Spreadsheet formulas

Jspreadsheet implements spreadsheet-like formulas, providing great compatibility with major spreadsheet software, such as Excel or Google Sheets. In this section, you can find which formulas are available, how to create custom formulas and other features.
  • Automatic formula update on copy, paste and corner dragging.
  • The formula returns DOM objects to cells.
  • Cross worksheet calculations.
  • Custom Excel-like formulas

Formula extension distribution

The formulas are available as Basic and Premium. The Basic is the default for all Jspreadsheet distributions, while Premium is distributed as an extension for the Enterprise and Premium plans and provides some extra features such as:
  • Matrix calculations;
  • Range Variables;
  • Extended formulas;
  • Private scope;
  • Special internal properties, x, y and instance;
  • It runs in stand-alone applications;

Special properties for Formulas Premium

When the Jspreasheet Pro invokes the method from a valid cell, you will have access to the coordinates of the cell and the instance of the worksheet.
var YOUR_METHOD = function() {
    // Return the coordinates to the cell
    return this.x + ',' + this.y;
}



Available formulas

We are working to bring as many formulas as possible. Meanwhile, you can check for the existing implementation. For security reasons, all references should use capital letters, including the implementation of custom methods.


Settings

A summary of configurations related to the use of formulas.
Configuration Description
Global configuration for the spreadsheet.
secureFormulas?: boolean Enable formula security. Default: true
editorFormulas?: boolean Enable the formula editor. Default: true
parseFormulas?: boolean Enable formula calculations. Default: true
debugFormulas?: boolean Enable the formula debug notices. Default: true
autoIncrement?: boolean Formula variable increment on cloning or copying. Default: true
Configuration for columns
shiftFormula?: boolean Update the formula on cloning (used for custom columns). Default: true


Spreadsheet formula events

All events related to formulas.
Event Description
onbeforeformula?: Function Intercept and parse a formula just before the execution.
onbeforeformula(worksheet: Object, expression: String, x: Number, y: Number) => String
onformulachain?: Function Get the information about the expressions executed from the formula chain.
onformulachain(worksheet: Object, executions: Object) => void


Spreadsheet methods

All methods related to formulas in the JSS context.
Method Description
executeFormula?: Function Execute a formula.
executeFormula(expression: string, x?: number, y?: number, caching?: boolean, basic?: boolean) => String


Special formulas

To support calculations, Jspreadsheet has a few special formulas listed below:
Method Example
=TABLE() Return the Jspreadsheet table instance
=COLUMN() Return the column number where the formula has been executed
=ROW() Return the row number where the formula has been executed
=CELL() Return the cell string identification
=VALUE() Return the cell value based on the colNumber and rowNumber. You can get the raw or processed value.
=VALUE(col: Number, row: Number, processedValue: Boolean)


Roadmap for the formulas

We are constantly adding new methods and features to bring Jspreadsheet in line with modern software.



Custom formulas

It is possible to create custom methods that will be available in the spreadsheet. The custom method should return the appropriate content for the cell. From version 7 on, Jspreadsheet accepts a DOM element as a return of a function.

IMPORTANT: All method names should be created using capital letters.
// New custom formula
var COLORIZE = function(v) {
    var d = document.createElement('div');
    d.style.color = v;
    d.innerText = v.toUpperCase();
    return d;
}

// Add to the correct scope
formula.setFormula({ COLORIZE });

// Create spreadsheet
jspreadsheet(document.getElementById('spreadsheet'), {
    worksheets: [{
        data: [
            [ 'red', '=COLORIZE(A1)' ],
            [ 'green', '=COLORIZE(A2)' ],
            [ 'blue', '=COLORIZE(A3)' ],
        ],
        columns: [
            { type: 'text', width:'300' },
            { type: 'text', width:'200' },
        ]
    }]
});
