Add a license key before you use the importer or exporter. For example:
GrapeCity.Spread.Sheets.License.LicenseKey = "your key";
If you create a Web application and you also use the script file, then you need to add a license key after you reference the Spread.Sheets script file. For example:
<script>GC.Spread.Sheets.LicenseKey = "your key";</script>
