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 (opens new window) (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.

Which versions of HyperFormula a key covers, and for how long, follows from the terms of your contract. Your key carries those terms, and HyperFormula applies them locally, without any connection to a server.

Feature packages and add-ons

A proprietary license key may grant the whole library, or only part of it.

If your key grants only part of the library, then:

• A function your key doesn't include evaluates to a #LIC! error, in the same way as any other error value. Everything else in the sheet keeps calculating.
• An API method your key doesn't include throws a LicenseCapabilityMissingError when you call it. Getters never throw; copy() and cut() do, because they belong to the clipboard feature.
• getAvailableFunctions() and getFunctionDetails() describe only the functions your key includes, so a function picker built from them never offers a function that then fails.

License key notifications

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

In that case every licence-gated function call evaluates to a #LIC! error — but no API method starts throwing, and getAvailableFunctions() still describes the full set of functions. A key problem never narrows what the library reports it can do.
