# Configuration options

HyperFormula can be customized through easy-to-setup options.

The only mandatory key is licenseKey. It has a dedicated section in which you can find all allowed types of key values.

Below you can see the example of a configuration object and the static method called to initiate a new instance of HyperFormula.

See the full list of available options →

# Example

// define options 
const options = {
    licenseKey: 'gpl-v3',
    precisionRounding: 10,
    nullDate: { year: 1900, month: 1, day: 1 },
    functionArgSeparator: '.'
};

// call the static method to build a new instance
const hfInstance = HyperFormula.buildEmpty(options);
