TIP
To use HyperFormula within Handsontable's default Formulas plugin, you only need your existing Handsontable license key.
To use HyperFormula independently from Handsontable, you need a license key dedicated to HyperFormula. For details, contact our Sales Team (opens new window).
Overview
The Formulas plugin provides you an extensive calculation capabilities based on formulas using the spreadsheet notation. Under the hood, it uses an engine called HyperFormula (opens new window) created by the Handsontable team as an independent library to help developers build complex data management apps.
This plugin comes with a library of 386 functions grouped into categories, such as Math and trigonometry, Engineering, Statistical, Financial, and Logical. Using these, you can create complex data entry rules in business apps and much more. Below are some ideas on what you can do with it:
- Fully-featured spreadsheet apps
- Smart documents
- Educational apps
- Business logic builders
- Forms and form builders
- Online calculators
- Low connectivity apps
HyperFormula version support
Different versions of Handsontable support different versions of HyperFormula.
To find out which HyperFormula version to use, see the table below:
HyperFormula version support
Handsontable version | HyperFormula version |
---|---|
8.x.x (opens new window) and lower | No HyperFormula support (old Formulas (opens new window) plugin) |
9.x.x (opens new window) | 0.6.2 (opens new window) |
10.x.x (opens new window) | ^1.2.0 (opens new window) |
11.x.x (opens new window) | ^1.2.0 (opens new window) |
12.x.x (opens new window) and higher | ^2.0.0 (opens new window) |

Available options and methods
For the list of available settings and methods, visit the API reference.
Available functions
This plugin inherits the calculation powers from HyperFormula. The complete functions reference can be found in the HyperFormula documentation (opens new window).
Basic multi-sheet example
It is possible to use the plugin in single sheet mode or with multiple Handsontable instances with cross-sheet references.
Double click on a cell to open the editor and preview the formula.
Data grid example
This example is more typical of data grids than spreadsheets. Calculations are present in two places – in a column “Total due (fx)”, and in the summary row at the bottom.
Initialization methods
There're multiple ways of initializing the plugin. You can select the most convenient one depending on your use case.
In all cases, it is required to either pass in the HyperFormula
object or a HyperFormula instance:
import { HyperFormula } from 'hyperformula';
There are also other installation methods available. Check out HyperFormula's installation documentation (opens new window).
HyperFormula instance
To use the Formulas
plugin with an external HyperFormula instance,
initialize HyperFormula with the 'internal-use-in-handsontable'
license key:
// create an external HyperFormula instance
const hyperformulaInstance = HyperFormula.buildEmpty({
// initialize it with the `'internal-use-in-handsontable'` license key
licenseKey: 'internal-use-in-handsontable',
});
Passing the HyperFormula class/instance to Handsontable
{
formulas: {
engine: HyperFormula,
// [plugin configuration]
}
}
or
{
formulas: {
engine: {
hyperformula: HyperFormula, // or `engine: hyperformulaInstance`
leapYear1900: false,
// ...and more engine configuration options.
// See https://handsontable.github.io/hyperformula/api/interfaces/configparams.html#number
},
// [plugin configuration]
}
}
Single Handsontable instance with an external HyperFormula instance
const hyperformulaInstance = HyperFormula.buildEmpty({
// to use an external HyperFormula instance,
// initialize it with the `'internal-use-in-handsontable'` license key
licenseKey: 'internal-use-in-handsontable',
});
{
formulas: {
engine: hyperformulaInstance
}
}
Multiple independent Handsontable instances
// Instance 1
{
formulas: {
engine: HyperFormula,
// [plugin configuration]
}
}
// Instance 2
{
formulas: {
engine: HyperFormula,
// [plugin configuration]
}
}
Multiple Handsontable instances with a shared HyperFormula instance
// Instance 1
{
formulas: {
engine: HyperFormula,
sheetName: 'Sheet1'
// [plugin configuration]
}
}
// Instance 2
{
formulas: {
engine: hot1.getPlugin('formulas').engine,
sheetName: 'Sheet2'
// [plugin configuration]
}
}
Multiple Handsontable instances with an external shared HyperFormula instance
const hyperformulaInstance = HyperFormula.buildEmpty({
// to use an external HyperFormula instance,
// initialize it with the `'internal-use-in-handsontable'` license key
licenseKey: 'internal-use-in-handsontable',
});
// Instance 1
{
formulas: {
engine: hyperformulaInstance,
sheetName: 'Sheet1'
// [plugin configuration]
}
}
// Instance 2
{
formulas: {
engine: hyperformulaInstance,
sheetName: 'Sheet2'
// [plugin configuration]
}
}
afterFormulasValuesUpdate
hook
This hook listens for any changes to cells in the calculation engine, including dependent cells containing formulas.
const afterFormulasValuesUpdate = (changes) => {
changes.forEach((change) => {
console.log('change', change.address, change.newValue)
})
}
new Handsontable(element, {
formulas: {
engine: HyperFormula
},
afterFormulasValuesUpdate
})
Named expressions
You can use custom-named expressions in your formula expressions. A named expression can be either plain values or formulas with references to absolute cell addresses. To register a named expression, pass an array with name
and expression
to your formulas
configuration object:
For more information about named expressions, please refer to the HyperFormula docs (opens new window).
