javascript - Excel office-js API - Insert values to a blank sheet -

how can insert values blank sheet?
way know of inserting values retrieving range , inserting values using values property, such as

range.getrange("a1:" + cellbottomright); range.load("values"); context.sync().then(function () {     range.values = twodimensionalarrayofvalues; }); 

is there simpler way using single function insert values, rather first retrieving range?

thanks!

edit:
i've been trying create new sheet , insert 2-dimensional array it, values inserted starting cell a1.
far, managed following:

let neesheet = context.workbook.worksheets.add("new sheet"); newsheet.activate(); newsheet.getrange("a1").values = twodimensionalarray; context.sync(); 

but didn't work.

how can work?
thanks!

(adding answer in response new information @avi12 added question above, under "edit")

philip's answer above correctly shows how insert single value cell a1 of worksheet. address specific scenario you've described in (updated) question, here code snippets (one in typescript , other in javascript) show how create new worksheet , add data worksheet, using 2-dimensional array of data. key thing point out here i'm retrieving range using getresizedrange (passing in dimensions of array), size of range matches size of data set i'm inserting it.

note: can , try these snippets using script lab (https://aka.ms/getscriptlab). install script lab add-in (free), choose "import" in navigation menu, , use following gist url: https://gist.github.com/kbrandl/01c4faf352c34286188311c1198f6307.

typescript:

async function run_ts() {     try {         await excel.run(async (context) => {              // define values inserted new sheet             let values = [["a1", "b1", "c1"], ["a2", "b2", "c2"]];               // create , activate new sheet             let sheets = context.workbook.worksheets;             let newsheet = sheets.add("new sheet ts");             newsheet.activate();              // add data new sheet             let range = newsheet.getrange("a1").getresizedrange(values.length - 1, values[0].length - 1);             range.values = values;              // sync             await context.sync();              console.log("finished run_ts function");         });     }     catch (error) {         officehelpers.ui.notify(error);         officehelpers.utilities.log(error);     } } 

javascript:

function run_js() {     excel.run(function (context) {          // define values inserted new sheet         var values = [["a1", "b1", "c1"], ["a2", "b2", "c2"]];          // create , activate new sheet         var sheets = context.workbook.worksheets;         var newsheet = sheets.add("new sheet js");         newsheet.activate();          // add data new sheet         var range = newsheet.getrange("a1").getresizedrange(values.length - 1, values[0].length - 1);         range.values = values;          // sync                 return context.sync()             .then(function () {                 console.log("finished run_js function");             });     })         .catch(function (error) {             officehelpers.ui.notify(error);             officehelpers.utilities.log(error);         }); }
