Trial Version and Licensing

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

SpreadJS License

Use the following steps to license the SpreadJS file:

1. Extract the downloaded SpreadJS.Release.XX.XX.X.zip file.

2. Add a reference to the SpreadJS license you received while purchasing the product. Add the reference before the workbook is initialized.

   For example:

   <script src="./scripts/gc.spread.sheets.all.0.0.0.min.js"></script>
   <script>
      GC.Spread.Sheets.LicenseKey = "xxxx";      // Enter a valid license key.  
   </script>

   Or

   <script src="./scripts/gc.spread.sheets.all.0.0.0.min.js"></script>
   <script src="./scripts/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 = "xxxx";        // Enter a valid license key.  

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).

SpreadJS also supports various JavaScript Frameworks. Use SpreadJS in the application and add a valid SpreadJS license key before initializing the component, if available.

<script>
    GC.Spread.Sheets.LicenseKey = "xxxx";        // Enter a valid license key.      
</script>

Add-on License

You can choose to purchase the SpreadJS license along with the add-on features. The following table describes the product behavior in both cases:

Note: If the Pivot Table, GanttSheet, ReportSheet, or Designer Ribbon Component script is added and used locally without a key, a watermark will be displayed. If you use the script in your application, it must have the SpreadJS production license key activated for that feature.

SpreadJS Designer

SpreadJS Designer is a stand-alone desktop application and is available for 30 days as a trial without a license key.

Select the lock button and enter a valid license key to activate the SpreadJS Designer before the trial ends.
