Trial Version and Licensing

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@mescius.com.

Extracting Licensed files

Use the following steps to extract the licensed files:

1. Extract the downloaded SpreadJSRelease.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.0.0.0.min.js" type="application/javascript"></script>
   <script>
      GC.Spread.Sheets.LicenseKey = "xxx";
   </script>

   Or

   <script src="./scripts/evaluation/gc.spread.sheets.all.14.1.0.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).

Add-on License

In version 14.1 or later, you can choose to purchase the SpreadJS license along with the Pivot table add-on. The following table describes the product behavior in both the cases:

Note: If the Pivot Table script is added and used locally without a key, a watermark will be displayed. If this script is deployed in your application, it must have a Pivot Table enabled SpreadJS production license key.

SpreadJS Designer

The SpreadJS Designer is available for 30 days as a trial without a license key.

Select the lock icon and enter your license key to unlock the SpreadJS Designer.

Please note that the SpreadJS Designer application includes the pivot table add-on in version 14.1 or later, by default.
