You can use SpreadJS and DataViewsJS in the same page.

Add references to SpreadJS first. Then add references to DataViewsJS.

When you reference both controls in the same project, exclude the DataViewJS - gc.dataviews.common.min.js reference.

For example:

<script src="./Spread.Sheets.Release.13.0.0/scripts/gc.spread.sheets.all.13.0.0.min.js"></script>
<link rel="stylesheet" href="./Spread.Sheets.Release.13.0.0/css/gc.spread.sheets.excel2013white.13.0.0.css">
<link rel="stylesheet" href="[Your Stylesheet Path]/gc.dataviews.all.min.css">

<script src="[Your Script Path]/gc.dataviews.all.min.js"></script>
<script src="[Your Script Path]/gc.dataviews.grid.min.js"></script>
