The SpreadJS evaluation version displays a watermark at the lower-right corner. For example:

To update your JavaScript to use the licensed version, you must download and extract the licensed JavaScript from the link included in your email from spread.sales@grapecity.com.

SpreadJS

Use the following steps to extract the licensed files:

1. Extract the downloaded SpreadJSLicensedX.XX.XXXX.X.zip to the same location as the trial and replace all existing files at that location.

2. Add a reference to your SpreadJS license that you received when you purchased the product. Add the reference before the workbook is initialized. For example:

   <script src="./scripts/evaluation/gc.spread.sheets.all.12.0.0.min.js" type="application/javascript"></script>
<script>
   GC.Spread.Sheets.LicenseKey = "xxx";
</script>

   Or

   <script src="./scripts/evaluation/gc.spread.sheets.all.12.0.0.min.js" type="application/javascript"></script>
       <script src="./scripts/evaluation/licensekey.js" type="application/javascript"></script>
       <script>
        window.onload = function () {
            var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
            var activeSheet = spread.getActiveSheet();
         }
  </script>
 
licensekey.js file:
   GC.Spread.Sheets.LicenseKey = "xxxxxx";

Note: If you do not have a trial or production license, SpreadJS can only be used on the local machine (for example: http(s)://localhost or http(s)://127.0.0.1).
