<h1>SheetJS + Dojo Memory Store Demo</h1>
<br/>
2024-04-26 04:16:13 +00:00
This demo fetches <a href="https://docs.sheetjs.com/pres.xlsx">https://docs.sheetjs.com/pres.xlsx</a>, parses the file, generates a Memory store from the first worksheet, and loads a Combo box. When a President is selected, the text box will display the "Index" field from the dataset.
