License key

To use HyperFormula, you need to specify which license type you use, by entering a license key in your configuration options.

GPLv3 license

If you use HyperFormula under GNU General Public License v3.0 (GPLv3), in your configuration options, assign the mandatory licenseKey property to a string, gpl-v3:

const options = {
  licenseKey: 'gpl-v3',
  //... other options
}

Proprietary license

To use HyperFormula under a proprietary license, follow these steps:

1. Contact our Sales Team to purchase a proprietary license.
2. Our Sales Team sends you your proprietary license key.
3. In your configuration options, assign the mandatory licenseKey property to your proprietary license key:

const options = {
  // replace xxxx-xxxx-xxxx-xxxx-xxxx with your proprietary license key:
  licenseKey: 'xxxx-xxxx-xxxx-xxxx-xxxx',
  //... other options
}

Proprietary license key validation

Tip

HyperFormula doesn’t use an internet connection to validate your proprietary license key.

To determine whether a user is still entitled to use a particular version of the software, HyperFormula compares the time between two dates:

• The HyperFormula build date
• The date in your proprietary license key

This process doesn’t require any connection to the server.

License key notifications

If your license key is missing, invalid, or expired, you see a corresponding notification in the console.
