A function can also return a range of data. Excel will pass a range of cell data as a two-dimensional array.For example, suppose that your function returns the second highest value from a range of numbers stored in Excel. The following function accepts the parameter values, and the JSDOC syntax number[][] sets the parameter's dimensionality property to matrix in the JSON metadata for this function./** * Returns the second highest value in a matrixed range of values. * @customfunction * @param {number[][]} values Multiple ranges of values. */function secondHighest(values) { let highest = values[0][0], secondHighest = values[0][0]; for (let i = 0; i = highest) { secondHighest = highest; highest = values[i][j]; } else if (values[i][j] >= secondHighest) { secondHighest = values[i][j]; } } } return secondHighest;}Repeating parametersA repeating parameter allows a user to enter a series of optional arguments to a function. When the function is called, the values are provided in an array for the parameter. If the parameter name ends with a number, each argument's number will increase incrementally, such as ADD(number1, [number2], [number3],…). This matches the convention used for built-in Excel functions.The following function sums the total of numbers, cell addresses, as well as ranges, if entered./*** The sum of all of the numbers.* @customfunction* @param operands A number (such as 1 or 3.1415), a cell address (such as A1 or $E$11), or a range of cell addresses (such as B3:F12)*/function ADD(operands: number[][][]): number { let total: number = 0; operands.forEach(range => { range.forEach(row => { row.forEach(num => { total += num; }); }); }); return total;}This function shows =CONTOSO.ADD([operands], [operands]...) in the Excel workbook.Repeating single value parameterA repeating single value parameter allows multiple single values to be passed. For example, the user could enter ADD(1,B2,3). The following sample shows how to declare a single value parameter./** * @customfunction * @param {number[]} singleValue An array of numbers that are repeating parameters. */function addSingleValue(singleValue) { let total = 0; singleValue.forEach(value => {

Custom functions parameter options Article07/05/2023 In this article -->Custom functions are configurable with many different parameter options.ImportantNote that Excel custom functions are available on the following platforms.Office on the webOffice on WindowsMicrosoft 365 subscriptionretail perpetual Office 2016 and latervolume-licensed perpetual Office 2021 and laterOffice on MacExcel custom functions aren't currently supported in the following:Office on iPadvolume-licensed perpetual versions of Office 2019 or earlier on WindowsNoteThe unified manifest for Microsoft 365 doesn't currently support custom functions projects. You must use the add-in only manifest for custom functions projects. For more information, see Office Add-ins manifest.Optional parametersWhen a user invokes a function in Excel, optional parameters appear in brackets. In the following sample, the add function can optionally add a third number. This function appears as =CONTOSO.ADD(first, second, [third]) in Excel.JavaScriptTypeScript/** * Calculates the sum of the specified numbers * @customfunction * @param {number} first First number. * @param {number} second Second number. * @param {number} [third] Third number to add. If omitted, third = 0. * @returns {number} The sum of the numbers. */function add(first, second, third) { if (third === null) { third = 0; } return first + second + third;}/** * Calculates the sum of the specified numbers * @customfunction * @param first First number. * @param second Second number. * @param [third] Third number to add. If omitted, third = 0. * @returns The sum of the numbers. */function add(first: number, second: number, third?: number): number { if (third === null) { third = 0; } return first + second + third;}NoteWhen no value is specified for an optional parameter, Excel assigns it the value null. This means default-initialized parameters in TypeScript will not work as expected. Don't use the syntax function add(first:number, second:number, third=0):number because it will not initialize third to 0. Instead use the TypeScript syntax as shown in the previous example.When you define a function that contains one or more optional parameters, specify what happens when the optional parameters are null. In the following example, zipCode and dayOfWeek are both optional parameters for the getWeatherReport function. If the zipCode parameter is null, the default value is set to 98052. If the dayOfWeek parameter is null, it's set to Wednesday.JavaScriptTypeScript/** * Gets a weather report for a specified zipCode and dayOfWeek * @customfunction * @param {number} [zipCode] Zip code. If omitted, zipCode = 98052. * @param {string} [dayOfWeek] Day of the week. If omitted, dayOfWeek = Wednesday. * @returns {string} Weather report for the day of the week in that zip code. */function getWeatherReport(zipCode, dayOfWeek) { if (zipCode ===
